System booted and ready

Degraded
System degraded
Including, but not limited to:
 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 spare DIMMs specifying a redundancy lost
condition. The corresponding DIMM LED should light up.
 In a mirrored configuration, when memory mirroring takes
place and system loses memory redundancy. This is not
covered by the second bullet above.
 Redundancy loss such as power supply or fan. This does not
apply to non-redundant subsystems.
 PCI Express* 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 the 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.
Including, but not limited to:
 Critical voltage threshold crossed.
 VRD hot asserted.
 Minimum number of fans to cool the system are not present or
have 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 shut down
Including, but not limited to:
 DIMM failure when there is one DIMM present and no good
memory is present.
 Run-time memory uncorrectable error in non-redundant mode.
 IERR signal asserted.
 Processor 1 missing.
 Temperature (e.g. CPU ThermTrip, memory TempHi, critical
threshold crossed).
 No power good – power fault.
 Processor configuration error (e.g. processor stepping
mismatch).
7.2.3 Drive Activity LED
The drive activity LED on the front panel indicates drive activity from the on-board hard disk
controllers. The Intel
®
Server Board S5520UR also provides a header giving access to this LED
for add-in controllers.
