Chapter 3 Installing the Switch
Rack-Mounting the Switch
NoteFigure 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 2Attach 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 Figure 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.
NoteSome equipment racks provide a power strip along the length of one of the rear posts. If 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 3Slide the rear brackets into the front brackets. (See Figure 3-1.)
