5.3.5.4.2Fault / Status LED

The following table shows mapping of sensors/faults to the LED state.

		Table 50: Fault / Status LED
Color	Condition	When
Green	Solid	System ready
	Blink	System ready, but degraded: CPU disabled
Amber	Solid	Critical failure: critical fan, voltage, or temperature state
	Blink	Non-critical failure: non-critical fan, voltage, or temperature state
Off	Solid	System not ready: POST error / NMI event / CPU or terminator missing

Critical Condition - Any critical or non-recoverable threshold crossing associated with the following events:

•Temperature, voltage, or fan critical threshold crossing

•Critical Event Logging errors, including System Memory Uncorrectable ECC errors and FSB Bus errors,.

Non-Critical Condition

•Temperature, voltage, or fan non-critical threshold crossing

•Chassis intrusion

Degraded Condition

•One or more processors are disabled by Fault Resilient Boot (FRB)

5.3.5.4.3Chassis ID LED

The Chassis ID LED provides a visual indication of a system being serviced. The state of the Chassis ID LED is toggled by the chassis ID button or it can be controlled by the Chassis Identify command.

		Table 51: Chassis ID LED
Color	Condition	When
Blue	Off	Ok
	Blink	Identify button pressed or Chassis Identify command executed

5.3.5.5Control Panel Inputs

The mBMC monitors the control panel switches and other chassis signals. The control panel input buttons are momentary contact switches, which are de-bounced by the mBMC processor firmware. The de-bounce time is 25 ms.
