Power supply LEDs

The various states of the power supply light-emitting diodes (LEDs) can be used to identify or verify a power supply that you are servicing.

The power supply has three LEDs that indicate the power supply status:

van ac power LED (green, at the right of the 3 LEDs)

va dc power LED (green, in the middle of the 3 LEDs)

van error and identify function LED (amber, at the left of the 3 LEDs)

To locate the power supply LEDs, look on the top or at the back of an exposed power supply. You must remove covers or panels to expose the power supply. Follow the instructions to remove covers or panels for the power supply you are working with, and then return here.

To activate the identify function, see “Identifying a part” on page 36.

Descriptions for the states of the power supply LEDs follow:

vIf both the ac power and dc power (green) LEDs are on solid (not flashing) and the error and identify function (amber) LED is off, the power supply is operating correctly.

vIf the ac power LED is on, the dc power LED is flashing, and the error and identify function (amber) LED is off, then the system is turned off, but the power supply is still connected to the power source.

vIf the error and identify function (amber) LED is flashing, the power supply identify function has been selected.
