When the AC power is first applied to the system and 5-volt standby is present, the BMC on the
server board requires 15-20 seconds to initialize. During this time, the system status LED blinks
amber and green, and the power button functionality is disabled, preventing the server from
powering up. Once BMC initialization has completed, the status LED will stop blinking and the
power button functionality is restored and can be used to turn on the server.
The bi-color 5V Standby System Status LED operates as follows:

AC power off
Green/Amber Alternating
Blink
Not ready
Pre-DC power on – 15-20 second BMC initialization when AC is
applied to the server. Control Panel buttons are disabled until the
BMC initialization is complete.
Green
Solid on
System OK
System booted and ready.
Green
Blink
Degraded
System degraded
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.
In mirrored configuration, when memory mirroring takes
place and system loses memory redundancy. This is not
covered by the bullet above.
Redundancy loss such as power-supply or fan. This does
not apply to non-redundant sub-systems.
PCI-e link errors
CPU failure/disabled – if there are two processors and one
of them fails
Fan alarm – Fan failure. Number of operational fans should
be more than minimum number needed to cool the system
Non-critical threshold crossed – Temperature and voltage
Amber
Blink
Non-critical
Non-fatal alarm – system is likely to fail
Critical voltage threshold crossed
VRD hot asserted
Minimum number of fans to cool the system not present or
failed
In non-sparing and non-mirroring mode if the threshold of
ten correctable errors is crossed within the window
Amber
Solid on
Critical, non-
recoverable
Fatal alarm – system has failed or shutdown
DIMM failure when there is one DIMM present, no good
memory present
Run-time memory uncorrectable error in non-redundant
mode
IERR signal asserted
Processor 1 missing
Temperature (CPU ThermTrip, memory TempHi, critical
threshold crossed)
No power good – power fault
Processor configuration error (for instance, processor
stepping mismatch)
