System Status LED

Critical Condition

Any critical or non‐recoverable threshold crossing associated with the following events:
• Temperature, voltage, or fan critical threshold crossing.
• Power subsystem failure. The BMC asserts this failure whenever it detects a power control
fault (for example, the BMC detects that the system power is remaining on even though the
BMC has instructed the signal to turn off power to the system). A hot‐swap backplane would
use the Set Fault Indication command to indicate when one or more of the drive fault status
LEDs are asserted on the hot‐swap backplane.
• The system is unable to power up due to incorrectly installed processor(s), or processor
incompatibility.
• Satellite controller sends a critical or non‐recoverable state, using the Set Fault Indication
command to the BMC.
• "Critical Event Logging" errors, including: System Memory Uncorrectable ECC error and
Fatal/Uncorrectable Bus errors, such as PCI SERR and PERR.

Non-Critical Condition

• Temperature, voltage, or fan non‐critical threshold crossing.
• Chassis intrusion.
• Satellite controller sends a non‐critical state, via the Set Fault Indication command, to the BMC.
