Removing an LPU

1. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
2. Use a Phillips screwdriver to completely loosen the captive screws at both sides of the LPU.
3. Pull the ejector levers at both sides of the LPU outward, and pull the LPU along the guide rails until
it completely comes out of the switch chassis.
Do not use excessive force during the operation.
4. If no new card is to be installed, install the blank panel to prevent dust and ensure good ventilation
in the switch.
