Troubleshooting

❑Make sure that the twisted-pair cable does not exceed 100 meters (328 feet) and that you are using a Category 3 or better cable for 10Base-T operation or a Category 5 or better cable for 100Base-TX operation.

For information about maximum operating distances, see Table 1 on page 3.

If the LNK/ACT LED for the fiber optic port is OFF, do the following:

❑Verify that the end-node connected to the port is ON and is operating properly.

❑Check that the fiber optic cable is securely connected to the fiber optic port on the switch and on the end-node.

❑Check that the end-node connected to the port is operating at 100 Mbps.

❑Check that the end-nodes connected to the switch are operating at the same duplex mode.

❑Make sure that the cable connected to the switch’s receiver port (RX) is connected to the end-node’s transmitter port (TX) and that the switch’s transmitter port (TX) is connected to the end-node’s receiver port (RX).

❑Test the attenuation on the fiber cable to ensure that it does not exceed acceptable values.

❑Verify that you are using the appropriate type of fiber optic cables and that you have not exceeded the maximum operating distances. For the maximum operating distances, refer to Table 1 on page 3 and for the cable types, refer to Table 3 on page 12, Table 4 on page 12, or Table 5 on page 14.

❑Check that the operating specifications of the fiber optic port on the end-node are compatible with the operating specifications of the fiber optic port on the switch. For the fiber optic port specifications, refer to refer to Table 1 on page 3 and for the cable types, refer to Table 3 on page 12, Table 4 on page 12, or Table 5 on page 14.
