Removing a power supply unit
The procedure for removing AC and DC PSUs is identical.
Prerequisites
CAUTION: The system needs one power supply unit (PSU) for normal operation. On power-redundant systems,
remove and replace only one PSU at a time in a system that is powered on.
1. Follow the safety guidelines listed in Safety instructions.
2. 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.
3. Unlatch and lift the optional cable management arm if it interferes with the PSU removal.
For information about the cable management arm, see the system’s rack documentation at www.dell.com/
poweredgemanuals.
Steps
Press the orange release latch and slide the PSU out of the system by using the PSU handle.

Installing a power supply unit
The procedure for installing AC and DC PSUs is identical.
Prerequisites
1. Follow the safety guidelines listed in Safety instructions.
2. For systems that support redundant PSU, ensure that both the PSUs are of the same type and have the same maximum
output power.
NOTE: The maximum output power (shown in watts) is listed on the PSU label.
