4. Remove the UPS:
Disconnect all EBMs from the UPS and ensure that the UPS has been
completely shut down.
Remove all the wiring between MBP and UPS, then remove the UPS for
maintenance/replacement.

When removing the 'Cable to UPS', remove top cover of 'UPS ports' only
on the MBP, keep the box of AC input/ AC segment to avoid artificial
electric shock.

During the maintenance/replacement of UPS, it is recommended to install back
the plastic panel to MBP to protect switch suffering an unexpected operation,
causing an artificial electric shock.
