When the LEDs described in this table flash simultaneously, a power fault has occurred. For more information, see
Front panel LED power fault codes
on page 10.
If the health LED indicates a degraded or critical state, review the system IML or use iLO to review the system health
status.
Facility power is not present, power cord is not attached, no power supplies are installed, power supply failure has
occurred, or the front I/O cable is disconnected.
Server UID LED
The UID LED is used to locate a particular server when it is deployed in a dense chassis with other
equipment. Activating the UID LED helps an onsite technician to quickly identify a server for maintenance
tasks.
UID button functionality
The UID button can be used to display the Server Health Summary when the server will not power on.
