CAUTION: The DM5500 needs one power supply unit (PSU) for normal operation. On power-redundant systems, remove and replace only one PSU at a time in a DM5500 that is powered on. The DM5500 supports either 1100W PSUs or 1600W PSUs, depending on the country where it is installed. When you are replacing a PSU, make sure that both PSUs are the same wattage.
Identify the failed power supply unit by using one of the following methods:
Check the
Alerts page in the Data Manager Appliance UI.
Using SSH, log in to the DM5500 command line interface (CLI) with admin privileges.
Use the
admin username and the DM5500 password.
At the command line, type the following command:
# system showfru Power
The screen displays that the system is collecting data. When the data collection is completed, the screen displays status information for the power supply units. Check which power supply unit has failed and requires replacement.
Example command output:

In the above example, power supply unit 2 is the failed power supply unit.
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.
Steps
Press the release latch and slide the PSU out of the system by using the PSU handle.
