Figure 81. Location of Front-Panel System Status LED
The front-panel system status LED has the states indicated in Table 10.
Critical Condition
A critical condition or non-recoverable threshold crossing is associated with the following events:
• Temperature, voltage, or fan critical threshold crossing.
• Power subsystem failure. The Baseboard
1
Management Controller (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 deasserted the signal to turn off power to the system).
• The system is unable to power up due to incorrectly installed processor(s), or processor incompatibility.
• A satellite controller such as the HSC, or another IMPI-capable device, such as an add-in server management
PCI card, sends a critical or non-recoverable state, via 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.
