Solution when the power alarm indicator is steady on

Solution when the power alarm indicator is steady on:
1. Locating procedure:
The power alarm indicator is controlled by the PSU hardware, but not the software. If the power alarm indicator is steady on, causes may be as follows:
a. The power supply is normal but the switch on the power plane is turned off.
b. The PSU hardware is faulty.
2. Solution:
a. The switch on the power plane is turned off.
Log in to the storage's OSM management page and check whether related alarms are reported. If no related alarms (PSU or fan) are reported and you can query information about fans and two PSUs on the OSM page, check whether switches on power planes are switched off (you can check whether switches on power planes of controller A and B are the same). If switches on power planes are switched off, turn them on.
b. PSUs are faulty.
If switches on power planes are switched on, internal hardware of PSUs is faulty. In this case, you need to change PSUs.
