When all four LEDs described in this table flash simultaneously, a power fault has occurred. For more information, see

Power fault LEDs.

UID button functionality

The UID button can be used to display the Server Health Summary when the server will not power on. For more
information, see the latest HPE iLO 5 User Guide on the Hewlett Packard Enterprise website.
Power fault LEDs
The following table provides a list of power fault LEDs, and the subsystems that are affected. Not all power faults are used
by all servers.
Subsystem
System board
Processor
Memory
Riser board PCIe slots
Health LED
NIC status LED
Power On/Standby button
and system power LED
Solid green = Normal
Flashing green (1 flash per second) = iLO is rebooting
Flashing amber = System degraded
Flashing red (1 flash per second) = System critical
If the health LED indicates a degraded or critical state, review the
system IML ("Integrated Management Log" on page 129) or use iLO
("HPE iLO" on page 127) to review the system health status.
Solid green = Link to network
Flashing green (1 flash per second) = Network active
Off = No network activity
Solid green = System on
Flashing green (1 flash per second) = Performing power on sequence
Solid amber = System in standby
Off = No power present
If the system power LED is off, verify the following conditions:
• The facility power is present.
• The power supply is installed and is working correctly.
• The power cord is attached and is connected to a power source.
• The front I/O cable is connected.
