Installing threaded rails

You must install devices that have threaded holes or device rails that have threaded holes on the rail-

mounting flange on the inside of the rack-mounting flanges. See the device documentation for detailed

information about how to use threaded rails.

You must use cage nuts for all optional devices that do not have threaded holes. The rack comes with a

supply of cage nuts, and devices that require them come with cage nuts. Cage nuts are installed on the

inside of the rack-mounting flanges with either the cage-nut-insertion tool or a flat-blade screwdriver. The

cage-nut-insertion tool comes with the rack and some optional devices.

Complete the following steps to install a cage nut with the cage-nut-insertion tool.

nut.
