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.

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.
