Condition
Blinking green and
turns off
When hot-plugging a PSU, it blinks green five times at a rate of 4 Hz and turns off. This indicates a
PSU mismatch due to efficiency, feature set, health status, or supported voltage.
If two PSUs are installed, verify that:
● Both PSUs have the same type of label. For example, Extended Power Performance (EPP) label.
● The PSUs are of the same type and have the same maximum output power.
Do not mix PSUs from previous generations of servers, even if the PSUs have the same power rating.
This results in a PSU mismatch condition or failure to turn the VxRail on.
CAUTION: Mixed PSUs may cause a PSU mismatch condition or failure to power on the
system.
When correcting a PSU mismatch, replace the PSU with the blinking indicator. Do not swap the PSU
to make a matched pair.
CAUTION: If the PSU is swapped, an erroneous condition may occur and cause an
unexpected system shutdown.
To change from a high output configuration to a low output configuration or conversely, you must
power off the system.
AC PSUs support both 240 V and 120 V input voltages except for Titanium PSUs, which support only
240 V.
CAUTION: When two identical PSUs receive different input voltages, they can output
different wattages and trigger a mismatch.
CAUTION: Do not combine AC and DC PSUs. It is not supported and triggers a mismatch.

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 hot-plugging a PSU, it blinks green five times at a rate of 4 Hz and turns off. This indicates a
PSU mismatch due to efficiency, feature set, health status, or supported voltage.
