Installing the Switch
b) Attach the guide to the chassis using two M4 screws (see Callout 4 or 8 in the previous figure). Tighten the screws
to 12 in-lb (1.36 N·m) of torque.
c) Repeat Step 2 for the other rear rack-mount bracket on the other side of the switch.
Step 3 Install the slider rails on the rack or cabinet as follows:
a) Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the
rack or cabinet, two will be used for the front mount brackets attached to the easiest accessed end of the chassis, and
the other two posts will have the slider rails.
b) Position a slider rail at the desired level on the back side of the rack and use two 12-24 screws or two 10-32 screws,
depending on the rack thread type, to attach the rails to the rack (see the following figure). Tighten 12-24 screws to
30 in-lb (3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque.

To make sure that the slider rails are at the same level, you should use a level tool, tape measure, or carefully count
the screw holes in the vertical mounting rails.
Step 4 Insert the switch into the rack and attach it as follows:
