distance from the front of the switch.
Step 2 If you are installing the chassis into an ungrounded rack, you must attach a customer-supplied grounding wire to the
chassis. However, if you are installing the chassis into a grounded rack, you can skip this step.
Step 3 Install the slider rails into 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 rack-mount brackets, and the other two posts will have the slider rails.
b. Position a slider rail at the desired level side of the rack and use two 12-24 screws or two 10-32 screws, depending
on the rack thread type, to attach the slider rail to the rack. Tighten the 12-24 screws to 30 in-lb (3.39 N·m) of torque,
or tighten the 10-32 screws to 20 in-lb (2.26 N·m) of torque.
c. Repeat Step 2
To make sure that the slider rails are at the same level, you should use a level tool or tape measure, or carefully count
the screw holes in the vertical mounting posts.
Step 4 Insert the switch into the rack and attach it as follows:
M4 screws
for the other rack-mount bracket on the other side of the switch, and be sure to position it in the same
to attach the other slider rail to the other side of the rack.
