Notes:
1. Blink rate is ~1 Hz with 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. Also 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 BIOS, the LED state in effect at the time of power off will be 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 will be blinking at the same time that the system status LED is off 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 Intel
®
Server Board S5000PAL.
