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 Intel
®
Server Board S5520UR.
