Component identification 8
Item Description Status
1
Flashing green (1 flash per sec) = iLO is rebooting
Flashing amber = System degraded
2
Flashing red (1 flash per sec) = System critical
2
2
Solid green = Link to network
Flashing green (1 flash per second) = Network active
Off = No network activity
3
health/thermal LED
Solid green = Drives supported by the SAS expander are functional.
3
Solid amber = Failure or predictive failure of one or more drives supported
by the SAS expander.
3
Flashing amber (1 flash per sec) = The temperature sensor in one or more
front drives is about to reach the thermal threshold. Immediately slide the
front drive cages back into the chassis and keep them there until the LED
turns green.
4
Off = No power present
5
4
button and system
power LED
1
Flashing green (1 flash per second) = Performing power on sequence
Solid amber = System in standby
Off = No power present
5
5
Flashing blue:
1 flash per second = Remote management or firmware upgrade in
progress
4 flashes per second = iLO manual reboot sequence initiated
8 flashes per second = iLO manual reboot sequence in progress
Off = Deactivated
1
When these four LEDs flash simultaneously, a power fault has occurred. For more information, see "Power fault
LEDs (on page 8)."
2
If the health LED indicates a degraded or critical state, review the system IML or use iLO to review the system health
status.
3
This LED behavior applies to all front drives, as well as to the rear drives connected to the front drive cage 2
backplane.
4
This LED behavior depends on the iLO 08-HD Max sensor reading. For more information, see "Front drive thermal
LED (on page 9)."
5
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.
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.
