Installing the L Brackets in a rack
Note In many older equipment racks, the rack posts are prethreaded to accept either 10-32 or 12-24 screws. Newer
rack enclosure posts might not be prethreaded. These rack enclosure posts require that you install 10-32 or
12-24 clip nuts or cage nuts to secure the rack-mount screws. The clip nuts or the cage nuts are not included
as part of the accessory kit and must be obtained on your own.
Before you install the shelf brackets, determine the clearance between the insides of the left and right rails of
