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
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.
