Rack-Mount the Chassis on a 2-Post Rack
b) Repeat with the other rack-mount guides on the other side of the router.
Step 4
Install the slider rails to the rack as follows:
a) Position the slider rails at the desired levels 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.
Note
For racks with square holes, you might need to position a 12-24 cage nut behind each mounting hole in a
slider rail before using a 12-24 screw.
b) Repeat with the other slider rail on the other side of the rack.
c) Use a tape measure and level to verify that the rails are at the same height and horizontal.
Step 5
Insert the router into the rack and attach it as follows:
a) Holding the router with both hands, position the back of the router between the front posts of the rack.
b) Align the two rack-mount guides on either side of the router with the slider rails installed in the rack. Slide the
rack-mount guides onto the slider rails, and then gently slide the router all the way into the rack.
Note
If the router does not slide easily, try realigning the rack-mount guides on the slider
rails.
c) Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) through the holes in each
of the rack-mount brackets and into the cage nuts or threaded holes in the rack-mounting rail.
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).
