RJ-45 10BASE-T/100BASE-TX Port Status LED - Left (Link/Activity) (Continued)

Not lit

Ethernet link is down.

Alink-down detection condition exists due to any of the following fault conditions:

•10BASE-T/100BASE-TX fault on local module (Optic Fault LED is green or blinking red and 100BASE-FX Status LED is red)

or 10BASE-T/100BASE-TX fault

on remote module (Optic Fault LED is red and 100BASE-FX Status LED is not lit on local module):

–Disconnected or defective Category 5e (or higher) cable

–Cable is not the proper type.

–Cable is not the proper length.

–Defective 10BASE-T/ 100BASE-TX port

–Problem with external equipment connected to the 10BASE-T/ 100BASE-TX port

–Duplex mode setting (half- duplex or full-duplex) does not match the duplex mode setting of the remote module.

•100BASE-FX port on the module does not transmit or receive optical signal (Optic Fault LED is red and 100BASE-FX Status LED is not lit).

Do any of the following to restore the link:

•Check the cable that connects to the 10BASE-T/100BASE-TX port on the module:

–If the cable is disconnected from the module or from the 10BASE-T/100BASE-TX compati- ble device, connect the cable.

–If the cable is defective, replace the cable. Use Category 5e or higher cable.

–Ensure that the cable is the proper length. Cable length must not exceed 128 feet (100 meters).

–Replace the module if the 10BASE-T/100BASE-TX port is defective.

•Check the external equipment that connects to the 10BASE-T/ 100BASE-TX port on the module. Ensure that the equipment is powered on.

•Set the duplex mode setting on modules to match one another (auto- negotiation or forced half-duplex or full-duplex). Refer to the Setting 10BASE-T/100BASE-TX Port Modes of Operation section in this manual for information.

•Refer to the Optic Fault LED and 100BASE-FX Status LED sections in this table to troubleshoot 100BASE-FX fault conditions.
