Failure of the OAP card in an expansion interface card slot
You can use the LEDs on the OAP card to identify its operating status. For more information about the
LEDs, see the user manual that comes with the card. If your switch has a status LED for the expansion
interface card slot, you can also use the LED to identify the operating status of the card.
If the OAP card is not correctly operating, verify the following items:
• The OAP card is compatible with the switch and can be installed in an expansion interface card
slot.
• The OAP card is correctly installed and well seated in the slot.
NOTE:
If the problem persists, contact your local H3C sales agent or service engineer for help.

Fan tray failure
You can look at the system status LED and the seven-segment LED of an S5820X switch to identify a fan
failure. If both LEDs behave as described in
Table 29 , a fan failure has occurred.

The LED displays F for fan failure.
To replace a failed fan tray, follow the procedure described in “ Installing/Removing a fan tray .”
CAUTION:

the failed fan tray within 2 minutes for an S5820X-28C or S5820X-28S switch.
