Intel S5000XAL manual System Status LED BMC Initialization, Color State Criticality Description

Intel® Server Board S5000PAL / S5000XAL TPS Light Guided Diagnostics

The bi-color System Status LED will operate as follows:

Color	State	Criticality		Description
Off	N/A	Not ready	AC power off
Green /	Alternating	Not ready	Pre DC Power On – 15-20 second BMC Initialization when AC is
Amber	Blink		applied to the server. Control Panel buttons are disabled until BMC
			initialization is complete.
Green	Solid on	System OK	System booted and ready.
Green	Blink	Degraded	System degraded
			• Unable to use all of the installed memory (more than one
				DIMM installed).
			• Correctable errors over a threshold of 10 and migrating to a
				spare DIMM (memory sparing). This indicates that the user
				no longer has spared DIMMs indicating a redundancy lost
				condition. Corresponding DIMM LED should light up.
			• In mirrored configuration, when memory mirroring takes
				place and system loses memory redundancy. This is not
				covered by (2).
			• Redundancy loss such as power-supply or fan. This does
				not apply to non-redundant sub-systems.
			• PCI-e link errors
			• CPU failure / disabled – if there are two processors and one
				of them fails
			• Fan alarm – Fan failure. Number of operational fans should
				be more than minimum number needed to cool the system
			• Non-critical threshold crossed – Temperature and voltage
Amber	Blink	Non-critical	Non-fatal alarm – system is likely to fail
			• Critical voltage threshold crossed
			•	VRD hot asserted
			• Minimum number of fans to cool the system not present or
				failed
			• In non-sparing and non-mirroring mode if the threshold of
				ten correctable errors is crossed within the window
Amber	Solid on	Critical, non-	Fatal alarm – system has failed or shutdown
		recoverable	• DIMM failure when there is one DIMM present, no good
				memory present
			• Run-time memory uncorrectable error in non-redundant
				mode
			•	IERR signal asserted
			•	Processor 1 missing
			• Temperature (CPU ThermTrip, memory TempHi, critical
				threshold crossed)
			• No power good – power fault
			• Processor configuration error (for instance, processor
				stepping mismatch)

7.2.1System Status LED – BMC Initialization

When the AC power is first applied to the system and 5V-STBY is present, the BMC controller on the server board requires 15-20 seconds to initialize. During this time, the system status LED will blink, alternating between amber and green, and the power button functionality of the control panel is disabled preventing the server from powering up. Once BMC initialization has completed, the status LED will stop blinking and the power button functionality is restored and can be used to turn on the server.
