Color State System Status Description
Amber Solid on Fatal
Fatal alarm – system has failed or shut down:
BIOS Detected
1. DIMM failure when there is one DIMM present and
no good memory is present.
1
2. Run-time memory uncorrectable error in non-
redundant mode.
1
3. CPU configuration error (for instance, processor
stepping mismatch).
Integrated BMC Detected
1. CPU IERR signal asserted.
2. CPU 1 is missing.
3. CPU THERMTRIP.
4. No power good – power fault.
5. Power Unit Redundancy sensor – Insufficient
resources offset (indicates not enough power
supplies are present).
Off N/A Not ready AC power off
Notes:
1. The BIOS detects these conditions and sends a Set Fault Indication command to the
Integrated BMC to provide the contribution to the system status LED.
2. Support for an upper, non-critical threshold limit is not provided in default SDR
configuration. However if a user does enable this threshold in the SDR, then the system
status LED should behave as described.
