2.
Examine the cable connection of the interface. For information about how to correctly connect the
cable to an Ethernet interface with an RJ-45 connector or an optical interface, see "Connecting the
router to the network."
3.
Verify that the cable is not broken. Use the cable to connect two interfaces of the same type that
operate correctly. 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, verify that the interface type is compatible with the
transceiver module and that the transceiver module is compatible with the cable. For more
information, see "Appendix A Technical specifications."
5.
If the interface uses a transceiver module, make sure the current transceiver module is operating
correctly by replacing a normal transceiver module.
6.
If the interface is a combo interface (which contains a fiber port and a copper port), make sure the
interface used for connection is activated for the combo interface. Use the combo enable { copper
| fiber } command to activate the interface, and examine the LED status.
7.
Use the display interface command to verify that the interface is up. If the interface is not up, use
the undo shutdown command to bring it up.
8.
Verify that the speed and duplex settings of the interfaces of a link are the same. Make sure two
interfaces can work together.
9.
If the failure still exists, contact the local agents or technical support engineers.
NOTE:
When an interface fails, if the router has an idle interface of the same type, you can plug the cable into the
idle interface.
Technical support
If the failures still exist, contact the agents or technical support engineers. Before contacting the customer
service, prepare the following information to help the agents solve the problem as quickly as possible:
•
Arrival time of the router
•
Serial number of the chassis (located on a label on the rear panel)
•
Software version (which you can view by using the display version command)
•
Maintenance agreement or warranty card
•
Brief problem description
•
Brief explanation of the troubleshooting measures that have been taken
You can contact the customer service through the customer service hotline, the H3C website, or email.
