Component identification 10
• LFF LEDs and button
Item Description Status
1
Health LED* Solid green = Normal
Flashing green (1 Hz/cycle per sec) = iLO is rebooting
Flashing amber = System degraded
Flashing red (1 Hz/cycle per sec) = System critical**
2
Power On/Standby button
and system power LED*
Solid green = System on
Flashing green (1 Hz/cycle per sec) = Performing power on sequence
Solid amber = System in standby
Off = No power present†
3
NIC status LED* Solid green = Link to network
Flashing green (1 Hz/cycle per sec) = Network active
Off = No network activity
4
UID button/LED* Solid blue = Activated
Flashing blue:
1 Hz/cycle per sec = Remote management or firmware upgrade
in progress
4 Hz/cycle per sec = iLO manual reboot sequence initiated
8 Hz/cycle per sec = iLO manual reboot sequence in progress
Off = Deactivated
*When all four LEDs described in this table flash simultaneously, a power fault has occurred. For more information, see
"Power fault LEDs (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 power button cable is disconnected.
