Installing a 1 (RU) Chassis in a Four-post Rack
d) Repeat Steps 1a to 1c for the other front rack-mount bracket on the other side of the switch and be sure to position
that bracket the same distance from the front of the switch.
Step 2
Install the two rear rack-mount brackets on the chassis as follows:
a) Align the two screw holes on a rear rack-mount bracket to the middle two screw holes in the remaining six screw
holes on a side of the chassis. If you are aligning the guide to holes that are near the port connections end of the
chassis, see Callout 3 in the previous figure. Otherwise, see Callout 7 in the previous figure.
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 Steps 2a and 2b 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 (back side of rack) 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.

c) Repeat Steps 3a and 3b 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, use a level tool, tape measure, or carefully count the screw
holes in the vertical mounting rails.
