Installing support rails for 2U expansion enclosures
Before you install 2U expansion enclosures, you must first install support rails.
Procedure
To install the support rails, complete the following steps.
1. Locate the expansion enclosure rails (Figure 13 on page 17).
The rail assembly consists of two rails that must be installed in the rack cabinet.

2. Locate the hardware that is used to install the rails, including two rail springs, two sets of eight
bracket pins, and two M5 screws.
Set the hardware aside for use later in the installation process.
3. Install a spring on each rail.
a) Extend the rail to its full length.
b) Push one looped end of a spring over one stud on the inside of the rail.
c) Stretch the spring slightly and push the other looped end of the spring onto the other stud on the
inside of the rail.
4. Working at the front of the rack cabinet, identify the two standard rack units (2U) of space in the rack
into which you want to install the support rails.
Figure 14 on page 18 shows two rack units with the front mounting holes identified.
