Solution
To resolve the issue:
1.
Verify that the SEM is operating correctly. For more information, see "
."
2.
Verify that the system software version is compatible with interface switch module. If not
compatible, upgrade the software to a compatible version.
3.
Calculate the total power consumption, and make sure your power supplies can provide
enough power. For more information, see "Appendix B Technical specifications."
4.
Remove and reinstall the interface switch module to make sure it is installed securely. For the
interface switch module installation procedure, see "Installing the gateway."
5.
If the gateway has empty card slots, insert the module into an empty slot and identify whether
the module can operate correctly. If the module operates correctly, the original interface switch
module slot is damaged.
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 SEM, interface module, or service module where the interface resides operates
correctly. For more information, see "
Switching fabric module failure
."
2.
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 "Appendix D Cables."
3.
If the interface uses a transceiver module, make sure the interface type is compatible with the
transceiver. For more information, see "Appendix A FRUs and compatibility matrixes."
4.
If the interface uses a transceiver, make sure the current transceiver operates correctly by
replacing a normal transceiver.
5.
Verify that the speed and duplex settings of the interfaces of a link are the same. Make sure two
interfaces can work together.
6.
If the issue persists, contact H3C Support.
