You need the following tools and part to perform this task:
• ESD-preventive wrist strap
• 3/8-in. ratchet wrench with 10-mm socket
• 3/8-in. ratchet wrench with 8-mm socket or open (box end) wrench

Steps
To install a PDU, perform the following steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets on the rear (MSC) side of the chassis or a bare metal surface on the chassis.
Step 2 Make sure that the PDU is unplugged.
Step 3 Grasp the PDU by the side and set it carefully into place in a PDU slot on the rear (MSC) side of the
chassis. Be sure to lift the PDU over the lip on the edge of the chassis, and align the guide pins on the
chassis with the guide holes on the PDU.
Caution Do not lift the PDU by the power cord—doing so can damage the PDU or the cord.
Step 4 If needed, put the second PDU into place in the other PDU slot on the chassis.
Note The PDU holding plate bolts to both PDUs and the side of the interior of the chassis.
Step 5 Install the PDU holding plate.
a. Slide the holding plate into place on top of the PDU, using the guide bolts on the side of the chassis
to place it correctly.
b. Use the socket wrench to bolt the holding plate to the top of the PDUs with the eight 10-mm bolts
(four for each PDU).
c. Use the socket wrench to bolt the holding plate to the interior of the side of the chassis with the four
8-mm bolts (two for each side).
Step 6 Use the socket wrench to install the 8-mm center holding bolt and the 10-mm nut.
