Front panel LED power fault codes
When a power fault occurs, the following front panel LEDs flash simultaneously:
- System power LED
- Health LED
- NIC LED
- UID LED
For more information about the LED locations on your server, see the server user guide in the Hewlett Packard Enterprise Information Library.
The number of flashes in each sequence corresponds to the subsystem impacted by the power fault. The following table provides a list of power fault codes, and the subsystems that are affected. Not all power faults are used by all servers.
