2. Disconnect the power cable from the power outlet and from the PSU that you intend to remove.
3. Remove the cable from the strap on the PSU handle.
4. Unlatch and lift or remove the optional cable management accessory if it interferes with the PSU removal.
NOTE:
For information about the cable management when the PSU is removed or installed while the system is in a rack,
see the system’s cable management arm documentation at https://www.dell.com/poweredgemanuals.
