11 Remove the PDU:
Note: When a system is shipped, a set of screws secures the leveling
bracket at the rear of the PDU to protect against vibration during
transit. If the shipping screws were not removed during initial
installation, you must remove them now to pull the PDU out of the
pedestal. Pull the blower unit all the way out of the pedestal so you can
access the shipping screws on the leveling bracket.
a. Loosen the three screws that secure the PDU.
b. Remove the two vertical screws located in the rear of the PDU that
hold the L-bracket to the lower pedestal.
c. Pull the PDU out of the pedestal, being careful to not chafe the
cables against the pedestal.
d. Disconnect the frame ground wire from the PDU at the frame
ground bolt inside the pedestal.
Installing equipment
1 Install the replacement PDU:
a. Connect the frame ground wire from the PDU to the frame ground
bolt inside the pedestal.
