Installing the Switch using the NXK-ACC-RMK-2RU Rack-mount Kit
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 slide it into the front-mount bracket already
installed and secure with 12-24 screws or 10-32 screws, depending on the rack thread type (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.
c) Repeat Step 3 to attach the other slider rail to the other side of the rack.
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:
a) Holding the switch with both hands, position the switch onto the rack-mount brackets and carefully slide the chassis
into the rack (see the following figure).
