Off System power is off, and the BIOS has not initialized the chipset.
On System power is on, but the BIOS has not yet initialized the chipset.
Off Mechanical is off, and the operating system has not saved any context
to the hard disk.
Off Mechanical is off. The operating system has saved context to the hard
disk.
Slow blink 1 DC power is still on. The operating system has saved context and
gone into a level of low-power state.
Steady on System and the operating system are up and running.

Criticality
Not ready AC power off
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.
Ok System booted and ready
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
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
Critical, non- Fatal alarm – system has failed or shutdown
DIMM failure when there is one DIMM present, no good
recoverable
memory present
