Removing A Power Supply - Allied Telesis AT-8400 Series Reference Manual

Removing a Power Supply

You can remove or replace a power supply from an AT-8400 chassis
without having to power off the switch. To remove a power supply,
perform the following procedure:
1. Using a Phillips screwdriver, loosen the two captive screws that
secure the power supply cover to the chassis and remove the cover.
You remove the cover by angling it from the bottom as you slide it
down and out of the chassis.
