System Status LED

The bi-color (green/amber) System Status LED operates as follows:
Color State Criticality
Green Solid on System OK
Green Blink Degraded
Amber Blink Non-critical
Critical, non-
Amber Solid on
recoverable
Off N/A Not ready
* When the server is powered down (transitions to the DC-off state or S5), the BMC is still on standby power and
retains the sensor and front panel status LED state established before the power-down event. If the system status is
normal when the system is powered down (the LED is in a solid green state), the system status LED is off.
10.4.3

POST Code Diagnostic LEDs

During the system boot process, the BIOS execute a number of platform configuration
processes, each of which is assigned a specific hex POST code number. As each configuration
routine is started, the BIOS display the given POST code to the POST code diagnostic LED's on
the back edge of the server boards. To assist in troubleshooting a system hang during the
POST process, you can use the diagnostic LEDs to identify the last POST process executed.

Description
System booted and ready.
System degraded
Non-critical temperature threshold asserted

Non-critical voltage threshold asserted

Non-critical fan threshold asserted
o
Fan redundancy lost, sufficient system cooling
o
maintained. This does not apply to non-redundant
systems.
Power supply predictive failure
o
Power supply redundancy lost. This does not apply to
o
non-redundant systems.
Correctable errors over a threshold of 10 and migrating to

a mirrored DIMM (memory mirroring). This indicates the
user no longer has spare DIMMs indicating a redundancy
lost condition. The corresponding DIMM LED should light
up.
Non-fatal alarm – system is likely to fail:
Critical temperature threshold asserted

CATERR asserted
o
Critical voltage threshold asserted
o
VRD hot asserted
o
SMI Timeout asserted
o
Fatal alarm – system has failed or shut down
CPU Missing

Thermal Trip asserted

Non-recoverable temperature threshold asserted
o
Non-recoverable voltage threshold asserted
o
Power fault/Power Control Failure
o
Fan redundancy lost, insufficient system cooling. This
o
does not apply to non-redundant systems.
Power supply redundancy lost insufficient system
o
power. This does not apply to non-redundant systems.
Note: This state also occurs when AC power is first applied to
the system. This indicates the BMC is booting.
AC power off, if no degraded, non-critical, critical, or non-

recoverable conditions exist.
System is powered down or S5 states, if no degraded,
o
non-critical, critical, or non-recoverable conditions
exist.
