Identification
Blue On Identify active via command or button.
Off Off No Identification.
Notes:
1. Blink rate is ~1 Hz at 50% duty cycle.
2. The amber status takes precedence over the green status. When the amber LED is on or blinking, the
green LED is off.
3. Off when the system is powered off (S4/S5) or in a sleep state (S1).
4. The power LED sleep indication is maintained on standby by the chipset. If the system is powered down
without going through the BIOS, the LED state that is in effect at the time of power off is restored when the
system is powered on until the BIOS clears it. If the system is not powered down normally, it is possible that
the power LED is blinking while the system status LED is off. This is due to a failure or configuration change
that prevents the BIOS from running.
The current limiting resistors for the power LED, the system fault LED, and the NIC LEDs are
located on the server board.

State Power Mode LED Description
Power-off Non-ACPI Off System power is off, and the BIOS has not initialized the chipset.
Power-on Non-ACPI On System power is on, but the BIOS has not yet initialized the chipset.
S5 ACPI Off Mechanical is off, and the operating system has not saved any
context to the hard disk.
