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 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 or tape measure,
or carefully count the screw holes in the vertical mounting posts.
7. Insert the switch into the rack and attach it as follows:
1.
Fan-tray end of the chassis
3.
Direction of insertion
2.
rack-mount screws
4.
Slider rails
a) Holding the switch with both hands, position the two rack-mount guides on the switch between the
rack or cabinet posts that do not have slider rails attached to them.
b) Align the two rack-mount guides on either side of the switch with the slider rails installed in the
rack. Slide the guides onto the slider rails, and then gently slide the switch all the way into the rack
until the brackets come in contact with two rack or cabinet posts.
Note: If you attached a grounding cable to the chassis, you will need to flex one of the rack-mount
posts slightly to allow the grounding lug to go behind the post.
c) Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) into each
of the two brackets (using a total of four screws), and into the cage nuts or threaded holes in the
rack or cabinet posts.
d) Tighten the 10-32 screws to 20 in-lb (2.26 N·m), or tighten the 12-24 screws to 30 in-lb (3.39
N·m).
