Condition

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

handle blinks green.

CAUTION

Do not disconnect the power cable, or unplug the

PSU when updating firmware. If a 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 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, the Extended

Power Performance (EPP) label. Mixing PSUs from previous

generations of systems based on 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

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. AC PSUs support

both 240 V and 120 V input voltages except for Titanium

PSUs, which support only 240 V. When two identical PSUs

receive different input voltages, they can output different

wattages and trigger a mismatch.

CAUTION

If two PSUs are used, they must be of the same

type and have the same maximum output power.

CAUTION

Combining AC and DC PSUs is not supported and

triggers a mismatch.
