Cf Card Failure; Poe System Failure - HP 7500 Series Installation Manual

NOTE:
A combo interface comprises an SFP port and an RJ-45 Ethernet port. Only one of them can be
•
activated at a time.
If a port is brought down by the shutdown command, use the undo shutdown command to bring
•
up the port.
• After a port fails, if the switch has an idle port of the same type, you can plug the cable into the idle
port..
7. Verify that the speed and duplex settings of the ports of a link are the same. Make sure two ports
can work together.

CF card failure

The MPU provides a CFS LED. When the CF card operates correctly, the CFS LED is on.
If the CFS LED is off, the CFD card fails. To troubleshoot the CF card:
1. Verify that the MPU is operating correctly. For more information, see
2. If the CF card fails because you execute the umount command, you can execute the <Sysname>
mount cfa0: command in user view to re-mount the CF card.
3. Verify that the CF card is fully seated.
4. If you have a backup CF card, replace the current CF card with it to examine whether the current
CF card fails. For more information, see
CFS LED is on, you can be sure that the previous CF card fails.

PoE system failure

If the switch cannot supply power for a PD attached to the switch, troubleshoot the PoE system, as follows:
1. Make sure you have set up the PoE system for the switch as follows: use the PoE-capable switch
and LPUs, use the PoE-capable power supply system, and configure the PoE dual-in-line memory
(DIMM) modules for LPUs except LSQ3GV48SC0 and LSQ1GV48SD0. For more information, see
"Installing
2. Make sure the PoE system can provide enough power for all attached PDs. For information about
the maximum PoE power consumption, see
specifications."
3. Verify that the cable that connects the switch to the PD is a straight-through cable.
4. Make sure PoE-related configurations are correct. For how to configure PoE, see the related
configuration guide.
