1 Health LED

Solid green = Normal

Flashing green (1 flash per sec) = iLO is rebooting

Flashing amber = System degraded[2]

Flashing red (1 flash per sec) = System critical2

2 NIC status LED1

Solid green = Link to network

Flashing green (1 flash per second) = Network active

Off = No network activity

3 Front drive 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 Power On/Standby button and system power LED1

Solid green = System on

Flashing green (1 flash per second) = Performing power on sequence

[1] When these four LEDs flash simultaneously, a power fault has occurred. For more information, see Power fault LEDs.
[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.
[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.
