Check LED status

Checking the LED status

The device provides various LEDs to indicate the operating status of different objects. If a LED
indicates an abnormal state, record the failure information immediately and see the installation guide
for the router for how to troubleshoot and resolve the issue. If the issue persists, contact H3C
Support.
See the tables in this section to understand normal LED activity. The number and status of LEDs of
the same type for one type of card depend on the card model. For example, an MPU might provide
two fan tray status LEDs (OK and FAIL) or one fan tray status LED (OK/FAIL), depending on the
MPU model.
For more information about the descriptions of the LEDs, see the installation guide for the router.
