Chapter 1 Power and Relay Connector You connect the DC power and alarm signals to the switch through two front panel connectors. One connector provides primary DC power (supply A) and the major alarm signal, and a second connector (supply B) provides secondary power and the minor alarm signal. The two connectors are physically identical and are in the upper left side of the front panel, as shown in the figure below. The switch accessory pack includes the mating power and relay connectors.
Chapter 1 See the Stratix 8000 Ethernet Managed Switches Software User Manual, publication 1783-UM003A, for more information on alarm configuration.. For more information about the power and relay connector, see Chapter 4, Cable and Connectors. Console Port For configuring, monitoring, and managing the switch, you can connect a switch to a computer through the console port and the supplied RJ45-to-DB-9 adapter cable.
Chapter 1 10/100 Ports You can set the 10/100 ports to operate at 10 or 100 Mb/s in full-duplex or half-duplex mode. You can also set these ports for speed and duplex autonegotiation in compliance with IEEE 802.3-2002. (The default setting is autonegotiate.) When set for autonegotiation, the port senses the speed and duplex settings of the attached device.
Chapter 1 Cabling 100BASE-TX traffic requires Category 5 cable. 10BASE-T traffic can use Category 3 or Category 4 cables. When connecting the switch to workstations, servers, and routers, straight-through cables are normally used. However, the automatic medium-dependent interface crossover (auto-MDIX) feature of the switch is enabled by default and will automatically re-configure the ports to use either straight-through or crossover cable type.

Chapter 2 Verify Switch Operation Before installing the switch in its final location, you should power on the switch and verify that the switch passes the power-on self-test (POST). These sections describe the steps required to connect a personal computer or terminal to the switch console port, to power on the switch, and to observe POST results.
Chapter 2 Run a Power-on Self-test (POST) When the switch powers on, it automatically initiates a POST. The POST runs a series of tests that verify that the switch functions properly and assures that it is ready to install. To test the switch, follow these steps. 1. Apply power to the switch. 2. Verify POST Results, page 63. 3. Disconnect Power, page 64. Verify POST Results When you apply power the switch, it automatically begins a series of self tests (POST). During a POST, you see the following.
Chapter 2 Disconnect Power After successfully running POST, follow these steps. 1. Turn off power to the switch. 2. Disconnect the cables. 3. Decide where you want to install the switch. Install and Remove SFP Modules These sections describe how to install and remove Small Form-factor Pluggable (SFP) modules. SFP modules are inserted into SFP module slots on the front of the switch. These field-replaceable modules provide the uplink optical interfaces, send (TX) and receive (RX).
Chapter 2 To insert an SFP module into the SFP module slot, follow these steps: 1. Attach an electrostatic discharge (ESD) preventive wrist strap to your wrist and to a bare metal surface on the chassis. 2. Find the send (TX) and receive (RX) markings that identify the correct side of the SFP module. On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX). 3.
Chapter 2 4. Unlock and remove the SFP module, as shown the following figure. Bale Clasp Latch . 5. If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch. 6. Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot. 7.
Chapter 2 Connect to SFP Modules This section describes how to connect to a fiber-optic SFP port. To connect to an RJ45 Gigabit Ethernet port instead of a fiber-optic port, see the Connect to the Switch Ports section on page 58. Follow these steps to connect a fiber-optic cable to an SFP module: WARNING Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable.
Chapter 2 4. Observe the port status indicator. • The status indicator turns green when the switch and the target device have an established link. • The status indicator turns amber while the SFP module discovers the network topology and searches for loops. This process takes about 30 seconds, then the port status indicator turns green.
Chapter 3 Troubleshoot the Switch This chapter provides these topics for troubleshooting the switch. Topic Page Obtain Troubleshooting Information 69 Verify Switch POST Results 69 Verify Switch Status Indicators 70 Verify Switch Connections 70 Verify Switch Performance 73 Obtain Configuration Information 74 Obtain Troubleshooting Information The status indicators on the front panel provide troubleshooting information about the switch.
Chapter 3 View POST Results With a Terminal If you have a terminal connected to the console port, you can also view POST status and test results on the terminal. If the terminal displays garbled characters, you might need to reset the terminal-emulation software to 9600 bits per second. Refer to Verify POST Results on page 63 for more information about viewing results on a terminal.
Chapter 3 This situation is likely when the port has many packet errors or the port constantly loses and regains the link. You should: • Swap the copper or fiber-optic cable with a known, good cable. • Look for broken, bent, or missing pins on cable connectors. • Rule out any bad patch panel connections or media convertors between the source and destination. If possible, bypass the patch panel, or eliminate faulty media convertors (fiber-optic-to-copper).
Chapter 3 Link Status Verify that both sides have a network link. A single broken wire or one shut down port can cause one side to show a link, but not the other side. A Link status indicator does not guarantee that the cable is fully functional. The cable might have encountered physical stress that causes it to function at a marginal level. If the Link status indicator for the port is not lit, do the following. • Connect the cable from the switch to a known good device.
Chapter 3 Port and Interface Settings A cause of port connectivity failure can be a disabled port. Verify that the port or interface is not disabled or powered down for some reason. If a port or interface is manually shut down on one side of the link or the other side, the link does not come up until you re-enable the port. Use the CLI show interfaces privileged EXEC command to verify the port or interface error-disabled, disabled, or shutdown status on both sides of the connection.
Chapter 3 Autonegotiation and Network Interface Cards (NICs) Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch ports and interfaces are set to autonegotiate. It is common for devices like laptops or other devices to be set to autonegotiate as well, yet sometimes autonegotation issues occur. To troubleshoot autonegotiation problems, try manually setting both sides of the connection.
Chapter 4 Cable and Connectors This appendix describes the switch ports and the cables and adapters that you use to connect the switch to other devices. 10/100 and 10/100/1000 Ports The 10/100 and 10/100/1000 Ethernet ports on switches use standard RJ45 connectors and Ethernet pinouts with internal crossovers. The auto-MDIX feature is enabled by default. TIP The following figure shows the connector pinouts.
Chapter 4 Connect to 10BASE-T- and 100BASE-TX-Compatible Devices When connecting the ports to 10BASE-T- and 100BASE-TX-compatible devices, such as servers, workstations, and routers, you can use a two or four twisted-pair, straight-through cable wired for 10BASE-T and 100BASE-TX. To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side-by-side, with the tab at the back.
Chapter 4 Use a straight-through cable to connect two ports only when one port is designated with an X. Use a crossover cable to connect two ports when both ports are designated with an X or when both ports do not have an X. You can use Category 3, 4, or 5 cabling when connecting to 10BASE-T-compatible devices. You must use Category 5 cabling when connecting to 100BASE-TX-compatible devices.
Chapter 4 100BASE-FX Ports The 100BASE-FX ports use the following: • LC connectors, as shown in the following figure. • 50/125- or 62.5/125-micron multimode fiber-optic cables 58476 Fiber-optic SFP Module LC Connector ATTENTION SFP Module Ports The switch uses SFP modules for fiber-optic uplink ports.
