Condition
A valid power source is connected to the PSU, and the PSU is operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
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.
indicates a PSU mismatch regarding 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. It results in
a PSU mismatch condition or failure to power on the system.
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
conversely, you must turn off the system.
