7. Equipment Installation
7.1 Installing or Removing Cage Nuts
Warning: Do not install equipment until you have stabilized the enclosure. Install heavier equipment first towards the bottom of
the enclosure. Install equipment starting from the bottom of the enclosure and proceed toward the top of the enclosure - never
the reverse. If using sliding equipment rails, be careful when extending the rails. Do not extend more than one set of sliding
equipment rails at one time. Avoid extending sliding equipment rails near the top of the enclosure.
Note:
The unit comes with two different kinds of screws for equipment installation, black and silver. Use the black mounting screws if you are securing your equipment to
the square hole side of the mounting rail. Use the silver screws if you are securing your equipment to the tapped hole side of the mounting rail.
Note:
The square holes in the middle of each rack unit are numbered and also include a small notch to aid identification. A single rack unit includes the space occupied
by the numbered hole and the holes directly above and below.
To Remove Cage Nuts, Reverse Steps 1-3
Note:
You may wish to use a cage nut tool (user-supplied) to aid cage nut installation and removal.
WARNING: The flanges of the cage nuts should engage the sides of the square opening in the rail, not the top and bottom. Follow
the instructions in your equipment documentation to ensure proper installation of your equipment.
1
Locate the numbered square openings in
the mounting rails where you plan to install
your equipment. You will install cage nuts
(included) into the square openings in order
to provide an attachment point for the
mounting screws (included).
Note:
Consult your equipment documentation to
determine how many cage nuts will be required
and where they will need to be installed.
2
From the inside of the mounting rail, insert
one of the flanges of the cage nut through
the square opening. Press it against the
side of the square opening. Each flange
should engage one side of the square
opening, not the top or bottom.
3
Compress the cage nut at the sides slightly
to allow the remaining flange to fit through
the square opening. When the cage nut is
properly installed, both flanges will protrude
through the square opening and will be
visible on the outer surface of the mounting
rail. Repeat steps 1-3 until all required cage
nuts are installed.
7.2 Alternate Mounting: Tapped Hole Mounting Rail
Warning: Do not attempt to adjust rails while equipment is installed in the enclosure. Do not attempt to use rails without screws
installed. (2 per rail.)
The 2 mounting rails are pre-installed for securing equipment using the square hole side of the mounting rail. To switch to the tapped hole side of the
mounting rail, follow the steps below:
1
Each rail is connected to the enclosure with
2 screws: 1 in the upper corner and another
in the lower corner. Using a Phillips-head
screwdriver, remove the screws that fasten
the rails to the enclosure.
2
Switch the rail locations. Ensure the tapped
hole side of each rail is facing the front
door.
3
Reattach the mounting rails.
