Power indicator codes
Condition
Green
A valid power source is connected to the PSU and the PSU is operational.
Blinking amber
Indicates a problem with the PSU.
Not illuminated
Power is not connected to the PSU.
Blinking green
When the firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION:
Do not disconnect the power cord or unplug the PSU when updating firmware. If
firmware update is interrupted, the PSUs do not function.
Blinking green and turns off When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off. This
indicates a PSU mismatch with respect to efficiency, feature set, health status, or supported voltage.
CAUTION:
If two PSUs are installed, both the PSUs must have the same type of label; for
example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of
PowerEdge servers is not supported, even if the PSUs have the same power rating. This results
in a PSU mismatch condition or failure to turn the system on.
CAUTION:
When correcting a PSU mismatch, replace only the PSU with the blinking indicator.
Swapping the PSU to make a matched pair can result in an error condition and unexpected
system shutdown. To change from a high output configuration to a low output configuration or
vice versa, you must turn off the system.
CAUTION:
The 120 V AC PSU is not recommended for this system and using the same can cause
system throttling.
CAUTION:
If two PSUs are used, they must be of the same type and have the same maximum
output power.
Locating Service Tag of your system
Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code is and Service Tag are
found on the back of the system by pulling out the information tag. Alternatively, the information may be on a sticker on the chassis of the
system. This information is used by Dell EMC to route support calls to the appropriate personnel.
