Table 70. System Status Led - Intel BB5520UR Technical Product Specification

Intel® Server Boards S5520HC, S5500HCV, and S5520HCT TPS
•
By issuing the appropriate hex IPMI "Chassis Identify" value, the ID LED will either blink
blue for 15 seconds and turn off or will blink indefinitely until the appropriate hex IPMI
Chassis Identify value is issue to turn it off.
The bi-color (green/amber) System Status LED operates as follows:
Color State
Green Solid on
Green Blink
Amber Blink
Amber Solid on
Off N/A
* 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.

Criticality
System OK
Degraded
Non-critical
Critical, non-
recoverable
Not ready
Intel order number E39529-013
System booted and ready.
System degraded
Non-critical temperature threshold asserted
–
Non-critical voltage threshold asserted
–
Non-critical fan threshold asserted
–
Fan redundancy lost, sufficient system cooling
–
maintained. This does not apply to non-redundant
systems.
Power supply predictive failure
–
– Power supply redundancy lost. This does not apply to
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
Critical voltage threshold asserted
–
– VRD hot asserted
SMI Timeout asserted
–
Fatal alarm – system has failed or shut down
– CPU Missing
Thermal Trip asserted
–
– Non-recoverable temperature threshold asserted
Non-recoverable voltage threshold asserted
–
Power fault/Power Control Failure
–
Fan redundancy lost, insufficient system cooling. This
–
does not apply to non-redundant systems.
Power supply redundancy lost insufficient system 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,
–
non-critical, critical, or non-recoverable conditions exist.
