TROUBLESHOOTING

Communication Mode

The communication mode of each port (half or full duplex and 10 Mbps or 100 Mbps) must be identical to the mode of the attached device. Verify that each port is set to the same communication modes used by the attached device. Each 100BASE-FX port must be configured for half- or full-duplex operation. For each 10BASE-T/100BASE-TX port, the communication mode is configured automatically via Auto- Negotiation. However, if the attached device does not support Auto-Negotiation, then you must configure the port manually.

(See Chapter 4, “Configuration and Management”, for port configuration instructions.)

Cabling

Verify that the cabling type is correct. Be sure all cable connectors are securely seated in the required ports. Also check to be sure you are using the proper cable type: straight- through or crossover. Use Category 5 twisted-pair cable for 100BASE-TX connections and Category 3, 4 or 5 cable for 10BASE-T connections. Use 62.5/125 micron core multimode fiber cable for 100BASE-FX connections.

Make sure all devices are connected to the network. Equipment may have been disconnected unintentionally.

Network Cards

Make sure the network interface hardware and software drivers for the attached devices are functioning properly. Check the network cards and associated drivers used in any attached workstation or server.

Physical Configuration

If problems occur after altering the network configuration, restore the original connections, and try to track the problems
