Special features for LB9007A-ST-R2, LB9007A-SC-R2, LB9012A-R2, LB9017A & LB9024A LB9007A-ST-R2, LB9007A-SC-R2, LB9012A-R2, LB9017A & LB9024A house a console port that enables connection to establish a VLAN (virtual local area network), port aggregation, the setting of half or full-duplex transmission, and the setting of 10Mbps or 100Mbps for TX transmission. For these features to operate through the console port, it is necessary to first configure in DOS or a terminal emulation program such as HyperTerminal. Setting up Console Port Connection To configure these features through the console port, it is necessary to first configure a terminal emulation program in DOS or in Windows such as HyperTerminal. • Check the switch, cables, and computers for proper installation before configuration. • Attach a PC or any VT100 compatible terminal to the console port on the back of the switch (see figure 6) using the following settings: Terminal type VT100 Port type (COM 1~4) Communication Mode 8 data bits, 1 stop bit, no parity and 9600bps (for initial configuration) Flow Control None Hardware Compression NA 23

TX ports: assigned to V1, auto-negotiation, and flow control ON. FX ports: assigned to V1, 100FX full-duplex, and flow control ON. The console port menu displays the current settings (i.e.: auto->100TX full) or, if the port is not connected, displays the message auto->No Link. Establishing a VLAN for LB9007A-ST-R2, LB9007A-SC-R2 & LB9012A Virtual Local Area Networks (VLANs) enable segmenting of the LAN without regards to physical location. Assign each port to a VLAN group or set of groups according to accessibility needs. Thus, a specific port could be in more than one VLAN group. There are 4 VLAN groups available for models specified here. The port numbers are designated alpha-numerically. The letters A, B, and C identify three slots from left to right and the ports are numbered 1 through 4. Therefore, the port # is a combination of the slot (A-C) and the position of the port in that section (1-4). LB9012A has 3 slots and LB9007A-SC/ST-R2 have 2 slots A & B only. Follow these steps to assign port(s) to a VLAN group. • Enter [V] from the Main Menu • Select a VLAN group: [V1], [V2], [V3], or [V4] • Enter the port #. Note: If entering more than one port to a VLAN group, separate each port # by commas without spaces or dashes. To enter an entire module, enter only the letter (A, B, or C). Only one VLAN group can be defined at a time. Repeat selecting VLAN groups and assigning ports until all ports are assigned to at least one VLAN group. Though each VLAN grouping does not need to be utilized, each port must be assigned to at least one VLAN group. Hit the [ESC] key when done. To return to the default settings (in which each port is assigned to V1), enter [D] from the main menu. A prompt appears to verify this action. VLAN Example: • Enter [V1] (no [ENTER]) • Key A1,B4,C2 Proceed with the assignment of the remainder of the ports into any VLAN grouping: • Enter [V2] (no [ENTER]) • Key A1,B1,B2,B3, • Enter [V3] (no [ENTER]) • Key A2, A3, A4 Note: Until assigned, the menu displays **error** for each unassigned port. While any port is in the **error** status, the [ESC] key will not return the screen to the main menu. Assign each port to a VLAN grouping prior to exiting program. View the results on the following illustration. 25 The current V1 is A1,A2,A3,A4,B1,B2,B3,B4, Please enter the new port list ->

Performing Port Aggregation The aggregation or trunking of ports enables an aggregate of bandwidth between like switches. Attaching the console port to a PC or any VT100 compatible unit launches a main menu screen displayed by hitting any key. The Escape key quits the program functions. The [T] command displays further parameters that define which ports or number of ports that can be in one trunk, or the number of possible trunks. The VLAN function might become disabled on trunked ports. Configure Port Settings The duplex mode and speed can be altered and the flow-control can be turned off to accommodate special needs. The port numbers are designated alpha-numerically. The letters A, B, and C identify the module slots from left to right and the ports are numbered 1 through 4. Therefore, the port # is a combination of the slot (A-C) and the position of the port in that slot (1-4). On the console port display screen, a description of the number of TX and FX ports (such as 1FX, 4TX) further identifies the module slots. Follow these steps to change the speed/duplex mode setting or to toggle flow control ON/OFF: • Enter [M] (no [ENTER]) • Select a port • Select the media from the list that appears on the screen Note: Only one port can be changed at a time.

Installation Quick Tip Install a Black Box Express Ethernet Switch as a plug-and-play device. No special configuration is required. Details below are consistent with the installation of any electronic device Place the Black Box Express Ethernet Switch where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements: • The room temperature should be between 32 and 104 degrees Fahrenheit (0 to 40 degrees Celsius). • The relative humidity should be less than 90 percent, non-condensing. • Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards for IEC 801-3, Level 2 (3V/M) field strength. • Make sure that the switch receives adequate ventilation. Do not block the ventilation holes on the side of the switch or the fan exhaust port on the rear of the switch. • The power outlet should be within 1.8 meters of the switch. Connecting to Power Connect the supplied AC power cord to the receptacle on the back of the switch, and then plug the cord into a standard AC outlet with a voltage range from 100 to 120 VAC. For external power supply units, plug the jack into the DC receptacle on the front of the unit, and plug the power supply unit into a 110 AC outlet. Turn the switch on by flipping the ON/OFF switch on the rear of the unit to the I (ON) position. The O position is OFF. Connecting to Your Network If you are making a connection to a server or workstation, be sure that it has a properly installed 100BASE-TX (or 100BASE-FX if the switch does not contain 100BASE-TX ports) network interface card. Connect the RX/TX jacks on the target device to the TX/RX jacks on the switch and the RJ-45 jacks on the target device to the RJ-45 jacks on the switch. Use the uplink port for connecting to a regular (i.e. non-uplink) port of a hub or another switch. If connecting to an uplink port of a hub or another switch, use any port. There is no uplink issue with fiber ports. Copper-based cabling Connect cables to computers or network segments into the RJ-45 ports on the front of the switch. The cable must be a Category 5 shielded twisted-pair or unshielded twisted-pair (STP/UTP) cable for 100BASE-TX, or Category 3, 4, or 5 STP/UTP cable for 10BASE-T. Consult Table 9 for further details. Fiber-optic cabling Prepare a pair of fiber optic cables with SC or ST type connectors at both ends. The cable for fiber ports must be a 62.5/125 micron fiber-optic cable for 100BASE-FX. Consult Table 9 for further details. Table 9: Cable Specifications Speed Connector Port Speed Half/Full Duplex Cable Range 100BASE-TX RJ-45 100/200 Mbps Category 5 UTP 100 meters 33

10BASE-T RJ-45 10/20 Mbps Category 3, 4, or 5 UTP 100 meters 100BASE-FX ST or SC 200 Mbps 62.5/125 micron fiber- optic cable 2 kilo-meters Uplink or MDI Function A network of switches connected (or cascaded) together via uplink ports is termed a “collapsed backbone.” The uplink function transforms the adjacent or indicated port into an uplink port with a push of the button or by sliding the switch. This allows connection to another switch or hub without preparing crossover cable. However, this is unnecessary when either connecting directly to the uplink port of another switch or hub or when connecting fiber ports between switches or hubs. 34

Trouble-shooting Guide This trouble-shooting guide describes problems that could occur with the Express Ethernet Switch. The guide states possible reasons for the problems, and possible steps to take to solve the problems. No Power to the Switch. Symptom: Power cord is connected to the switch, but all LEDs, including the Power LED, are off. Possible Problem Solution Loose power connection or faulty power supply 1. Check both ends of the power cord to make certain that they are securely connected to the power receptacle on the switch and to the power outlet. 2. Verify that the power outlet has power. No Connectivity to the Data Terminal Equipment. Symptom: An Ethernet switch cannot communicate to the directly connected computers or network segments. Possible Problem Solution Incorrect or faulty cabling 1. Check cables for a secure connection. 2. Verify that the correct type of cable is in use. • For connection to a PC or a network interface card (NIC), use a straight-through cable. • For uplink to another switch or hub, use a cross-wire cable, or use a regular straight-through cable connected to the uplink port with the uplink button activated. • Refer to Table 9 for cable specifications. 1. Verify proper cable preparation. 2. Use a time domain reflectometer (TDR) or other cable-checking device to verify that the cable has no opens, shorts, or other problems. 3. Swap the cable with another of the same kind to see if the cable is bad. • Replace or fix the faulty cable as necessary. Dysfunctional NIC on a PC or workstation Run the diagnostic supplied by the vendor on the NIC to determine if it is functioning properly. If it is not, replace it. Packet Overflow or Hardware problem Reset the switch by pressing the reset button or turn the switch off, then on again. No Connectivity to Certain Nodes on the Network Symptom: Data terminal equipment (DTE) connected to the switch can not send or receive information from certain segments on the same network or across to another LAN or WAN. Possible Problem Solution Hardware problem Check for a damaged RJ-45 jack, or fiber SC or ST type connector. 35

Transmission Problems Symptom: Connections across a LAN switch are slow or unreliable. Possible Problem Solution Incorrect full- or half-duplex settings Express Ethernet Switches are all equipped with auto-negotiation to communicate with other DTEs on the network for the best available performance. 1. Verify if the connected NIC is equipped with auto-negotiation (this is not the same as auto-sensing). 2. Change the DIP switch setting if available. Exceeded cabling distance or misused cable 1. Ensure that the proper cable is in use and that the recommended distance is not exceeded. For information, refer to Table 9. 2. Check the cable distance using a cable tester or TDR. Verify that the cable lengths attached to the switch meet Ethernet/IEEE 802.3 specifications. 3. If the distance is out of specification, reduce the length of the cable or add a repeater, ensuring no more than four repeaters are attached. Bad adapter in attached device Check the switch port statistics. If excessive errors are found, run the adapter card diagnostic utility to determine the problem. 36
