You might need to attach mounting hardware to the rack.
Follow these steps to complete this task. In addition to information
intended to promote safety and reliable operation, this section also
includes illustrations of the related hardware components and shows
how these components relate to each other.
Important: The rail installation
can be completed by one person. However, the installation is easier
if one person is positioned at the front of the rack and one person
is positioned at the rear of the rack. You will also need two people
later in this procedure to install the enclosure into the rack.
CAUTION:
Installing the rails in the rack is
a complex procedure. To install the rails correctly, you must complete
each task in the following order. Failure to do so might cause rail
failure and potential danger to yourself and the system unit.
To
install the mounting hardware into the rack, complete the steps that
follow:
- Facing the front of the rack, locate the two marks
that were made previously on the Electronic Industries Alliances (EIA)
strips.
Note: To install the rails in the limited rack
space for this enclosure model, ensure that you have open workspace
either directly above or directly below the EIA location that you
have marked. If the rack spaces directly above and below the EIA location
currently contain hardware, choose one of the following options to
increase the workspace:
- If the hardware unit directly above or below the EIA location
can be slid into a service position, do so now to provide more workspace.
- Remove the hardware unit either directly above or below the EIA
location to provide more workspace, and reinstall it following the
rails installation.
- Select a rail. Identify the side of the rack where
the rail must be mounted by holding the rail inside of the open space
of the rack as follows:
- The rail points from front to rear.
- The tension clip (A) points toward the
front of the rack and aligns with the bottom EIA hole that you marked
previously, as shown in Figure 1.
- The rail shaft is aligned with the inside edge of the front rack
flange with its open side facing inward.
- Push up the tension clip (A) and
insert it into the bottom EIA hole that you marked previously, as
shown in Figure 1.
Ensure that the lip of the clip is brought fully through the hole
and clasped against the bottom of the hole. Seat the alignment screw (B) in
the middle EIA hole that you marked previously.
Note: There are two
sizes of alignment screws (B). If your rack
has round mounting holes, use the smaller alignment screw for each
rail. If your rack has square mounting holes, use the larger alignment
screw for each rail. Alignment screws are provided with the rack installation
kit.

front of the rack
- At the rear of the rack, locate the two marks that
you made previously on the EIA strips. Compress the rail (C) as
shown in Figure 2,
and then expand the rail carefully toward the marks until the rail
end meets the rear rack flange.

the rail to the rear of the rack
- Seat the alignment screw (D) of
the rail into the middle EIA hole that you marked previously, as shown
in Figure 3.
Figure 3. Mounting the rail to the rear of the rack
- Insert a mounting screw (E) through
the bottom EIA hole, attaching the rail to the rear of the rack as
shown in Figure 3.
- Repeat step 3 through
step 6 for the
other rail.
- At the rear of the rack, hold the cable management
bracket up to the rear rack flanges, aligning the mounting holes on
the bracket to the top holes of the EIA that contains the enclosure,
as shown in Figure 4.
Apply the M5 screws (E) through the mounting
holes of the bracket and into the top EIA holes on the rack flanges.
CAUTION:
To provide for the secure attachment of the rails,
the M5 screws (E) must be applied at the specified
EIA locations even if you do not mount the cable management bracket.
