that unit. If you are adding a module anywhere below the 5U

Library Control Module, position the nut clip (or cage nut) at the

upper hole in that unit.

b If you are adding a module directly above a previously racked

5U Library Control Module, count five full units from the

location of the 5U Library Control Module’s rack ears, and

prepare to install the nut clip (or cage nut) to that location on the

rack.

For example, if the 5U Library Control Module’s rack ears are

located at 1U and 2U, then the nut clips (or cage nuts) should be

installed at 6U and 7U.

Next, determine which holes you must use within the 6U and 7U

markers. Notice that each rack unit, as delineated by the

alignment markers in the rack, contains three mounting holes. If

you are adding a module anywhere above the 5U Library Control

Module, position the nut clip (or cage nut) at the middle hole in

that unit. If you are adding a module anywhere below the 5U

Library Control Module, position the nut clip (or cage nut) at the

upper hole in that unit.

3 Install the nut clips (or cage nuts) to the desired location in the rack.

Installing nut clips:

a Hold the nut clip so that its semi-circle design faces outside the

rack.

b Push the nut clip onto the rack’s mounting holes so that the nut is

behind the rack’s holes. (After the nut clip is installed, you can

slide it up and down the mounting holes, if necessary.)

Installing cage nuts:

a Hold the cage nut so that its hinges face outside the rack, and so

that its hinges clasp the upper and lower portions of the square

hole.

b Place the cage nut in the desired hole. Insert one hinge in the hole

first, then pinch the cage nut and push it into the hole until it

snaps into place. (You may want to use a screwdriver to help

push the hinge into the hole.)

4 Prepare the module to be stacked in the rack.

a Power off the module and disconnect all power cords, network

data cables, and module-to-module cables.
