Removing a power supply unit
The procedure for removing AC and DC PSUs is identical.

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/poweredgemanuals.
