Installing A Power Supply; Removing A Power Supply - HP FlexNetwork 5140 EI Series Installation Manual

Installing a power supply

1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Unpack the power supply and verify that the power supply model is as required.
3. 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.
4. 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
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.
5. Fasten the captive screws on the power supply with a Phillips screwdriver to secure the power
supply in the chassis. See callout 2 in
If the captive screw cannot be tightly fastened, examine the installation of the power supply.
