Installing the expandable rails and extension bracket into
the rack
You might need to install rails into the rack. Use the
procedure in this section to perform this task. In addition to related
safety information, this section also includes illustrations of the
related hardware components and shows how these components relate
to each other.
Attention: Installing the rails in the rack
is a complex procedure. To install the rails correctly, you must perform
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 expandable rails into the rack, complete the following
steps:
Loosen the two screws (B) in the
middle of both rails (A) to allow each rail
to extend.
Figure 1. Extending the system
rails
Starting at the back of the rack, extend the left rail
and insert the rail pins (C) into the marked
locations the rack so that it is facing upward (L shape).
Tip: Although the rail installation can be completed by one
person, for ease of installation, one person can be positioned at
the front of the rack and one person at the back of the rack.
From the back of the rack, extend the right rail and insert
the rail pins (C) into the marked locations.
Move to the front of the rack, extend the left rail and
insert the rail pins (C) into the marked locations.
Extend the right rail and insert the rail pins (C) into
the marked locations.
Using one M5 screw (D), secure the
left rail to the front of rack into the lower location (E).
Important: Do not install a screw in the top location
at this time. It will secure the shell to the assembly.
Figure 2. Attaching the system rails to the front of
the rack
Using one M5 screw (D), secure the
right rail to the front of the rack into the lower location (E).
Insert two nut clips at the marked location on the front-left
rail of the rack.
Insert two nut clips at the marked locations on the front-right
rail of the rack.
Move to the back of the rack and insert two nut clips at
the marked locations on the back-left rail of the rack.
Insert two nut clips at the marked location on the back-right
rail of the rack.
If you are installing a 5790 expansion unit,
secure each extension bracket (F) through the
rack and into each rail using three M5 screws (G).
Note: Each bracket will face inward.
Figure 3. Attaching
the extension brackets and rails to the back of the rack
If you are installing a 5796 expansion unit,
use three M5 screws (G) to secure each rail
arm and bracket (F) to the rack.
Note: Each
bracket will face inward.
Figure 4. Attaching the rails to
the back of the rack
Tighten the two screws (B) in
the middle of the left rail and the two screws (B) in
the middle of the right rail. Refer to Figure 1.
