System Identification
Off Off No Identification.
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 “S5300SF”.
7.2.1 Power/Sleep LED
Table 40. SSI Power LED Operation
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.
S4 ACPI Off Mechanical is off. The operating system has saved context to the hard
disk.
S3-S1 ACPI Slow blink 1 DC power is still on. The operating system has saved context and
gone into a level of low-power state.
S0 ACPI Steady on System and the operating system are up and running.
Note:
Blink rate is ~ 1Hz with at 50% duty cycle.

Unable to use all of the installed memory (more than one
DIMM installed).
Correctable errors over a threshold of 10 and migrating to a
spare DIMM (memory sparing). This indicates that the user
no longer has spared DIMMs indicating a redundancy lost
condition. Corresponding DIMM LED should light up.
