If your rack has wide hole spacing (see Figure 1-3), mark the lower and middle
5
mounting positions on the vertical rails as shown by the bottom and middle
V-notches on the sides of the template.
Each 1-U (1.75-inch) vertical space on a rack with wide hole spacing has two holes
with center-to-center spacing between holes (beginning at the top of a 1-U space) of
1.25 inches (see Figure 1-3).
Installing the Slide Assemblies in the Rack
You can install the slide assemblies in a 2-post open-frame rack having either universal-hole
spacing (see Figure 1-2) or wide hole spacing (see Figure 1-3). You can install the 2-U
RapidRails in either a flush-mount or center-mount configuration.
CAUTION: The 2-U RapidRails rack kit is designed to support a single system in a
2-post open frame relay rack. Do not attempt to install any other system using
this kit. Damage to the system and personal injury to you and others may result.
Center-Mount Installation
To prepare the RapidRails slide assemblies for center-mount installation in the 2-post rack,
perform the following steps:
Using a 3/8-inch nut driver, loosen by one-half turn the two locking nuts that attach
1
the center bracket to each slide assembly.
Center the alignment hole on the bracket with an appropriate alignment hole on each
2
slide assembly. There is an alignment hole on each movable bracket(see Figure 1-12).
Position the right slide assembly in the two-post rack at the location you marked,
3
adjust the front and rear brackets tightly against the vertical two-post rack and secure
the front and rear center mounting brackets to the rack with two 12-24 x 0.5-inch
pan-head Phillips screws.
Repeat step 3 to install the left slide assembly in the rack.
4
Using a 3/8-inch nut driver, tighten the locking nuts on the center mounting brackets
5
of both right and left slide assemblies (see Figure 1-11).
