Power Indicator

Description

 

Pattern

 

 

 

 

A

Green

A valid power source is connected to the PSU and the PSU is

 

 

operational.

B

Flashing green

When the firmware of the PSU is being updated, the PSU handle

 

 

flashes green.

 

 

CAUTION: Do not disconnect the power cord or unplug the

 

 

PSU when updating firmware. If firmware update is

 

 

interrupted, the PSUs will not function. You must roll back the

 

 

PSU firmware by using Life cycle controller. See Dell Lifecycle

 

 

Controller User’s Guide at dell.com/esmmanuals.

C

Flashing green

When hot-adding a PSU, the PSU handle flashes green five times at

 

and turns off

4 Hz rate and turns off. This indicates that there is a PSU mismatch

 

 

with respect to efficiency, feature set, health status, and supported

 

 

voltage. Replace the PSU with a PSU that matches the capacity of

 

 

the PSU.

 

 

CAUTION: For AC power supplies, use only PSUs with the

 

 

Extended Power Performance (EPP) label on the back. Mixing

 

 

PSUs from previous generations of PowerEdge servers can

 

 

result in a PSU mismatch condition or failure to power on.

D

Flashing amber

Indicates a problem with the PSU.
