Interface Failure - HP FlexFabric 11908-V Installation Manual

3. Calculate the total power consumption, and make sure your power supplies can provide enough
power. For more information, see
4. Verify that the card is fully seated. You can unplug the card, plug it again, and press the ejector
levers inward until the ejector levers touch the panel tightly. For a switching fabric module, you
must verify that the ejector levers touch the panel tightly and the switching fabric module seats into
the backplane.
5. If the switch has empty card slots, plug the card into an empty card slot, and verify that the card
can operate correctly.
6. If the failure persists, contact HP Support for help.

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 interface has two LEDs, LINK and ACT. The LED in this section for such an
interface refers to the LINK LED. 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 is operating 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 with an RJ-45 connector or an optical interface, see
the network."
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 module, make sure the current transceiver works correctly by
replacing a normal transceiver.
NOTE:
If a port 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 for help.
