Frequently Asked Questions - LBH600A-P-12 Black Box

What is the operating temperature range for the LBH600A-P-12?

The Extreme version (P) operates from -40°C to 75°C (long term) and can withstand short-term exposure from -50°C to 100°C. Ensure the unit is protected from direct rain when used outdoors.

Does the LBH600A-P-12 have auto-MDIX on all ports?

Yes, all six RJ-45 ports support auto-MDIX (auto-cross) in auto-negotiation mode, so you can use standard straight-through cables to connect to other switches, hubs, or devices.

What power options are available for this switch?

The switch can be powered via an external AC adapter (included) that outputs 12 VDC, or by direct DC input (8-15 VDC) through the built-in terminal block. For redundancy, both can be connected simultaneously.

How do I mount the LBH600A-P-12?

It can be mounted using the included metal panel-mounting clips, on a DIN rail (using optional bracket Model DIN_RAIL_MC2), or in a 19-inch rack using the optional LH1505-RACK tray.

What does the Alarm Contact do?

The two-pole terminal block provides a normally closed (NC) relay contact that opens when internal power is lost (external power failure or internal supply failure). It allows remote monitoring of the switch's power status.

Can I use fiber optic cables with this model?

No, the LBH600A-P-12 has only copper RJ-45 ports. For fiber connectivity, consider models like LBH150A-P or LBH240A-P which include one or two 100BASE-FX fiber ports.

What is the maximum cable length for 100BASE-TX?

The maximum segment length for 100BASE-TX (Category 5e or better UTP) is 100 meters (328 feet). For 10BASE-T, you may use Category 3 cable up to 100 meters.

Is this switch plug-and-play?

Yes, it is unmanaged and operates as a plug-and-play device. There is no software configuration needed. It automatically learns MAC addresses and negotiates speed/duplex with connected devices.

What are the LED indicators telling me?

The LEDs include: PWR (green) for power; 10/100 per port: on for 100 Mbps, off for 10 Mbps; LK/ACT per port: steady for link, blinking for activity.

Where can I download the full user manual?

The full user manual (PDF) can be downloaded from notice-facile.com or the Black Box website at www.blackbox.com. The manual provides detailed installation, operation, and troubleshooting information.

Mounting options include panel-mounting, DIN-rail, or rack-mount tray. Choices of models for external AC or internal DC power are available. Ambient operating temperature is between -40^ to +75^ depending on the power source used. Storage temperature rating is between -40^ to +85^ .

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

All the Extreme and hardened models also come along with hardware operated Alarm terminal block for providing extra reliability to the unit. The Alarm feature allows the LBHXXX heavy duty users to be aware and to monitor any internal power failure. See section 44 for details.

The front side of the unit has four/five twisted-pair 10/100Mb switch ports and one/two 100Mb fiber port. All the RJ-45 ports of the Heavy-Duty LBHXXX Edge switches support auto-cross (MDIX) operation under auto-negotiation mode. The Heavy-Duty LBHXXX provides switching among four 10/100 auto-negotiating copper ports and two 100Mb fiber ports which may be SC, ST, MTRJ or LC multi-mode or single-mode. The LBHXXX's breadth of fiber options and well as temperature options provide many networking options and solutions in a very small footprint.

Two sets of LEDs to indicating the operating status of ports are mounted on the top and front (for extra viewing advantage while rack-mounted). For each port, there are Link and Activity (LK/ACT) LED's on the top indicating that the media cables are

Fig 2.2c

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

connected correctly and showing, by blinking, when there is traffic. The LK/ACT LED's are repeated on the front as 1 (port 1)...6 (port 6), whereas on the side as LA1...LA6. There is another set of LEDs on the front for 10 or H and 100 or F, to indicate the data rate as well as a set to indicate duplex for ports 1 and 2 only. 10/100 indicates the speed for copper ports, whereas F/H indicates Full and Half duplex for fiber ports only.

There is a power (PWR) LED to indicate that the unit is turned ON. The fiber ports on the LBHXXX Edge switches are multi-mode or single-mode with an SC, ST or small form factor connector (MTRJ multi mode or LC single-mode).

The external DC power plug connector and/or "jack" and the internal DC input terminal is provided on the rear of the unit.

2.3 Frame Buffering and Latency

The Heavy-Duty LBHXXX Series Edge Switches are store-and-forward switches. Each frame (or packet) is loaded into the Switch's memory and inspected before forwarding can occur. This technique ensures that all forwarded frames are of a valid

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

length and have the correct CRC, i.e. they are good packets. This eliminates propagation of bad packets, enabling all of the available bandwidth to be used for valid information.

While other switching technologies such as "cut-through" or "express" impose minimal frame latency, they will also permit bad frames to propagate to the Ethernet network. The "cut-through" technique permits collision fragment frames, which are a result of late collisions, to be forwarded--which add to the network traffic. There is no way to filter frames with a bad CRC (the entire frame must be present in order for CRC to be calculated). Since collisions and bad packets are more likely when traffic is heavy, store-and-forward switch technology enables more bandwidth to be available for good packets when the traffic load is greatest.

To minimize the possibility of dropping frames on congested ports, each Heavy-Duty LBHXXX Edge Switch dynamically allocates buffer space from 128KB memory pool, ensuring that heavily used ports receive very large buffer space for packet storage.

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

(Many other switches have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed number of packets to be stored per port. When the port buffer fills up, dropped packets result.) This dynamic buffer allocation provides the capability for the maximum resources of the Heavy-Duty LBHXXX Edge Switches unit to be applied to all traffic loads, even when the traffic activity is unbalanced across the ports. Since the traffic on an operating network is constantly varying in packet density per port and in aggregate density, the Heavy-Duty LBHXXX Edge Switches are constantly adapting internally to provide maximum network performance with the least dropped packets.

When the Switch detects that its free buffer queue space is low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices sending packets to cause "flow control". This tells the sending devices to temporarily stop sending traffic, which allows a traffic catch-up to occur without dropping packets. Then, normal packet buffering and processing resumes. This flow-control sequence occurs in a small fraction of a second and is transparent to an observer.

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

Another feature implemented in Heavy-Duty LBHXXX Edge Switches is a collision-based flow-control mechanism (when operating at half-duplex only). When the Switch detects that its free buffer queue space is low, the Switch prevents more frames from entering by forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.

The latency (the time the frame spends in the Switch before it is sent along or forwarded to its destination) of the Heavy-Duty LBHXXX Edge Switches varies with the port-speed types. The length of the frame is a variable as it is with all store-and-forward switches. For 10 Mb-to-10 Mb, 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the latency is 15 microseconds plus the packet time of 10 Mb. For 100Mb-to-100Mb forwarding, the latency is 5 microseconds plus the packet time of 100Mb.

side of the unit and is equipped with three (3) screw-down lead posts. The power terminals are identified as positive (+) and negative (-), and they are floating inside the unit so that either of the terminals may be grounded by the user if desired. The chassis is "earth" or ground (GND). The connection procedure is straightforward. Simply insert the DC leads to

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

the LBIIXXXXA(E)-II's power terminals, positive (+) and negative (-) screws. The use of Ground (GND) optional; it connects to the Edge Switch chassis. Ensure that each lead is securely tightened from the top, as shown on above picture with arrow.

NOTE: Always use a voltmeter to measure the voltage of the incoming power supply and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead will connect to the post labeled “+ve” and the rest to the “-ve”.

The GND can be hooked up at the last.

When power is applied, the green PWR LED will illuminate.

3.8 Connecting Ethernet Media

The Black Box LBHXXX-Series Edge Switches can be connected to two media types i.e. fiber and copper (RJ-45) types, runt at 100BASE-TX, 10BASE-T and 100BASE-FX only. CAT 5 cables should be used when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be used. In either case, the maximum

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

distance for unshielded twisted pair cabling is 100 meters (328 ft). For fiber port 10BASE-FL or 100BASE-FX multi-mode, 50/125 or 62.5/125 microns cabling can be used, whereas for single-mode, 9/125 microns cabling should be used. Fiber cabling supports much longer cable distance and higher bandwidths as compared to copper wiring.

The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted pair cables.

1. Using standard twisted pair media, insert either end of the cable with a RJ-45 plug into the RJ-45 connector of the port. Note that, even though the connector is shielded, either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be illuminated when the unit is powered and proper connection is established. If this does not help, ensure that the cable is connected properly and that the device on the other end is powered and is not defective.
4. All the RJ-45 ports are AUTO-Cross (MDIX), and will automatically determined the Link, while linking to another hub or Switch.

3.8.2 Connecting Fiber Optic ST-type, "twist-lock"

The following procedure applies to installations using ST-type fiber connectors. This procedure applies to ports using multi-mode ST fiber connectors.

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

1. Before connecting the fiber optic cable, remove the protective dust caps from the tips of the fiber connectors. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue dampened in alcohol. Make certain the connectors are clean before connecting. Note: One strand of the duplex fiber optic cable is coded using color bands at regular intervals; you must use the color-coded strand on the associated ports at each end of the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the Black Box Fiber port to the Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post) to the Transmit (TX) port of the remote device. Use the non-color coded fiber strand for this.
5. The LINK LED on the front of the fiber connector will illuminate when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit after cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the fiber connector to remedy this situation.

3.8.3 Connecting Fiber Optic SC-type , "Snap-In"

The following procedure applies to installations using SC-type fiber connectors, i.e., using multi-mode SC and SC single-mode. While connecting

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

fiber media to SC connectors, simply snap on the two square male connectors into the SC female jacks of the Fiber connector until it clicks and secures.

3.8.4 Connecting Single-MoHiber Optic

When using single-mode fiber cable, be sure to use single-mode fiber port connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx are the diameters of the core and the core plus the cladding respectively). Single-mode fiber allows full bandwidth at longer distances, about 20Km with the multi-mode SC.

The same procedures as for multi-mode fiber apply to single-mode fiber connectors. Follow the steps listed in Section 3.8.2 above.

3.8.5 Power Budget Calculations

for Heavy-Duty LBHXXX, Fiber Media

Receiver Sensitivity and Transmitter Power are the parameters necessary to compute the power budget. To calculate the power budget of different fiber media installations using Black Box products, the following equations should be used:

OPB (Optical Power Budget) = P_1 (min) - P_R (min)

where P_T = Transmitter Output Power, and P_R = Receiver Sensitivity

Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)

Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km] where the "Cable Loss" for 62.5/125 and 50/125μm (m.m.) is 2.8 dB/km, and the "Cable Loss" for 100/140 (Multi-mode) is 3.3 dB/km,

and the "Cable Loss" for 9/125 (Single-mode) is 0.5 dB/km and the "Cable Loss" for 9/125 (Single-mode) is 0.25 dB/km (SSCX)

The following data has been collected from component manufacturer's (Agilent's, JDS-Uniphase, stratus, Lucents') web sites and catalogs to provide guidance to network integrators and installers-

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed over long distances (i.e., over approx. 400 meters) can be achieved only if the following factors are both applied:

• The 100Mb fiber segment must operate in full-duplex (FDX) mode, and
• The worst-case OPB of the fiber link must be greater than the fiber cable's passive Attenuation.

(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

3.8.6 Connections to NICs

which support Auto-Negotiation, RJ-45 ports

The copper ports of Black Box LBH1XXX-Series Edge Switches will function properly with NICs (Network Interface Cards) which support Auto-Negotiation, and the Fast Link Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to the LBH1XXX-Series, it may be necessary to reload the NIC drivers on the user device if the NIC has been communicating with a protocol other than 100BASE-TX (such as 10BASE-T). When 100Mb operation is agreed and in use, the 10/100 LED is illuminated steady ON and is OFF, if 10 Mbps traffic.

4.0 OPERATION

4.1 Dual-Speed Functionality, and Switching

The Black Box Heavy-Duty LBHXXX Edge Switches provide SIX switched ports with combination of fiber and copper or copper only. The architecture supports a dual speed switching environment, with standard auto-negotiation capability.

The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and speed, and auto-cross for plug polarity. (See Section 4.2). When the connected device is 10 Mbps, the LBHXXXs obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps users can “communicate” with 100Mbps users as well as other 10 Mbps users through the switch. Similarly, the 100Mbps traffic obeys the rules of 100Mbps Ethernet, and can communicate with 10 Mb and 100Mb uscrs. Black Box Heavy-Duty LBHXXX units are plug-and-play devices. There is no software configuring to be done at installation or for maintenance, even for the LLL ports. The internal functions of both are described below.

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

Switching, Filtering and Forwarding

Each time a packet arrives on one of the switched ports, the decision is taken to either filter or to forward the packet. Packets whose source and destination addresses lie on the same port segment will be filtered, constraining them to one port and relieving the rest of the network from processing them. A packet whose destination address is on another port segment will be forwarded to the appropriate port, and will not be sent to the other ports where it is not needed. Packets needed for maintaining the operation of the network (such as occasional multi-cast packets) are forwarded to all ports. The Black Box Heavy-Duty LBHXXX Edge Switches operate in the store-and-forward switching mode, which eliminates bad packets and enables peak performance to be achieved when there is heavy traffic on the network.

Switching, Address Learning

The Black Box Heavy-Duty LBHXXX units have address table capacity of 2K node addresses, and are suitable for use in large networks. They are self-learning, so that as nodes are added or removed or moved from one segment to another, the LBHXXX- Series switch automatically keeps up with node locations.

An address-aging algorithm causes least-used addresses to fall out in favor of new frequently-used addresses. To reset the address buffer, cycle power down-and-up.

Black Box ^® Heavy Duty Edge Switches Installation and User Guide(07/05)

4.2 Auto-cross (MDIX),

Auto-negotiation and Speed-sensing

The RJ-45 ports independently support auto-cross (MDI or MDIX) in auto-negotiation mode and will work properly with all the other connected devices with RJ-45 port whether it supports Auto-negotiation or not (e.g 10Mb Hub) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch). No cross-over cable is required while using the LBHXXX's Auto-negotiation port to other devices. Operation is according to the IEEE 802.3u standard.

When a RJ-45 cable connection is made, and each time a LINK is enabled, auto-negotiation takes place. The Black Box Heavy-Duty LBHXXX advertises its capability for 10 or 100 Mbps speed and F/H duplex mode, and the device at the other end of the cable should similarly advertise / respond and both sides will agree to the speed and mode being used. Depending upon the device connected, this will result in agreement to operate at either 10 Mbps or 100Mbps speed, full- or half-duplex mode. Even a managed switch will connect at fixed mode (100Mb Full Duplex), the LBHXXX will connect at 100Mb Half duplex only. Since the Auto-negotiating LBHXXX will advertise the speed only and not look for the duplex mode set on the other side.

4.3 Dual LEDs, Front-panel and side-panel (Black Box Heavy-Duty LBHXXX)

LED Description

PWR Illuminates GREEN to indicate power applied.

LK/ ACT Steady ON for LINK w/no traffic, blinking for activity per port. LINK will turn off in the event connectivity is lost between the ends of the twisted pair segment or a loss of power occurs in the unit or remote device. The Link ports are also represented by LA1, LA2, LA3...LA6. (Steady On or steady Off indicates no Receive Activity).

10/100 Steady ON for 100Mb speed, OFF for 10Mb speed per port (copper ports) F/H (FH1, FH2) Steady ON for Full duplex (F/D) mode, OFF for Half duplex (H/D) mode per port (For fiber port only)

NOTE: The port#1 and 2 is being assigned for copper or fiber port for different models. On all copper 10/100 ports model (c.g LBHXXXA), the LEDs 10 or 100 denotes for copper port only. For the model 4copper +2 fiber or 5copper +1fiber.(e.g LBHXXXA(E)-H-xx-yy) the xx denotes for fiber port only.

4.4 Hardware operated Alarm Contact

for monitoring internal power supply

The two screws Alarm Contacts feature, standard on Black Box LBHXXXA(E)-H and P, provides Normally Closed (NC) contacts to which the user can attach one sets of status monitoring wires at the green terminal block. When this option is present, the terminal block for Alarm Contacts is part of the Power Input panel in the Black Box LBHXXXs case. The DC power input connection is in the same panel.

The NC Alarm Contact is held close when there is power on the

main board inside of the LBHXXX. This provides a "Hardware operated Alarm" because the NC contacts will open when internal power is lost, either from an external power down condition or by the failure of the power supply inside of the Black Box LBHXXX Switch.

Close-up of a black electronic device with green connectors and a small terminal labeled 'B-12V', no readable text or symbols beyond labels.

Useful info about Alarm Contacts in LBHXXXA(E)-II and LBHXXXA(E)-P:

1. Two-position terminal block (1,2) provided next to the DC power input, as shown above.
2. The Alarm Relay contact connected to the two terminals (1,2) is hardware operated.
3. By default it is NC (normally closed). It will open if there is any loss of power to the electronics inside of the unit.
