3.
Check the cable for any breakage. Use the cable to connect two interfaces of the same type that
are working properly. If the LEDs of the two interfaces are on, the cable is normal; otherwise, the
cable fails. Use a compliant cable to connect the interface.
4.
If the interface uses a transceiver module, make sure the interface type is compatible with the
transceiver module and that the transceiver module is compatible with the cable. For more
information, see "Appendix C Transceiver modules."
5.
If the interface uses a transceiver module, replace the module with a normal transceiver module. If
the problem persists after the replacement, you can rule out the transceiver module failure.
6.
If the LED is for a copper or fiber combo port, make sure the port has been activated. If not, use the
combo enable { copper | fiber } command to activate it. If the LED is still off, the interface or the link
has failed.
A combo interface has one fiber port and one copper port. These two ports (called "combo ports")
share one transmission channel and cannot work simultaneously. When you activate one port, the
other port automatically shuts down.
7.
Use the display interface command to check the status of the interface. If the interface is not UP, use
the undo shutdown command to bring up the interface.
8.
Make sure the interface is using the same speed and duplex settings as the remote interface.
9.
If the failure persists, contact the local agents or technical support engineers.
NOTE:
After an interface fails, you can unplug its cable and connect the cable to an idle interface of the same type
to continue services.
Technical support
