Removing a power supply unit
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 Dell.com/storagemanuals.
Step
Press the orange release latch and slide the PSU out of the system by using the PSU handle.
