2 Determine where in the rack to install the nut clips (or cage nuts).
Note: Consider using the following method to determine where to install
the nut clips (or cage nuts), rather than adding the module to the
rack first. If you add the module to the rack first, installing the nut
clips (or cage nuts) can be difficult, because rack space has become
restricted.
• If you are adding a module above a previously racked expansion
module, count 9 full units from the location of the expansion module's
rack ears, and prepare to install the nut clip (or cage nut) to that
location on the rack.
For example, if the expansion module's rack ears are located at 1U and
2U, then the nut clips (or cage nuts) should be installed at 10U and 11U.
Next, determine which holes you must use within the 10U and 11U
markers. Notice that each rack unit (U), as delineated by the alignment
markers in the rack, contains 3 mounting holes.
• If you are adding a module anywhere above the 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 control module, position the
nut clip (or cage nut) at the upper hole in that unit.
• If you are adding a module directly above a previously racked control
module, count 5 full units from the location of the 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 control module's rack ears are located at 1U and 2U,
the nut clips (or cage nuts) should be installed at 6U and 7U.
3 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 3 mounting holes.
• If you are adding a module anywhere above the 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 control module,
position the nut clip (or cage nut) at the upper hole in that unit.
4 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.
