The Chassis Identify Push-button works using a “push-on/push-off” operation. Each
press of the push-button toggles the LED signal state between on and off. If the
pushbutton is used to turn the LED on, it will stay on indefinitely, until either the button is
pressed again or a
Chassis Identify
or
Chassis Identify LED
command causes the LED
to turn off.

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 (e.g., 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). 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, 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.
