Installing a power supply

Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

Unpack the power supply and verify that the power supply model is as required.

Remove the filler panel (if any) from the target slot.

If you require only one power supply, install it in power supply slot 1 and make sure a filler panel is installed in power supply slot 2.

Orient the power supply with the upside up. Grasp the handle of the power supply with one hand and support its bottom with the other, and slide the power supply slowly along the guide rails into the slot. See callout 1 in Figure 18.

To prevent damage to the power supply and the connector on the switch backplane, insert the power supply gently. If you encounter a hard resistance or the power supply tilts while inserting the power supply, pull out the power supply, realign it with the slot, and then insert it again.

Fasten the captive screws on the power supply with a Phillips screwdriver to secure the power supply in the chassis. See callout 2 in Figure 18.

If the captive screw cannot be tightly fastened, examine the installation of the power supply.
