Condition
CAUTION
AC PSUs support both 240 V and 120 V input voltages with the
exception of 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.

Identifying a failed power supply from the ACM
If a power supply is suspected of failing, you can check the web UI or use the FRU
command line verification from the ACM.
Procedure
1. Access the IDPA web UI and check for alerts in the Health screen. Click an alert
for more details.
2. Log in to the ACM command line by using SSH.
Use
root
for the user, and use the common password for the appliance.
3. At the command line, type the following command:
# showfru power
The screen displays that the system is collecting data. When the data collection
is completed, a screen similar to the following displays status information for
the power supplies.
