The bi-color System Status LED will operate as follows:
Color State Criticality Description
Off N/A Not ready 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 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 (2).
 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
 Chassis Intrusion events, including lost LAN connection
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)
7.2.1 System Status LED – BMC Initialization
When the AC power is first applied to the system and 5V-STBY is present, the BMC controller
on the server board requires 15-20 seconds to initialize.
During this time, the system status LED
will blink, alternating between amber and green, and the power button functionality of the control
panel 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.
