Installing a DC Power Shelf
Installing the DC Power Input Module
Step 5
From the rear of the chassis, insert the DC power input module (PIM) into the open power bay (see
Figure 2-13
).
Note
The PIM weighs 6.5 lb (2.9 kg).

Step 6
Reinsert the No. 2 Phillips screws taken from the rear power access panels into their respective holes:
one on each side, three in front, and one underneath the chassis.
Installing the DC Power Input Shelf
Caution
The DC power input shelf can only be inserted into the chassis when all power is removed from the
chassis.
Step 7
Go to the front of the chassis. To install the DC power input shelf, follow these steps:
a.
To prepare the chassis for installing the DC power input shelf, remove the inlet grille from the
bottom of the chassis (for the procedure, see the
“Removing the Inlet Grille” section on page 5-3
).
b.
Holding the DC power input shelf underneath with one hand and steadying it with the other, lift the
DC power input shelf up and slide it part way into the power shelf slot on the front (PLIM) side of
the chassis. Be sure to center the DC power input shelf in the slot when you slide it in (see
Figure 2-14
).
Caution
An empty DC power input shelf weighs about 15.5 lb (7 kg). To prevent injury when lifting
the shelf, keep your back straight and lift with your legs, not your back. Avoid sudden twists
or lateral moves.
c.
Slide the DC power input shelf fully into the chassis. Be sure that the lever handles are aligned with
the lever handle catches on the chassis casing.
d.
To lock the power input shelf into position, lift the lever handles up.
