Interface Failure - HP FlexFabric 12900 series Installation Manual

4. Verify that the card is fully seated by removing the card and installing it again. For a switching
fabric module, you must verify that the ejector levers touch the panel tightly. For more information
about installing an LPU and a switching fabric module, see
5. If the switch has empty card slots, install the card into another slot. If the card can operate correctly,
the previous slot is faulty.
6. If the failure persists, contact HP Support.

Interface failure

The interfaces provided by MPUs and LPUs all have corresponding LEDs. When an interface connected
to the network operates correctly, the corresponding LED is on.
NOTE:
A management Ethernet port has two LEDs, LINK and ACT. When the LINK LED is steady on, the
management Ethernet port is operating correctly. Each interface of any other type has only one LED.
If the LED of an interface connected to the network is off, the interface or the connecting cable may fail.
To troubleshoot the interface:
1. Make sure the MPU or LPU where the interface resides operates correctly. For more information,
see "MPU
2. Examine the cable connection of the interface. For how to correctly connect the cable to an
Ethernet interface, see
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 normal. Otherwise, the
cable fails. 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
5. If the interface uses a transceiver, make sure the current transceiver operates correctly by replacing
a normal transceiver.
NOTE:
If an interface is brought down by the shutdown command, use the undo shutdown command to
•
bring up the interface.
After an interface fails, if the switch has an idle interface of the same type, you can plug the cable
•
into the idle interface.
6. Verify that the speed and duplex settings of the interfaces of a link are the same. Make sure two
interfaces can work together.
7. If the failure persists, contact HP Support.
