Chapter 3 Installing the Switch
Rack-Mounting the Switch
Note Figur e 3-1 illustrates how to attach the front of the switch to the rack. You will also need to
attach the rear of the switch to the rack.
Step 2 Attach the left and right L brackets using the 12 M4 Phillips pan-head screws (six on each side) provided
in the rack-mount kit. (See Fig ur e 3-1 .)
Note that the L brackets connect the chassis to the rack. You can mount the L brackets to the front or rear
mounting holes of the chassis, depending on which end is in the front of the rack.
Note Some equipment racks provide a p ower strip al ong the l ength of one of the r ear posts. I f the rack
has this feature, consider the position of the strip when planning fastener points. Before
installing the L brackets on the chassis, determine whether to install the chassis from the front
or the rear of the rack.
Step 3 Slide the rear brackets into the front brackets. (See Figure 3-1.)
