Description
Blank filler cover the AC-socket opening, when power supply
cables from the front of the chassis.
Kensington lock slot for securing the chassis.
Condition
Indicates that a valid power source is connected to the PSU
and the PSU is operational.
Indicates an issue with the PSU.
Indicates that the power is not connected to the PSU.
Indicates that the firmware of the PSU is being updated.
CAUTION:
Do not disconnect the power cord or
unplug the PSU when updating firmware. If firmware
update is interrupted, the PSUs will not function.
When hot-plugging a PSU, it blinks green five times at a rate
of 4 Hz and powers off. This indicates a PSU mismatch due 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 power on the system.
CAUTION:
If two PSUs are used, they must be of
the same type and have the same maximum output
power.
