16 PowerEdge R940 overview
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.
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
