Chapter 3 Installing the Switch
Rack-Mounting the Switch
Note Figure 3-2 illustrates how to attach the front of the switch to the rack. You
can also attach the rear of the switch to the rack, depending on the
configuration of your rack.
Step 2 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 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.
Attach the left and right L brackets using the M4 Phillips flat-head screws
provided in the rack-mount kit. (See
Figure 3-2.)
