Introducing CTP Platforms

Juniper Networks CTP Series Circuit to Packet platforms provide advanced technology and features required to reliably transport legacy time-division multiplexing (TDM) and other circuit-based applications across next-generation IP networks. CTP platforms create an IP packet flow from a serial data or analog voice connection at one end and provide the necessary processing to re-create the serial bit stream or analog signal from the received packet flow at the other end.

CTP platforms provide compact and lightweight chassis, high port density, and multiple Ethernet interfaces. Each CTP platform runs the CTP operating system (CTPOS) and can be managed by the Juniper Networks CTPView Network Management System, a secure, Web-based management tool for provisioning, managing, running diagnostics, monitoring, and reporting on all CTP devices and circuits in the network.

CTP2008 Platform

The Juniper Networks CTP2008 Circuit to Packet platform is a 3-U high, full-rack wide chassis designed for tabletop or shelf installation. It can also be installed in a rack with the supplied rack-mounting kit. The CTP2008 platform has one removable interface module and one removable processor module, and is available in both AC-powered and DC-powered versions. It has a removable fan tray, and airflow is side-to-side. See Figure 1 on page 3, Figure 2 on page 4, and Figure 3 on page 4.

Figure 1: CTP2008 Chassis (AC and DC Version, Front View)

The front panel comprises the following components (see Figure 1 on page 3):

- Interface module—Frame processing and forwarding engines. - Processor module—Two slots are available on this module for an optional fiber Gigabit Ethernet or Fast Ethernet PMC module. The primary SC connector is on the left side.

- Console port—This connector is not used by the CTP device.

- Power supply extractor—Push the button to eject the power supply module.

- PMC I/O—Both I/Os are supported.

- Clock module.

- Power supply—Use a standard IEC power cord for the AC version. Use a 22-AWG fork terminal connector for the DC version. Power redundancy is supported for the DC version.

There are no power switches on CTP2000 Series DC models, so a readily accessible disconnect device must be provided as part of the electrical installation of the unit. We recommend the 22-AWG wire for DC power terminals.

- Ethernet connection—Provides the 1-Gbps Ethernet connection to the IP network by means of a local Ethernet switch or router.

- USB connectors for console connection—Provides an asynchronous tty connection for locally configuring the CTP Series device. Connection to the console port through the USB connectors is possible only on the PP833 processor.

NOTE: The interface modules, clock module, power supply, Ethernet connection, and USB connectors for console connection are found on the rear panel in PP310 and PP332 processors.

CTP2000 Compression Interface Module

The CTP2000 Series compression interface module enables serial data and voice bundles to be compressed and passed through a CTP2000 platform. (See Figure 12 on page 10.)

Voice bundles originating from the CTP2000 IM-8P-T1/E1, analog CTP2000 IM-4WE&M, IM-2WFXS, and IM-2WFXO modules use the CTP2000 compression module to compress the voice bundle. Voice bundles ranging from 1–24 channels on a T1 module, 1–30 channels on an E1 module, and 1–8 channels on a 4WE&M module can be bundled and connected through the compression module to compress the voice bundle and build the IP packet.

CTP2000 4WE&M Interface Module

The CTP2000 Series 4WE&M interface module has eight 4-wire E&M ports and provides support for voice applications. It is used with voice compression (VCOMP) bundles in CTP2000 models and can be used only with a CTP2000 compression module.

Four-wire audio interfaces with E and M signaling interfaces (4WE&M) are commonly used as trunks between a central office (CO) and a private branch exchange (PBX). E and M is a type of supervisory line signaling that uses separate leads, called the "E" (ear) lead and "M" (mouth) lead and are traditionally used in the telecommunications industry. In 4WE&M signaling, two wires are used to receive and two wires are used to transmit, incorporating simplex control and differential payload in each channel. Type I, II, and V signaling is supported.

The 4WE&M interface module consists of a front card and a rear transition module (RTM). Port interfaces are located on connectors A and B of the RTM. (See Figure 13 on page 12 and Figure 14 on page 12.) The RJ-45 connectors are not used.

Figure 13: CTP2000 4WE&M Module

Figure 14: 4WE&M RTM

CAUTION: Power to the RTM is supplied from the interface module. Using an RTM other than those matched to the interface module may result in damage to both the interface module and the RTM. For example, never install a clock module RTM directly behind a 4WE&M interface module.

Voice ports can be used only by voice compression bundles (VCOMP) and cannot be used for CTP, SAToP, or CESoPSN bundles. There is no software configuration of 4WE&M ports. Signaling type is configured by means of jumpers (see Figure 16 on page 13 and

Table 3 on page 13). One or more 4WE&M ports can be mapped to a VCOMP bundle. The bundle configuration specifies the remote destination, the local port or ports transported by the bundle, voice compression options, as well as other configuration options.

NOTE: Jumper JP17 must be in Position 1-2 (see Table 3 on page 13) if any ports are set for Type II signaling. This jumper ties all signal battery (SB) signals to battery voltage (-48V).

Jumper JP26 is used to connect all signal grounds (SG) to the chassis ground. When jumper JP26 is in Position 1-2, the signal ground is connected to the chassis ground. In Position 2-3, it is isolated from the chassis ground.

The rear transition board uses two RJ-21 25-pair Telco connectors labeled A and B to interface the audio and control connections for eight E&M channels.

NOTE: Because of space limitations, a 180° RJ-21 connector is required. The CTP 4WE&M RTM supports clips to secure the RJ-21 cable connections to the RTM.

The R1/T1 pair and the R/T pair are the audio inputs and outputs of each port, respectively. For example, the audio input pair for port 0 is R1 and T1 on pins 2 and 27 of connector, The audio output pair for port 0 is R and T on pins 1 and 26.

See Table 4 on page 15 for signal definitions. See "CTP2000 4WE&M Interface Connector Pinouts" on page 41 for the connector A and B pinouts.

Supervisory Signaling

Supervisory signaling is the means by which a telephone user requests a service or initiates a call. The signaling unit (CTP platform) interacts with the trunk unit (PBX) by means of either two or four leads, depending on the signaling type. (See Figure 17 on page 16.) The signaling unit controls the E lead, whereas the trunk side controls the M lead. The two signaling states are on-hook and off-hook. During inactivity both units are on-hook. See Table 5 on page 17 for a summary of signaling types supported by the CTP2000 4WE&M module.

    end

Type I uses two leads—the E and M leads—for signaling. During inactivity, the E lead is open and the M-lead is connected to ground. The CTP device connects the E lead to a grounding point to signal off-hook, and the PBX connects the M lead to the battery (-48 V) to signal off-hook. Note that two signaling units cannot be connected back-to-back. With type I signaling, the signaling and trunk units must be connected by means of a common ground. Because the two sides are not isolated, they are susceptible to noise in the audio channels.

Type II uses four leads—E, SG, M, and SB—for signaling. During inactivity, both the E and M leads are open. To signal off-hook, the PBX connects the M lead to SB and the CTP device connects the E lead to SG. Note that two signaling units can be connected back-to-back if the appropriate signaling leads are swapped. With Type II signaling, the signaling unit and the trunk do not share a common ground.

Type V uses two leads, the E and M leads, for signaling. During inactivity, both the E and M leads are open. The CTP device signals off-hook by connecting the E lead to ground. The trunk circuit signals off-hook by connecting the M lead to ground. As with type I, with type V signaling, the two units share a common ground. Type V signaling allows for signaling units to be connected back-to-back.

CTP2000 2W-FXS and 2W-FXO Interface Modules

The CTP2000 2W-FXS and CTP2000 2W-FXO interface modules provide analog support for voice applications. The 2W-FXS module has 24 two-wire FXS ports and the 2W-FXO interface module has 12 two-wire FXS ports. Both are paired with an RTM.

• FXS interfaces point to the subscriber and supply battery and ring voltage. Some FXS devices also provide dial tone, but CTP FXS interfaces do not. FXS interfaces detect when the attached FXO interface goes off-hook and on-hook. An FXS interface is a two-wire interface; the leads are called the tip (T) and the ring (R).
• FXO interfaces point to the central office. An analog phone is an example of an FXO device. The FXO interface must detect ring voltage (the analog phone rings) and provide on- and off-hook indication to the FXS interface. An FXO interface is a two-wire interface; the leads are called the tip (T) and the ring (R).

Both interface modules consist of a front module and an RTM. See Figure 18 on page 18 and Figure 19 on page 18 for the CTP2000 2W-FXS interface module.

Both modules use connector A on the RTM. For both modules, connector B and the RJ-45 connectors are not used. See "CTP2000 FXS and FXO Interface Module Cables and Pinouts" on page 43 for connector pinout information.

You set the signaling by using the software on both modules. You cannot reconfigure the jumper parameters.

Required Cables and Pinouts

The CTP2000 2W-FXS and 2W-FXO interface modules require the use of double-shielded cables (copper braid plus aluminum mylar foil) to ensure EMI compliance. See "CTP2000 FXS and FXO Interface Module Cables and Pinouts" on page 43 for particulars about cable pinouts.

Analog FXS/FXO Loop-Start Signaling

There are two basic signaling protocols for FXS/FXO interfaces: loop-start and ground-start. Residential telephones use loop-start. Ground-start is typically used between a CO and a PBX to prevent "glare." Glare occurs when a call is established by the FXS device and the FXO device tries to make a call before the ring has been detected

When a call is initiated from the CO (or FXS) side, the FXS interface puts an AC ring voltage on the R lead (typically 70-90 Vrms). This ring voltage generates the ringing that you hear on an analog phone. When the FXO device answers the call (someone picks up the handset), the switch is closed between the T and R leads to complete a loop between the battery and ground in the FXS device. The FXS device detects the current, which flows from the battery (-48 V) through the R leads and back through the T leads to ground and stops the ring voltage.

When a call is initiated by the CPE (or FXO) device, the device goes off-hook, closing the connection between the T and R leads. The FXS device senses the current flow in the loop. Either the attached FXS device, or an upstream FXS device, provides dial tone to the FXO device after it is ready to accept the digits for the call destination. Providing dial tone is a form of start-dial supervision.

On the FXO device, when the device is on-hook, there is an open lead between the T and R leads. When the device is off-hook, the T and R leads are shorted with a typical load of \~300 Ohms. With loop-start, the T and R leads on the FXO interface can be switched without adversely affecting the signaling.

Glare occurs when a call is established by the FXS device and the FXO tries to make a call before the ring has been detected. Because it takes time for the FXO device (or person about to place a call) to detect ringing, it is possible for the FXS and FXO devices to bot seize the line without knowledge that the other end has done so. Ground-start circuits were established the minimize the possibility of glare. See “Analog FXS/FXO Ground-Start Signaling” on page 19.

Answer Supervision

Answer supervision is a signal used by the phone companies to determine when to start billing the originator of the call. Without answer supervision, you could get billed for the time the phone was ringing, even if the call was never picked up. When the FXS device has detected that the FXO device has gone off-hook, it reverses the polarity between the T and R leads for the duration of the call.

Disconnect Supervision

Disconnect supervision is a signal sent by the FXS device to the FXO device to indicate that the call has ended. The disconnect supervision signal can be either a battery reversal, battery denial (more than 350 ms), or a tone.

Note that loop-start circuits are not sensitive to tip/ring reversal. For example, the tip on the FXO device may be connected to either the tip or ring on the FXS.

Analog FXS/FXO Ground-Start Signaling

Ground-start signaling is used to minimize the potential for glare. Unlike loop-start circuits, ground-start circuits operate correctly only when the FXO tip is connected to the FXS tip and the FXO ring is connected to the FXS ring. Also, unlike loop-start circuits, the FXS and FXO grounds must be at the same potential.

When on-hook, the FXO ring is not connected to either the tip or ground. Likewise, when idle, the FXS tip is not connected to ground. When a call is initiated from the CO (FXS

side), the FXS grounds its tip and applies an AC ring voltage to the R lead. The FXO devi senses the grounded tip and AC ring voltage, and then goes off-hook by closing the loop (connecting R to T). The FXO has 100 ms to respond to the grounded tip/ring voltage. This time constraint is used to minimize glare. Once the FXO has closed the loop, the call proceeds as in the loop-start case.

When a call is initiated by the customer (FXO) side, the FXO starts by grounding the R lead. The FXS side responds by grounding its T lead. After the FXO has detected the grounded T lead, it closes the loop by removing the R lead from ground and closing the loop. With ground-start circuits, a far-end disconnect (FXS side) is indicated by the FXS disconnecting the tip from ground. The FXO senses the tip disconnect and goes on-hook by opening the loop.

Digital Signaling

Channel banks are often used to multiplex and demultiplex FXS or FXO interfaces onto T1 or E1 digital circuits. In the process, the analog signal is converted into pulse code modulation (PCM) and carried by one of the channels in the time-division multiplexing (TDM) circuit. For the interface to function properly, it must be able to signal the remote end of the T1/E1 connection as well as respond to signals from the remote end. Signaling is carried over the TDM circuit using either channel-associated signaling (CAS) or common-channel signaling (CCS). Generally, four signaling bits (A, B, C, and D) may be used; however, two signaling bits are most common (A and B).

For CTP analog voice products to work with digital devices, A and B bits are generated and transported across the network.

Digital FXS/FXO Loop-Start Signaling

For loop-start signaling of FXS and FXO interfaces, the A bit is used to indicate the state of the current loop, whereas the B bit is used for ringing. In the idle state (no ringing, FXO on-hook), A=0 and B=1. A=1 when the FXO is off-hook. Ringing is signaled by the B bit toggling between 0 and 1. Typically the toggling is 2 seconds off and 4 seconds on. For digital loop-state, the signaling is bidirectional.

Because hook indication is detected by the analog FXS interface, this device is responsible for generating the A bit. Likewise, because the analog FXS interface generates the ring voltage, this device must respond to the B bit. Because the signaling is bidirectional, the FXS side must echo the B bit when sending out the A bit.

The same logic applies to the FXO interface. The FXO device goes on/off-hook. It must respond to the A bit, going off-hook when A transitions from 0 to 1, and going on-hook when A goes from 1 to 0. The analog FXO interface detects ringing; therefore, it is responsible for generating the B bit value. The FXO device must echo the A value when sending out the digital signaling over the network.

Two situations for this call sequence must be considered: when the CTP is the FXO device and when the CTP platform is the FXS device. In both cases, before the call starts, the FXO is on-hook (A=1) and there is no ringing (B=1).

- For an analog CTP FXS interface, before the call starts, the CTP interface must generate A=0 and send both A=0 and B=1. When the call initiates from the CO, the B bit is

toggled. In response to this toggling, the CTP device generates a ring voltage on the analog FXS interface. When the attached FXO device goes off-hook, the CTP FXS interface detects the off-hook, sets the A bit to 1, and stops the ring voltage. During the call, the CTP device sends A = B = 1 signaling bits. At the end of the call, the FXO de goes back to on-hook, the CTP detects the on-hook, sends out A=0 and B=1 signaling bits, and the circuit returns to the idle state.

- For an analog CTP FXO interface, before the call starts the FXO is on-hook and no ringing is generated by the attached FXS device. In this, the idle state, the CTP interface generates B=1 and sends both A=0 and B=1. When the call comes in from the CO, the CTP FXO interface detects ring voltage and starts toggling the B bit. When the other end of the VCOMP bundle goes off-hook, it sends A=1 to the CTP. In response, the CTP FXO interface closes the loop, going off-hook. With ringing stopped, the CTP interface sends A = B = 1 during the call. At the end of the call the interface is again idle, and CTP interface sends A=0 and B=1 signaling bits.

Digital FXS/FXO Ground-Start Signaling

Unlike loop-start interfaces, in which the FXO and FXS each separately control a single signaling bit, with ground-start signaling each side controls both the A and B bits. We must consider each interface when the call is initiated by either interface. (See

Table 6 on page 21, Table 7 on page 21, Table 8 on page 22, and Table 9 on page 22). In all cases, when the FXO/FXS interface is idle, the FXO interface generates A = B = 1 signaling bits and the FXS A = 0, B = 1. When a call is in progress, either side initiates a call termination if it receives these signaling bits. For example, an FXS goes on-hook if it receives A=B=1 signaling bits.

CTP2000 8P-IRIG Interface Module

The CTP2000 8P-IRIG interface module enables an interrange instrumentation group time code (IRIG-B) signal to be transported through an IP network. IRIG-B is a special time code transmission format that uses a hybrid analog/digital physical interface. The IRIG-B standard consists of a family of rate-scaled serial time codes with formats containing up to three coded expressions or words. The IRIG-B pulse code contains one frame of 100 elements per second for the time of the year and GPS receiver status. IRIG-B encodes day of year, hour, minute, and second data on a 1-KHz carrier frequency, with an update rate of once per second.

The CTP2000 8P-IRIG module has eight ports. You can configure direction, high and low level output, and data range for this module. (See Figure 22 on page 23.)

CTP2000 Clock Interface Modules

Clock interface modules provide clock distribution between modules when the backplane is in use by voice applications.

The clock rear transition module (RTM) is used to input a reference clock into the CTP2000 platform. The clock RTM is installed in the rear of the chassis behind the first interface module as follows:

• On CTP2008 devices, the first slot above the processor RTM.
• On the CTP2024 and CTP2056 devices, the first slot below the processor RTM.

Clock distribution is accomplished through a "hub-and-spoke" configuration composed of a main module and a spoke module. Clock main modules (Figure 23 on page 24) and

clock spoke modules (Figure 24 on page 24) allow more clock input types in the CTP2000 chassis and provide the capability for clock distribution when both serial or T1/E1 interface modules and voice modules are installed in the same CTP2000 chassis.

Figure 23: Clock Main Module

Figure 24: Clock Spoke Module

The clock main module accepts an external clock reference and distributes it to the spoke module using a twisted pair cable. Each nonvoice card receives the clock on the first RJ-45 and sends it to the front module.

The main clock module has two BNC inputs (BITS and TTL), six RJ-45 ports, and one DB-25 port. Each RJ-45 port can be connected to one spoke module. The spoke module has one ingress RJ-45 port and one DB-25 interface. (See Figure 23 on page 24, Figure 24 on page 24, and Figure 25 on page 24.)

NOTE: BITS input is a T1/E1 line interface unit (LIU), with AMI (alternate mark inversion) encoding enabled and B8ZS/HDB3 (Zero Suppression) disabled. The equalization is set for a 0-133 feet cable. An internal 100 ohm termination is present, although it might need to be externally augmented based on the type of cabling used. Any valid AMI signal works properly and it is not restricted to only the "all 1" BITS signal but the ones density must be sufficient to prevent LOS (according to the ITU G.775 recommendation). The TTL input has a slice point of 3.3V/2 = 1.65V relative to chassis ground (GND). Therefore, any signal on the coaxial center conductor that transitions through that voltage registers a transition. There are many signals, besides TTL, that satisfy this criteria. An external termination must be provided that matches the impedance of the cable that goes to the BNC connector.

If you can configure the rate in CTP menu, then the TTL supports a frequency of 2048 KHz for the TTL clock input, provided the signal is good and noise-free (terminated properly). TTL is rate-agile, while BITS is restricted to T1/E1 frequencies.

The TTL input is high-impedance (no on-board termination provided) because a variety of cable types might exist that you can use to drive signal to this connector, such as RG-58 coax (50 ohm), RG-59 coax (75 ohm), or twisted pair (100-120 ohm). Instead of applying a particular impedance termination on the board and have it incorrectly done, we recommend that you configure the impedance termination based on your network environment. For example, a 50 ohm termination is needed if you are using RG-58/U coax cable, which has 50 ohm impedance.

External Reference Clock

The CTP2000 device can receive the external reference clock from any of the following inputs on the clock main module:

• The DB-25 connector. The clock input is provided on pins 24 and 11.
  • The T1/E1 BITS inputs
  • The T1/E1 TTL input

Installation Notes for Clock Interface Modules

• Main modules and spoke modules are not hot-swappable.
  • Nonvoice modules and voice modules can be installed in any slot.

• Main clock RTMs must be installed in slot 0 behind either a serial module or a T1/E1 module.

• Spoke RTMs must be installed behind serial modules and the lowest-numbered T1/E1 slot.
• If a T1/E1 module is installed in the slot that is closest to the processor, a spoke RTM is not needed behind any T1/E1 modules. They will synchronize to the H.100 clock.
• For platforms with only nonvoice boards (serial or T1/E1 module), only a main RTM is needed for external clock reference input.

NOTE: The clock RTM is installed in the rear of slot 0 next to the CPU slot. When you upgrade from an older processor to a PP833 processor, you can leave the CPU RTM in the chassis. Leaving the CPU RTM in the chassis will not adversely affect the functioning of the PP833 processor but will also not provide any functional value.

• ANSI T1.646-1995 Telecommunications – Broadband ISDN - Physical Layer Specification for User-Network Interfaces Including DS1/ATM (1995)
• Ensure that power cables deliver sufficient power to the device.
• Attach laser fiber connectors only to Class 1 laser devices in accordance with IEC 60825-1, Safety of Laser Products - Part 1.
• Route cables so that they do not restrict ventilation or airflow.
• Route cables so that modules and field-replaceable units are easily accessible.
• Route cables in a logical direction to prevent loss of connectivity to other equipment in the rack, associated equipment in adjacent racks, or to the backbone network.
• Consider using cable-management brackets to keep network cables untangled and orderly and to prevent cables from hindering access to other slots.

CTP2000 Series Console Cable Pinouts

CTP2008, CTP2024, and CTP2056 devices with the new PP833 processor use a USB connector. The USB port on the device is connected to an RS-232 serial cable using a USB connector. The RS-232 cable is then connected to the console using an RJ-45 connector. CTP2000 series devices with the PP310 and PP332 processors use an RJ-45 connected to the COM2 port. This cable must be connected during the first boot process. Use a shielded cable for the COM2 port on the CTP2056 device. Figure 27 on page 47 displays the console cable pin configurations for CTP2000 series devices with the PP310 and PP332 processors. On the left is the RJ-45 connector, and on the right is the DB-9 connector with the pin numbering indicated.

The console connections are configured to the following parameters:

• Speed: 9600 bps
• Data bits: 8
• Stop bits: 1
• Flow control: Xon/Xoff
• Parity: none

Protecting CTP2000 Modules and Slots

To prevent damage from electrostatic discharge, wear an antistatic wrist strap, and connect it to one of the jacks when handling components. The CTP2056 has an ESD (electrostatic discharge) grounding jack located in the rear lower-left corner of the chassis near the power switch. There are no ESD jacks on the other CTP2000 platforms, so you must use another grounding device.

To protect the modules, components, and slots when installing components, observe the following guidelines:

CAUTION: When handling components, use an antistatic wrist strap connected to one of the device's ESD grounding jacks or to another grounding device. This action helps to protect the module from damage by electrostatic discharge.

CAUTION: Always handle a module by its edges. Do not touch the components, pins, leads, or solder connections.

CAUTION: If you meet strong resistance when attempting to seat a module using the ejectors, remove it from the chassis and confirm that the slot is designed to hold the module. Also, be sure that you have aligned the left and right edges in the correct matching module guides.

CAUTION: Be sure to cover every empty slot with a blank filler panel to protect the device from dust or other foreign substances and to ensure proper device cooling.

CAUTION: Do not discard the antistatic bag. When a module is not in use, store it in an antistatic bag.

Upgrading CTP2000 Series Components for Memory Upgrades

Certain CTP2000 Series components need to be upgraded when RAM memory is increased, as required by certain JUNOS version updates. The affected modules and other components can be:

• Processor module that contains the RAM card
• CompactFlash card
• Rear transition module (RTM) in case of the PP310 and PP332 processors

To install a CTP module:

1. Ground yourself by using an antistatic wrist strap or other device, and connect it to one of the ESD grounding jacks, if available, or another grounding device.
2. Choose the slot where you want to insert the module.
3. With a Phillips screwdriver, loosen the screws that secure the blank filler panel covering the empty chassis slot, if present, and remove the filler panel.
4. Remove the module from its antistatic bag, being careful not to touch module components, pins, leads, or solder connections.
5. Verify that the ejectors are in the open position (facing outward).
6. Guide the module into the chassis by placing it between the guides of the selected slot and pushing the module until it stops.

The module stops sliding when the ejectors make contact with the chassis.

CAUTION: If you meet strong resistance when attempting to seat the module using the ejectors, remove it from the chassis, and confirm that the slot is designed to hold the component. Also, be sure that you have aligned the left and right edges in the correct matching tracks.

1. Insert the module into the midplane by simultaneously pressing both ejectors inward and exerting forward pressure on the module. The small red release buttons should click into place.

2. Tighten the module's captive screws using a Phillips screwdriver.

NOTE: Tighten the captive screws completely before installing an adjacent module so that proper electromagnetic interference (EMI) gasket compression occurs. Failure to do this can make it difficult to install adjacent modules.

Returning CTP Products for Repair or Replacement

In the event of a hardware failure, please contact Juniper Networks to obtain a Return Material Authorization (RMA) number. This number is necessary to ensure proper tracking and handling of returned material at the factory. Do not return any hardware until you

have received an RMA. Juniper Networks reserves the right to refuse shipments that do not have an RMA. Refused shipments are returned to the shipper through collect freight.

If possible, use the original shipping crate, pallet, and packing materials in which the chassis was originally shipped. If these materials are unavailable, use comparable shipping material, or contact your Juniper Networks representative for information about approved packaging material.

See the customer support Web page for complete repair and return policies and procedures.

To pack the chassis for shipment:

1. Ground yourself by using an antistatic wrist strap or other device.
2. Issue the proper shutdown commands to halt your system.
3. Switch all power switches to the OFF position.
4. Remove all cables from the chassis.
5. Remove all major components from the chassis, including interface modules, processor modules, RTMs, and fan trays.
6. Remove the chassis from the rack and bolt it to the shipping pallet.
7. Cover the chassis with an ESD bag and place packing foam on top of and around the chassis.
8. Place the crate cover over the chassis and fasten the cover to the pallet.
