4.
Verify that the card is fully seated. You can remove the card, install it again, and press the
ejector levers inward until the ejector levers touch the panel tightly.
5.
If the gateway has empty card slots, plug the card into an empty card slot, and verify that the
card can operate correctly.
6.
If the issue persists, contact H3C Support.
Interface failure
Symptom
The LED of an interface connected to the network is off.
Solution
To resolve the issue:
1.
Verify that the MPU, interface module, or service module where the interface resides operates
correctly. For more information, see "
" or "
Interface module, service module, or
switching fabric module failure
2.
Examine the cable connection of the interface. For how to correctly connect the cable to an
Ethernet interface with an RJ-45 connector or an optical interface, see "Connecting network
cables."
3.
Verify that the cable is in good condition. 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 in good
condition. If they are not on, the cable has failed. Use a compliant cable to connect the interface.
For more information about the compliant cables, see "
."
4.
If the interface uses a transceiver module, make sure the interface type is compatible with the
transceiver and that the transceiver is compatible with the cable. For more information, see
"
Appendix B FRUs and compatibility matrixes
."
5.
If the interface uses a transceiver, make sure the current transceiver operates correctly by
replacing a normal transceiver.
6.
If the interface is a combo interface, make sure the port used for connection is activated. If the
port is not activated, use the
combo enable
{
copper
|
fiber
} command to activate the port,
and verify the LED.
A combo interface is a logical interface that contains one fiber port and one copper port. The
two ports share one interface view and cannot work simultaneously. When you enable either
port, the other port is automatically disabled. You can activate either port as needed. The
default operating port is the copper port.
7.
Verify that the speed and duplex settings of the interfaces of a link are the same. Make sure that
two interfaces can work together.
8.
If the issue persists, contact H3C Support.
NOTE:
•
If a port is brought down by the
shutdown
command, use the
undo shutdown
command to
bring up the interface.
•
A management Ethernet interface or XFP interface each has two LEDs, LINK and ACT. The LED
mentioned in this section for such an interface refers to the LINK LED. Each interface of any
other type has only one LED.
•
When an interface fails, if the gateway has an idle interface of the same type, you can install the
cable into the idle interface.
