Installing a power supply
1. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
2. Unpack the power supply and verify that the power supply model is correct.
3. Correctly orient the power supply, 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 until it has firm contact with the connectors on the backplane.
To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If
you cannot insert the power supply into the slot, re-orient the power supply rather than use
excessive force to push it in.
