3. Unpack the power module and verify that the power module model is correct.
4. Correctly orient the power module with the power module slot (use the letters on the power
module faceplate for orientation), grasp the handle of the power module with one hand and
support its bottom with the other, and slide the power module slowly along the guide rails into
the slot (see callout 1 in Figure2-46).
5. Fasten the captive screws on the power module with a Phillips screwdriver to secure the power
module in the chassis (see callout 2 in Figure2-46). If the captive screw cannot be tightly
fastened, verify the installation of the power module.
The recommended torque is 5 kgf-cm (0.49 Nm).
6. Install the filler panel over the empty power module slot to prevent dust and ensure good
ventilation if you install only one power module.
