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.

| 1 | Failed| Fault | PWR SPLY,750W,RDNT,ARTESYN| 00.1B.53 | *
| 2 | OK | Single | PWR SPLY,750W,RDNT,ARTESYN| 00.1B.53 |
In this example, power supply 1 is identified as failed and should be replaced.
Remove the power supply unit
Before you begin
CAUTION
The system needs one power supply unit (PSU) for normal operation. Since the
DP4400 is a power-redundant system, remove and replace only one PSU at a time in a system
that is powered on.
1. Follow all safety guidelines.
2. Unlatch and lift the optional cable management arm if it interferes with the PSU removal.
Procedure
1. Disconnect the power cable from the power source and from the PSU you intend to remove,
and then remove the cable from the strap on the PSU handle.
2. Press and hold the release latch, and slide the PSU out of the system by using the PSU
handle.
