ACX500 Universal Access Router Overview

Juniper Networks ACX500 Universal Access Routers are principally designed to provide superior management for rapid provisioning to the access network. The ACX500 routers support rich Gigabit Ethernet capabilities for uplink, along with support Gigabit Ethernet interfaces in a compact form factor that is environmentally hardened and passively cooled. Seamless, end-to-end MPLS can be used to address legacy and emerging requirements to provide the foundation for a converged network that utilizes the same mobile backhaul infrastructure for business or residential services.

The routers have a built-in Routing Engine and one Packet Forwarding Engine. The Packet Forwarding Engine has one "pseudo" Flexible PIC Concentrator (FPC 0). Because there is no switching fabric, the single Packet Forwarding Engine takes care of packet forwarding.

  • Routing Engine—Provides Layer 3 routing services and network management.
  • Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.

The Juniper Networks ACX Series Routers are powered by the Junos operating system (Junos OS), which supports extensive Layer 2 and Layer 3 features, IP and MPLS with traffic engineering, rich network management, fault management, service monitoring and Operation, Administration, and Maintenance (OAM) capabilities, and an open software development kit (SDK) system that enables providers to customize and integrate operations with their own management systems. For a list of related Junos OS documentation, see http://www.juniper.net/techpubs/software/junos/.

As part of the mobile backhaul, an ACX Series router at the cell site and an MX Series router at the aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one Junos OS running on both platforms.

The ACX500 routers can be installed indoors as well as outdoors:

  • ACX500 Indoor—The compact ACX500 indoor routers are one rack unit (U; that is, 1.75 in. or 4.45 cm) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space. The chassis is a rigid sheet metal structure that houses all the other router components. The chassis of the ACX500 indoor router measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48 cm) (from the front-mounting brackets to the rear of the chassis). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks.
  • ACX500 outdoor—The compact ACX500 outdoor routers are environmental hardened, and can be deployed in an outdoor environment, such as on walls and poles. The chassis of the ACX500 indoor router measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The chassis of the ACX500 outdoor router with the Power over Ethernet (PoE) unit measures 16 in. (40.64 cm) high, 4.7 in. (11.93 cm) deep, and 10 in. (25.4 cm) wide. You need to purchase the pole-mounting kit or the wall-mounting kit from Juniper Networks to mount the router in an outdoor environment.

ACX500 Indoor Router Description

The ACX500 indoor routers contain a total of 10 ports that support 1-Gbps speed, eight of which are labeled COMBO. At any point of time, you can use a maximum of six ports.

The ports labeled COMBO (combination ports) consist of four Gigabit Ethernet ports that support RJ-45 connectors and four Gigabit Ethernet ports that support small form-factor pluggable (SFP) transceivers. Out of the four RJ-45 ports, three ports support Power over Ethernet (PoE+ and PoE++).

The two ports that are not part of the COMBO ports are Gigabit Ethernet SFP ports.

On the ACX500, the six ports that you can use at any point of time can be two Gigabit Ethernet SFP ports (non-combination) and four ports from the COMBO ports.

Juniper ACX500 - ACX500 Indoor Router Description - 1

NOTE: You can mix and match the four RJ-45 and SFP COMBO ports as long as the port numbers are unique.

For example, from the COMBO ports, you can use the 0/1/0 SFP port along with the 0/1/1 PoE+ RJ-45 port, but not the 0/1/0 PoE++ RJ-45 port, as the port numbers of the SFP and the RJ-45 ports are same (0/1/0).

The class-of-service (CoS) architecture for ACX Series routers is in concept similar to that for MX Series routers. The general architecture for ACX Series routers is shown in Figure 11 on page 14.

Based on the model, ACX Series routers contain a built-in Routing Engine and Packet Forwarding Engine and can contain both T1/E1 and Gigabit Ethernet Ports.

The Packet Forwarding Engine has one or two “pseudo” Flexible PIC Concentrators. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet forwarding.

Fixed classification places all packets in the same forwarding class, or the usual multifield (MF) or behavior aggregate (BA) classifications can be used to treat packets differently. BA classification with firewall filters can be used for classification based on IP precedence, DSCP, IEEE, or other bits in the frame or packet header.

However, the ACX Series routers can also employ multiple BA classifiers on the same physical interface. The physical interfaces do not have to employ the same type of BA classifier. For example, a single physical interface can use classifiers based on IP precedence as well as IEEE 802.1p. If the CoS bits of interest are on the inner VLAN tag of a dual-tagged VLAN interface, the classifier can examine either the inner or outer bits. (By default, the classification is done based on the outer VLAN tag.)

Eight queues per egress port support scheduling using the weighted deficit round-robin (WDRR) mechanism, a form of round-robin queue servicing. The supported priority levels are strict-high and default (low). The ACX Series router architecture supports both weighted random early detect (WRED) and weighted tail drop (WTD).

All CoS features are supported at line rate.

The packet pipeline through an ACX Series router is shown in Figure 12 on page 15. Note that the rate limiting is done with an integrated architecture along with all other CoS functions. Scheduling and shaping are supported on the output side.

NOTE:

  • The [edit logical-systems logical-system-name] hierarchy level is not supported on ACX Series routers.
  • TheACXSeriesroutersdoes not supportper-familymaximum transmission unit (MTU) configuration. The MTU applied to family inet gets applied to other families as well, even though it can be configured though CLI and visible in show Interface extensive output. The only way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet levels, and let it calculate for each family automatically.

Alarm Contact Port on ACX500 Routers

The ACX500 router has four external alarm contacts (also known as potential free contacts) for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin D-type connector. The external alarm contact has 15 pins that accept a single core wire from external alarm devices. A DE15 alarm cable is required to connect the ACX500 router to external alarm devices. Use the gauge wire appropriate for the external device that you are connecting.

Whenever a system condition triggers an alarm, the alarm relay contacts are activated, which in turn activates the external alarm devices. The alarm setting is open or closed.

You can connect and configure two output alarms and four input alarms. Two additional output alarms are reserved and are used to indicate major and minor system alarms. Each output and input alarm has two contacts for connecting the router to external alarm devices. Contact 1 of each alarm can be configured as Normally Open [NO] or Normally Closed [NC] through the CLI. Contact 2 of each alarm functions as a reference [REF] or negative potential terminal for Contact 1 of the corresponding alarm and provides a current path for external alarm devices. Table 9 on page 40 describes the functions of the alarm contacts.

Table 9: Alarm Relay Contact Functions

Contact NameFunctionContact Name
Normally Open (NO)Content 1 is not flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current flows, the closed alarm is generated.
Normally Closed (NC)Current is flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current stops flowing, the open alarm is generated.
Reference (REF)Provides the current path for the external alarm-reporting device and functions as a reference or negative potential terminal for Contact 1.

Figure 21 on page 40 shows an example of a wiring diagram for a simple output alarm-reporting device. In this case the device is a light bulb that illuminates when the device encounters a condition that activates the red alarm LED and relay contacts. The alarm relay contacts can also be used to activate other devices such as bells or buzzers.

Clocking Ports on ACX500 Routers

The clocking ports distribute a synchronized clock signal throughout the router by locking onto a clock signal originating from an internal clock source or by connecting to an external clock source.

The reference clock inputs can be Ethernet recovered clocks, IEEE 1588v2 recovered clocks, or xDSL NTU-R timing clocks. Externally available reference clocks are 1 pulse per second (PPS). The two SubMiniature B (SMB, 1 PPS input and 1 PPS output) connectors on the front panel of the router connect to external clock signal sources. The clocking ports provide the synchronized output clocks from any one of the above reference inputs based on the clock's priority.

Internal clock sources within the ACX500 routers include:

• 1 PPS SMB connectors (one input and one output)
• Time of day (TOD) RJ-45 port (supports RS-422)
- Synchronous Ethernet support on RJ-45 and SFP ports as timing input or output
- Packet timing (IEEE 1588v2) includes:
- Timing input when configured as ordinary clock (OC) or boundary clock (BC)
- Timing output when configured as BC

Cooling System and Airflow in ACX500 Routers

The ACX500 indoor routers do not contain fans, and are passively cooled through air vents. The air vents in the router are located on both the sides of the router and also on top of the router (see Figure 23 on page 47). Temperature sensors in the chassis monitor the temperature within the chassis. If the temperature inside the chassis rises above the threshold, the router shuts down automatically.

Figure 23: Cooling System and Airflow in the ACX500 Indoor Router
Rear Juniper 4G300-X Front JUNOS B-007836

The ACX500 outdoor routers do not contain fans, and are passively cooled by internal heat sinks and external cooling fins (see Figure 24 on page 48). The external cooling fins on the body of the ACX500 outdoor router help to dissipate the heat. Unlike the ACX500 indoor routers, the ACX500 outdoor routers do not have air vents.

ACX500 Router Environmental Specifications

The ACX500 indoor router must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Ensure that the following environmental guidelines are followed for the ACX500 indoor router:

  • The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the router cooling system.
  • Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the intake air is too warm, the router might overheat, leading to the router temperature monitor shutting down the router to protect the hardware components.
  • The rack or cabinet must have an adequate supply of cooling air. Allow a minimum of 1 meter/second of airflow over the ACX500 indoor router.

Juniper ACX500 - ACX500 Router Environmental Specifications - 1

NOTE: Depending on the ambient temperature, it might take up to 5 minutes for the router to heat up to the operating temperature.

Cabinet Requirements for ACX500 Indoor Routers

You can mount the indoor router in a cabinet that contains a 19-in. (48.3 cm) rack.

Cabinet requirements consist of:

  • Cabinet size
  • Clearance requirements
    • Cabinet airflow requirements

Table 26 on page 59 provides the cabinet requirements and specifications for the router.
Table 26: Cabinet Requirements and Specifications for the ACX500 Indoor Router

GuidelinesCabinet Requirement
Cabinet sizeYou can mount the router in a cabinet that contains a 19-in. (48.3 cm) rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org).NOTE: The cabinet must meet the strength requirements to support the weight of the router.The minimum cabinet size must be able to accommodate the maximum external dimensions of the router.
Cabinet clearanceThe outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.3 cm).The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front door and the inside of the rear door.
Cabinet airflow requirementsWhen you mount the router in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.Ensure an adequate cool air supply to dissipate the thermal output of the router or routers.When deploying the router in harsh environments, allow a 1-rack unit (U) gap above and below the router.Minimum 1 meter/second airflow in any directionEnsure that the cabinet allows the hot exhaust air from the chassis to exit the cabinet without recirculating into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.Install the router in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust. This space maximizes the clearance for critical airflow.Route and dress all cables to minimize the blockage of airflow to and from the chassis.Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the router and cabinet.A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

This topic describes signal loss, attenuation, and dispersion in fiber-optic cable. For information about calculating power budget and power margin for fiber-optic cable, see "Calculating Power Budget and Power Margin for Fiber-Optic Cables" on page 72 and Supported Network Interface Standards by Transceiver for ACX Series, M Series, MX Ser and T Series Routers or Supported Network Interface Standards by Transceiver for PTX Series Routers.

  • Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 71
  • Attenuation and Dispersion in Fiber-Optic Cable on page 72

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable

Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results. Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber.

Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.

Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

Correct functioning of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated correctly. Attenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must have enough light available to overcome attenuation.

Dispersion is the spreading of the signal over time. The following two types of dispersion can affect an optical data link:

  • Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.
  • Modal dispersion—Spreading of the signal over time resulting from the different propagation modes in the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion limits maximum link length.

An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be less than the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU) document G.957.

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.

Calculating Power Budget and Power Margin for Fiber-Optic Cables on page 72.

Calculating Power Budget and Power Margin for Fiber-Optic Cables

Use the information in this topic and the information in Supported Network Interface Standards by Transceiver for ACX Series, M Series, MX Series, and T Series Routers of Supported Network Interface Standards by Transceiver for PTX Series Routers to calculate the power budget and power margin for fiber-optic cables.

To calculate the power budget and power margin, perform the following tasks:

  1. Calculating Power Budget for Fiber-Optic Cable on page 73
  2. Calculating Power Margin for Fiber-Optic Cable on page 73

Calculating Power Budget for Fiber-Optic Cable

To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit. When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at the worst-case levels. To calculate the worst-case estimate of power _B budget (P you assume minimum transmitter power) (and minimum receiver sensitivity):(P

$$ P _ {B} = P _ {T} - P _ {R} $$

The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm):

$$ P _ {B} = P _ {T} - P _ {R} $$

$$ P _ {B} = - 1 5 \mathrm{dBm} - (- 2 8 \mathrm{dBm}) $$

$$ P _ {B} = 1 3 \mathrm{dB} $$

Calculating Power Margin for Fiber-Optic Cable

After calculating a link's power budget, you can calculate the power margin (P represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget _B ) (PA worst-case estimate of assumes maximum LL:

$$ P _ {M} = P _ {B} - L L $$

P_M greater than zero indicates that the power budget is sufficient to operate the receiver.

Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 27 on page 73 lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation.

Table 27: Estimated Values for Factors Causing Link Loss

Estimated Link-Loss ValueLink-Loss Factor
Higher-order mode lossesSingle-mode—NoneMultimode—0.5 dB
Modal and chromatic dispersionSingle-mode—NoneMultimode—None, if product of bandwidth anddistance is less than 500 MHz-km
0.5 dBConnector
0.5 dBSplice
Fiber attenuationSingle-mode—0.5 dB/kmMultimode—1 dB/km

The following sample calculation for a 2-km-long multimode link with a power budget ( P_B ) of 13 dB uses the estimated values from Table 27 on page 73 to calculate link loss (LL) as the sum of fiber attenuation (2 km @ 1 dB/km, or 2 dB) and loss for five connections (0.5 dB per connector, or 2.5 dB) and two splices (0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margins (Calculated as follows:

$$ P _ {M} = P _ {B} - L L $$

$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{km} (1 \mathrm{dB/km}) - 5 (0. 5 \mathrm{dB}) - 2 (0. 5 \mathrm{dB}) - 0. 5 \mathrm{dB} $$

$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{dB} - 2. 5 \mathrm{dB} - 1 \mathrm{dB} - 0. 5 \mathrm{dB} $$

$$ P _ {M} = 7 \mathrm{dB} $$

The following sample calculation for an 8-km-long single-mode link with a power budget ( P_B ) of 13 dB uses the estimated values from Table 27 on page 73 to calculate link loss (LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power marginal (Pulated as follows:

$$ P _ {M} = P _ {B} - L L $$

$$ P _ {M} = 1 3 \mathrm{dB} - 8 \mathrm{km} (0. 5 \mathrm{dB/km}) - 7 (0. 5 \mathrm{dB}) $$

$$ P _ {M} = 1 3 \mathrm{dB} - 4 \mathrm{dB} - 3. 5 \mathrm{dB} $$

$$ P _ {M} = 5. 5 \mathrm{dB} $$

In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.

ACX500 Router AC Power Cord Specifications

Each AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.

You can order detachable AC power cords, each approximately 8 ft (2.5 m) long that supply AC power to the router. The C15 appliance coupler at the female end of the cord, as described by International Electrotechnical Commission (IEC) standard 60320, inserts into the AC appliance inlet coupler. The plug at the male end of the power cord fits into the power source receptacle that is standard for your geographic location.

Requirements and Specifications for Installing a GNSS Antenna

This section describes the guidelines and procedure for installing a global navigation satellite system (GNSS) antenna to ensure an optimal signal reception. The ACX500 routers use the GNSS signals for timing and synchronization features.

Juniper ACX500 - Requirements and Specifications for Installing a GNSS Antenna - 1

NOTE: The GNSS port and LEDs on the ACX500 router chassis are labeled GPS.

Consider the following guidelines before you install the GNSS antenna:

• RF site survey for antenna location
• RF environment details, such as transmission source and proximity
- Grounding plane
- Cable routing

We recommend the guidelines and procedure described in this chapter to ensure optimum GNSS signal reception for the ACX500 router.

Requirements for Installing a GNSS Antenna

This section describes the requirements to correctly install a GNSS antenna on an ACX500 router. Table 35 on page 88 lists the items that you must provide to install the GNSS antenna.

Table 35: Antenna Mounting Requirements

Item
GNSS L1/G1 antenna with a frequency band of 1575 to 1610 MHz +/-10 MHz, 3 dB bandwidth
Antenna mount that is used to secure the GNSS antenna
Mounting area clear for at least two meters of any metal or other material that could act as a shield and block the GNSS signal
360° unobstructed clear view of the sky from 15° above horizon
Clamps, cable ties, and so on, to secure cable

ACX500 Router GNSS Antenna Signal Gain Requirements

The ACX500 router requires an active GNSS antenna with built-in low-noise amplifier (LNA) for optimal performance. The LNA amplifies the received satellite signals first to compensate the loss due to the cable, and second to lift the signal amplitude to a range that is required by the receiver.

The cables and connectors that are used to connect the GNSS antenna to the receiver cause signal loss, which can be up to 13 dB. The signal gain due to the LNA amplification can be up to 30 dB.

When calculating the required signal for the router, keep in mind the loss due to the cable and connectors, and the gain due to the LNA amplification. Therefore, if the loss due to the cables and connectors is 13 dB and the LNA signal gain is 30 dB, then the signal gain available to the receiver is 17 dB. We recommend that you limit the available gain to less than 35 dB. Also, ensure that the LNA you select has a low noise profile.

The recommended range of the LNA signal gain, after compensating the loss due to the cables and connectors, at the receiver is 22 dB through 30 dB (with a minimum of 17 dB and a maximum of 35 dB).

General ACX500 GNSS Antenna Mounting and Installation Recommendations

Ideally, the GNSS antenna should be mounted where a 360^ unobstructed clear view of the sky (at 15^ angle from horizontal) is available to enable a connection to visible GNSS satellites. The ideal mounting location is a roof, tower, or an antenna mast, high above any obstruction or any device that can cause signal interference. We recommend a location that has the following characteristics:

- Clear unobstructed view of the sky in all directions— 360^ view.

- Away from high-power transmitters and radar antennas.

- At least 3 feet (1 m) away from any metallic objects, such as radio tower, other antenna mast, electrical poles, and so on.

- At least 3 feet (1 m) below the highest point of a lightning rod.

- Convenient path for running the outdoor coaxial cable from the GNSS antenna to the network.

• Install the router in compliance with the local, national, or international electrical codes:

- United States—National Fire Protection Association (NFPA 70), United States National Electrical Code, Article 810

• Canada—Canadian Electrical Code, Section 54

- Protect the GNSS antenna from environmental conditions such as foot traffic, standing water, and any mechanical stressor that might compromise the cable integrity. Wherever applicable, run smaller size cabling through dedicated outdoor-rated electrical conduit.

Juniper ACX500 - General ACX500 GNSS Antenna Mounting and Installation Recommendations - 1

WARNING:

- Locate the GNSS antenna away from power lines, lighting systems, HVACs (heating, ventilation and air conditioning), and power circuits.

- When installing the GNSS antenna, do not touch power lines or other sources of "live" power.

- Have a qualified technician or a certified electrician perform the installation.

- Observe all local and regulatory standards and ordinances.

- Grounding the unit (metal mast or ground cable to the unit's base) is required for the lightning protection to work properly.

The ACX500 Timing Server can maintain accurate time even if an antenna is mounted in a location that has limited visibility of GNSS satellites; however, we recommend obstructions should be minimized. Limitations to satellite visibility for an antenna include overhanging foliage or tall structures. Such structures can block the GNSS signal from the antenna and cause gaps in the GNSS satellite signal reception. In locations where satellite visibility is limited, keep in mind the following guidelines:

- Position the antenna on the side of the structure with good visibility toward the equator where more satellites are visible. For example, if you are in the northern hemisphere, place the unit on the southern side of the structure unless that view is restricted or blocked. If that view is restricted or blocked, place the unit on the east or west side of the structure. Avoid the polar side where there are fewer visible satellites.

- Ensure that the GMT time zone parameter is set while you configure the Timing Server.

- To avoid any potential damage to the GNSS antenna and the router, do not install the antenna in the proximity of any transmitting RF or high-voltage power sources. This is both a hardware precaution as well as a personnel safety precaution. Follow all local building code requirements, as well as the local building electrical codes for power and grounding.

  • You must mount the antenna above and away from any electrical systems such as lift mechanisms, air handlers, HVACs, and other electrical or mechanical machinery.
  • The GNSS signals can be reflected by objects such as metal, walls, and shielded glass parts. Do not install the antenna near good light-reflecting surfaces. Failing to do so might result in distorted GNSS signals.
  • To avoid multipath reflections, do not place the antenna near a wall, window, or other large vertical objects.
  • To prevent damage from lightning, do not place the GNSS antenna at the highest point of the building.
  • You must locate the GNSS antenna at least 3 feet (1 m) away from any metallic objects such as radio tower, other antenna mast, electrical poles, and so on. See Figure 33 on page 91.
  • Allow at least 6 feet (2 m) of separation between GNSS antennas. See Figure 33 on page 91.
  • The antenna must have an unobstructed 360^ view of the sky from 15^ above the horizon. See Figure 34 on page 91.
  • Locate the antenna within a reasonable distance of the building cable entry point.
  • Mount the antenna to any fixed surface by using the GNSS antenna mast or stanchion clamp. You may install the antenna to a vertical or horizontal surface based on the surface availability as long as the other antenna placement requirements are met.
  • You must connect the GNSS antenna to a surge or lightning arrestor. The surge arrester must be near the antenna location or at the building entrance, and must be grounded to the building ground. This ensures that the antenna has a direct path to ground and is away from any sensitive electrical or electronic GNSS equipment.
  • You must protect the GNSS antenna cabling from environmental conditions such as foot traffic, standing water, and any mechanical stress that might compromise or affect the cable integrity. We recommend, where applicable, to run smaller-size cabling through a dedicated outdoor-rated electrical conduit.

Installing the ACX500 GNSS Antenna

To install the GNSS antenna, follow the guidelines specific to the selected GNSS antenna.

The following steps are part of a general procedure for installing any standard GNSS antenna:

  1. Mount the antenna to any fixed surface by using the GNSS antenna mast or stanchion clamp in an area with clear and open view of the sky.
  2. Route the coaxial cable from the newly installed antenna into the building following the manufacturer's antenna safety guidelines.
  3. Route the coaxial cable from the building's head-end to the server's installation site, and connect it to the router's GNSS port (RF input). See "Front Panel of an ACX500 Indoor Router" on page 33 and Figure 5 on page 7 for the GNSS antenna port location on the ACX500 routers.
  4. Verify that the router is receiving good signal through the GNSS antenna by observing the GPA 1PPS LED on the ACX500 router.

Juniper ACX500 - WARNING: - 4

WARNING:

  • Have a qualified technician and or certified electrician perform the installation.
  • Observe all local and regulatory standards and ordinances.
  • Grounding the unit (metal mast or ground cable to the unit's base) is required for the lightning protection to work properly.

Juniper ACX500 - WARNING: - 1

WARNING: Do not install the GNSS antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When you install the antenna, take extreme care not to come into contact with such circuits, because they might cause serious injury or death. For proper installation and grounding of the antenna, refer to local, national, and international electrical codes (for example, U.S.: NFPA 70, National Electrical Code, Article 810; Canada: Canadian Electrical Code, Section 54; and so on).

Vout = 3.3 V (+/-5%) - 22 ohm x I-Load45 mAmp (maximum)

Juniper ACX500 - WARNING: - 2

NOTE: ACX500 GNSS output current supports only 3 V antenna voltage, which work with maximum current and supports voltage tolerance as calculated in Table 37 on page 94.

For antennas that do not have a voltage rating of 3 V DC, we recommend that you use an active splitter or amplifier as required (DC block from ACX500 and antenna power from external power source) that supports the antenna voltage.

ACX500 GNSS Antenna Surge Protection

For a roof antenna, we recommend that you provide additional surge protection in accordance to the regulations and standards for lightning protection in the country where the ACX500 router is installed.

Juniper ACX500 - ACX500 GNSS Antenna Surge Protection - 1

NOTE: We recommend that you use an external first-level fast lightning protector that has clamping voltages of 15 V and 20 V.

Juniper ACX500 - ACX500 GNSS Antenna Surge Protection - 2

WARNING: Make sure that grounding is available and that it meets local and national electrical codes. For additional lightning protection, use lightning rods, lightning arrestors, or surge suppressors.

Antenna Installation Verification

After installing the GNSS antenna, verify that the installation is properly done:

  • Verify that all the cables and connectors are installed correctly and securely fastened. Ensure that all connectors have been protected from weather by using the latest RF cabling installation and protection guidelines.
  • Verify that the GNSS antenna interface status is good in the respective GPS monitoring application. Also, verify the status of the GPS 1PPS LED on the ACX500 router.
  • Verify that the cable service loop or the drip loop is utilized and is sufficient.
  • Unlike other radio device, do not apply any tape or chemical protection to the connectors. The recommended connectors are weatherproof, and adding any protection makes the warranty void and can lead to expensive repairs.

• Antenna Selection Guidelines on page 95
- Recommended GNSS Antenna Specifications on page 95

Antenna Selection Guidelines

Keep the following points in mind while selecting the appropriate GPS antenna for the ACX500 router:

  • The ACX500 router requires an active GPS antenna with built-in low-noise amplifier (LNA) for optimal performance.
  • The ACX500 router supports only 3 V DC voltage. For antennas that do not have a voltage rating of 3 V DC, we recommend that you use an active splitter or amplifier as required (DC block from ACX500 and antenna power from external power source) that supports the antenna voltage. See Table 37 on page 94 for more details on available voltage and current for 3 V antenna application.
  • An active splitter or amplifier (DC block from ACX500 and antenna power from external power source) can also be inserted into the antenna path near the receiver for additional gain or added voltage support range. The use of a parasitic nonactive amplifier is not recommend.

To use a GNSS antenna with the ACX500 router, the antenna must be a GNSS L1/G1 antenna (1575–1610 MHz). At present there are several GNSS antennas available in the market that meet the ACX500 router criteria.

We recommend that you use the following GNSS antenna with the ACX500 routers:

Weatherproofing the ACX500 Outdoor Router

Juniper ACX500 - Weatherproofing the ACX500 Outdoor Router - 1

NOTE: The information provided in this topic is applicable for both the ACX500 outdoor router variants—ACX500 outdoor router and ACX500 outdoor router with PoE.

• Weatherproofing Overview on page 121
- Accessing and Weatherproofing the Interface Ports on page 122
- Accessing and Weatherproofing the Management Ports on page 133

Weatherproofing Overview

The ACX500 outdoor router meets the requirement of the International Protection Code (IP65) for dust-tight environments and ingress against water jetting environment.

To protect the router's inner components from external environmental factors, the router is environmentally hardened and the chassis is ruggedized. The router is fanless and ventless, and supports passive cooling for outdoor deployments in extreme weather conditions.

There are two parts to securing and weatherproofing the ACX500 outdoor router—weatherproofing the interface ports and cables, and weatherproofing the management components.

The interface cables are arranged inside the cable connector unit (see Figure 50 on page 127 and Figure 54 on page 131), which makes them waterproof and dustproof. The metal interface and management port covers on the router lock and seal the respective port chambers from external environmental factors.

Juniper ACX500 - Weatherproofing Overview - 1

NOTE: The ACX500 outdoor router do not power on if the interface and the management port chambers are open. Ensure that the interface and the management port chambers are closed before you power on the router. This is an IP65 requirement for weatherproofing the router.

Figure 45 on page 122 shows the ACX500 outdoor router along with the weatherproofing caps, also called weather seal caps. The figure also shows the weatherproofing port covers, also called weather seal covers, protecting the interface and management port components from external environment.

Technical diagram of a vehicle chassis with numbered components and labeled parts

Interface port chamber with weather seal cover3-1- Management port chamber with weather seal cover
2-Cable connector ports with weather seal cap4-Power port with weather seal cap

To know which components are housed inside the interface and the management port covers, see "Front Panel of an ACX500 Outdoor Router" on page 35.

Ensure that you have the following parts available:

• Cable connector units (provided)
- Hex screwdriver
- Slotted screwdriver

Accessing and Weatherproofing the Interface Ports

In the ACX500 outdoor router, all the interface ports (Gigabit Ethernet SFP and RJ-45 ports) are located in a small chamber on the front top of the router. You can access the interface ports to install the transceivers and check LED status through this interface

port chamber. The metal cover locks and seals the chamber from external environmental factors. See Figure 45 on page 122.

  • Weatherproofing the Interface Ports—Gigabit Ethernet SFP on page 123
  • Weatherproofing the Interface Ports—Gigabit Ethernet RJ-45 on page 128

Weatherproofing the Interface Ports—Gigabit Ethernet SFP

To access and weatherproof the Gigabit Ethernet SFP interface ports and cables:

  1. Unscrew and remove the six screws from the metal cover on top of the router that covers the interface port chamber. Keep the screws for later use.

In Figure 45 on page 122 from left to right, the first three cable connector inlets are for the three Gigabit Ethernet ports supporting SFP transceivers. The fourth inlet is for the cables for the three Gigabit Ethernet RJ-45 ports.

  1. Remove the weather seal cap from the cable inlet port on the router by using a slotted screwdriver. See Figure 46 on page 123. Keep the weather seal cap in a safe place for future use.

The weather seal caps prevent dust and water from entering into the router when the router or the interface port is not in use.

Figure 46: Removing the Weather Seal Cap

natural_image Technical line drawing of an automotive electrical connector with a wrench and circular component (no text or symbols)

Juniper ACX500 - Weatherproofing the Interface Ports—Gigabit Ethernet SFP - 2

WARNING: Ensure that you have the weather seal caps on the cable inlet ports that are not in use. Failing to do so might allow water and dust to enter the router, resulting in router failure.

  1. Unscrew and remove the corresponding cable connector unit from the cable inlet port. See Figure 47 on page 124.

The cable connector unit consists of three components—the outer connector enclosure, the connector screw, and the cable seal. The front end of the outer cable connector enclosure is from where the interface cable enters the router, and the rear end with screw thread connects directly to the chassis cable port on the router. The connector screw houses a rubber cable seal, and screws fit tightly in the cable connector enclosure. The cable seal is a small cylindrical rubber structure with grooves or holes for the cables to pass through. The cable seal sits tightly in the connector screw and prevents water and dust particles from entering the router.

Juniper ACX500 - Weatherproofing the Interface Ports—Gigabit Ethernet SFP - 3

NOTE: The cable seal with single groove must be used for the SFP cables, and that with three grooves must be used for the RJ-45 cables.

Juniper ACX500 - Connecting DC Power Cables to the ACX500 Indoor Router - 25

NOTE: A DC-powered router needs to be connected with the outdoor DC power cord that is purchased from Juniper Networks, and which is compatible with the ACX500 outdoor router. To supply sufficient power, the DC input wiring on the facility DC source is capable of supplying at least 5 A @-48 VDC per input for each power supply. We recommend that the 48-VDC facility DC source should be equipped with a circuit breaker rated at 5 A @-48 VDC minimum, or as required by local code.

For other nominal input voltages such as 24VDC, -60 VDC, were recommend that the circuit breaker rating be appropriately sized or rated, and as required by local code.

  1. Tighten the power cord plug screw.

The power cord plug screw prevents water and dust from entering the terminal.

  1. Verify that the power cabling is correct, that the power cables do not touch or block access to router components, and that they do not drape where people could trip on them.

  2. Observe the system LED on the router. If an DC power supply is functioning normally, the system LED lights green steadily.

If the system LED is not lit, the power supply is not functioning normally. Repeat the cabling procedures.

CHAPTER 16

Configuring Junos OS on ACX500 Route

- Performing Initial Software Configuration for the ACX500 Router on page 155

Performing Initial Software Configuration for the ACX500 Router

The ACX500 routers are shipped with Junos OS preinstalled and ready to be configured when the router is powered on. One 4-GB internal NAND flash memory device is divided into two partitions (da0s1 and da0s2). One partition is marked as the active partition, and the other partition functions as an alternate partition. The NAND flash device acts as the hard drive. One USB port on the front panel accepts a USB storage device (usb0) that can also function as an alternate boot device.

When the router boots, it first attempts to start the image on the USB flash memory device. If a USB flash memory device is not inserted into the router or the attempt otherwise fails, the router next tries the active partition on the NAND flash device, and then tries the alternate partition on the NAND flash device.

You configure the router by issuing Junos OS command-line interface (CLI) commands, either on a console device attached to the CONSOLE port on the front panel, or over a telnet connection to a network connected to the Routing Engine MGMT port on the front panel.

Gather the following information before configuring the router:

  • Name that the router will use on the network
  • Domain name that the router will use
  • IP address and prefix length information for the Ethernet interface
    • IP address of a default router
    • IP address of a DNS server
  • Password for the root user

This procedure connects the router to the network but does not enable it to forward traffic. For complete information about enabling the router to forward traffic, including examples, see the Junos OS configuration guides.

To configure the software:

  1. Verify that the router is powered on.
  2. Log in as the "root" user. There is no password.

  3. Start the CLI.

Routine Maintenance Procedures for the ACX500 Router

Purpose For optimum router performance, perform preventive maintenance procedures.

Action Inspect the installation site for moisture, loose wires or cables, and excessive dust. Make sure that airflow is unobstructed around the router and into the air intake vents. •Check the status-reporting devices on the front panel—system LED.

Related Documentation Maintaining Cables That Connect to ACX500 Network Ports on page 169. •Maintaining the ACX500 Uplink Ports on page 170

Maintaining Cables That Connect to ACX500 Network Ports

Purpose For optimum router performance, verify the condition of the cables that connect to the network ports.

Action On a regular basis:

  • Place excess cable out of the way. Do not allow fastened loops of cable to dangle from the connector, because this stresses the cable at the fastening point. Putting fasteners on the loops helps to maintain their shape.
  • Keep the cable connections clean and free of dust and other particles, which can cause drops in the received power level. Always inspect cables, and clean them if necessary before connecting an interface.
  • Label both ends of the cables to identify them.
    The following guidelines apply specifically to fiber-optic cables:

- When you unplug a fiber-optic cable, always place a rubber safety plug over the transceiver on the faceplate and on the end of the cable.

- Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic cables so that they do not support their own weight as they hang to the floor. Never let fiber-optic cable hang free from the connector.

- Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage the cable and cause problems that are difficult to diagnose.

- Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments can cause damage to the instruments that is expensive to repair. Instead, attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easy and inexpensive to replace.

- Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.

To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the cleaning kit you use.

After you clean an optical transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such as the Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning kit you use.

  • System alarms indicate a missing rescue configuration. System alarms are preset and cannot be modified, although you can configure them to appear automatically in the J-Web interface display or CLI display.

Alarm Severity Classes

Alarms on ACX Series routers have two severity classes:

  • Major (steady red)—Indicates a critical situation on the router that has resulted from one of the following conditions. A red alarm condition requires immediate action.
    • One or more hardware components have failed.
    • One or more hardware components have exceeded temperature thresholds.
  • An alarm condition configured on an interface has triggered a critical warning.
  • Minor (blinking red)—Indicates a noncritical condition on the router that, if left unchecked, might cause an interruption in service or degradation in performance. A minor alarm condition requires monitoring or maintenance.

A missing rescue configuration generates a minor system alarm.

Preventing Electrostatic Discharge Damage to an ACX500 Router

Many router hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:

• Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact with your skin.

Juniper ACX500 - Preventing Electrostatic Discharge Damage to an ACX500 Router - 1

CAUTION: For safety, periodically check the resistance value of the ESD strap. The measurement should be in the range of 1 through 10 Mohms.

  • When handling any component that is removed from the chassis, make sure the equipment end of your ESD strap is attached to one of the electrostatic discharge points on the chassis (see Figure 78 on page 196).
  • Avoid contact between the component and your clothing. ESD voltages emitted from clothing can still damage components.
  • When removing or installing a component, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 79 on page 197). If you are returning a component, place it in an electrostatic bag before packing it.

Fire Safety Requirements for Juniper Networks Devices

  • General Fire Safety Requirements on page 199
    • Fire Suppression on page 199
    • Fire Suppression Equipment on page 199

General Fire Safety Requirements

In the event of a fire emergency involving network devices, the safety of people is the primary concern. Establish procedures for protecting people in a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, establish procedures to protect your equipment in a fire emergency. Juniper Networks products should be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment, and that you observe all local fire, safety, and electrical codes and ordinances when installing and operating your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, first turn off power to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide (CO_2) and Halotron, are most effective for suppressing electrical fires. Type C fire extinguishers displace the oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, use this type of inert oxygen displacement extinguisher instead of an extinguisher that leave residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers) near Juniper Networks devices. The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.

In addition, in minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

Juniper ACX500 - Fire Suppression Equipment - 1

NOTE: To keep warranties effective, donotuseadrychemical fire extinguisher to control a fire at or near a Juniper Networks device. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.

We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

ACX500 Chassis Lifting Guidelines

The weight of a fully configured ACX500 indoor router is about 8.6 lb (3.9 kg). The AC-powered ACX500 outdoor router weighs about 18.2 lb (8.3 kg) and the DC-powered ACX500 outdoor router weighs about 17.5 lb (7.9 kg). The AC-powered ACX500 outdoor router with PoE weighs 18.7 lb (8.5 kg), and the DC-powered router weighs 18.6 lb (8.4 kg). Observe the following guidelines for lifting and moving the router:

- Before moving the router, read the guidelines in "Site Preparation Checklist for ACX500 Routers" on page 53 to verify that the intended site meets the specified power, environmental, and clearance requirements.

- Before lifting or moving the router, disconnect all external cables.

To lift routing devices and components, use the following standard lifting guidelines:

- Up to 39.7 lb (18 kg)—one person required to lift.

- 39.7 lb (18 kg) to 70.5 lb (32 kg)—two or more persons required to lift.

- 70.5 lb (32 kg) to 121.2 lb (55 kg)—three or more persons required to lift.

- Above 121.2 lb (55 kg) material handling systems (such as levers, slings, lifts and so on) must be used. When this is not practical, specially trained persons or systems must be used (riggers or movers).

- As when lifting any heavy object, lift most of the weight with your legs rather than your back. Keep your knees bent and your back relatively straight and avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

ACX500 DC Power Electrical Safety Guidelines

The following electrical safety guidelines apply to a DC-powered router:

- A DC-powered router is equipped with a DC terminal block that is rated for the power requirements of a maximally configured router. To supply sufficient power, terminate the DC input wiring on a facility DC source capable of supplying at least 5 A @ -48 VD per input for each power supply. We recommend that the 48 VDC facility DC source should be equipped with a circuit breaker rated at 5 A @ -48 VDC) minimum, or as required by local code.

Incorporate an easily accessible disconnect device into the facility wiring. In the United States and Canada, the 48 VDC facility should be equipped with a circuit breaker rated a minimum of 125 percent of the power provisioned for the input in accordance with the National Electrical Code in the US and the Canadian Electrical Code in Canada.

- Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate gauge wire to handle up to 5 A

  • Be sure to connect the ground wire or conduit to a solid office (earth) ground. A closed loop ring is recommended for terminating the ground conductor at the ground stud.
  • Ensure that the polarity of the DC input wiring is correct. Under certain conditions, connections with reversed polarity might trip the primary circuit breaker or damage the equipment.
  • For personal safety, connect the green and yellow wire to safety (earth) ground at both the router and the supply side of the DC wiring.
  • The marked input voltage of -48 VDC for a DC-powered router is the nominal voltage associated with the battery circuit, and any higher voltages are only to be associated with float voltages for the charging function.
  • Because the router is a positive ground system, you must connect the positive lead to the terminal labeled +, the negative lead to the terminal labeled -, and the earth ground to the chassis grounding points.

Site Electrical Wiring Guidelines for Juniper Networks Devices

• Distance Limitations for Signaling on page 229
• Radio Frequency Interference on page 230
• Electromagnetic Compatibility on page 230

Distance Limitations for Signaling

Improperly installed wires can emit radio interference. In addition, the potential for damage from lightning strikes increases if wires exceed recommended distances or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices. If your site has previously experienced such problems, you might want to consult experts in electrical surge suppression and shielding.

Radio Frequency Interference

You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors. If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Electromagnetic Compatibility

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, you might want to seek expert advice. Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and receivers in the network device and conduct power surges over the lines into the equipment, resulting in an electrical hazard. It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

Juniper ACX500 - Electromagnetic Compatibility - 1

CAUTION: To comply with intrabuilding lightning and surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

Juniper ACX500 - Electromagnetic Compatibility - 2

WARNING: The intrabuilding ports of the equipment or subassembly are suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding ports of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
