Common faults and troubleshooting for PSUs

Symptom

Possible Cause

Measure

The Power indicator (green)
is off.

No AC input

Check whether the AC input
is abnormal.

PSU fault

Replace the PSU.

The Alarm indicator
(yellow) is steady on.

Overtemperature protection



The ambient temperature
exceeds the upper
threshold. Increase the
cooling capacity of the
air conditioner.



The air channel is
blocked. Unblock it.

AC input overvoltage or
undervoltage protection

Check whether the AC input
is abnormal.

The Alarm indicator
(yellow) is blinking.

PSU communication failure

Clean the connector in
the rear of the faulty
PSU.

If the fault persists,
replace the ECC800
subrack.
