When you apply power, the Power LED on the switch front panel lights. If your switch
supports two PSUs, either the Power 1 LED or Power 2 LED on the switch front panel
lights, depending on which PSU you installed. If the Power LED does not light, make
sure that the power cord is plugged in correctly and that the power source is good.

Replace a half-width switch in a rack

This step describes how to replace a half-width switch that is mounted next to a second
half-width switch on a rack.
You can skip this procedure if the middle mounts are already secured in the rack with
screws.
Note: The switch that shares the same rack as the switch being replaced can remain
operational during this procedure.
WARNING: Make sure to add a support beneath the half-width switches when removing
or installing a half-width switch. The support keeps the switches level while the mounting
screws are loosened to avoid damage to both the switch and the middle mount screws.
