 Unable to use all of the installed memory (more than one
DIMM installed).
 Correctable errors over a threshold of ten and migrating
to a spare DIMM (memory sparing). This indicates that
the user no longer has spare DIMMs indicating 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.
 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.
 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).
8.1.3 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.
