LED Summary

Power Supply LEDs

Table 5-15summarizes the power supply LEDs for both the AC and DC power supplies.

	Table 5-14	Power Supply LEDs

	LED	Color/State	Description

	Input OK	Off	No Input Voltage

		Amber	Input voltage out of range

		Green	Input voltage within acceptable operating range

	Output Fail	Off	Disabled/Forced Shut down/No input power

		Red	Power supply fault (internal failure such as over temperature)

		Green	Operational

	LED	Color/State	Description

	Input Power	Off	No input voltage
	(PWR)
	(PWR)	Amber	Input voltage out of range
		Amber	Input voltage out of range

		Green	Input voltage within acceptable operating range

	Status	Off	Disabled/power-down/no power
	(STAT)
	(STAT)	Red	Power supply fault (internal failure)
		Red	Power supply fault (internal failure)

		Green	Operational
