Description
Green Solid on Ok
System ready
Green
~1 Hz blink
Degraded
System degraded:
1. Unable to use all of the installed memory (more than one DIMM
installed).
1
BIOS detected
2. In a mirrored configuration, when memory mirroring takes place
and system loses memory redundancy. This is not covered by
(2).
1
3. PCI Express* correctable link errors.
Integrated
1. Redundancy loss such as power supply or fan.
Applies only if
the associated platform subsystem has redundancy capabilities.
BMC detected
2. CPU disabled – if there are two CPUs and one CPU is disabled.
3. Fan alarm – Fan failure. Number of operational fans should be
more than minimum number needed to cool the system.
4. Non-critical threshold crossed – Temperature, voltage, power
nozzle, power gauge, and PROCHOT
2
(Therm Ctrl) sensors.
5. Battery failure.
6. Predictive failure when the system has redundant power
supplies.
Amber
~1 Hz blink
Non-Fatal
Non-fatal alarm – system is likely to fail:
1. In non-mirroring mode, if the threshold of ten correctable errors
is crossed within the window
1
.
BIOS Detected
2. PCI Express* uncorrectable link errors.
3. Critical threshold crossed – Voltage, temperature, power nozzle,
power gauge, and PROCHOT (therm Ctrl) sensors.
Integrated BMC Detected
4. VRD Hot asserted.
5. Minimum number of fans to cool the system are not present or
have failed.
