2.3 Installing the Rails

This section provides information on installing the chassis into a rack unit with the rails
provided. There are a variety of rack units on the market, which may mean that the assembly
procedure will differ slightly from the instructions provided. You should also refer to the
installation instructions that came with the rack unit you are using. Note: This rail will fit a
rack between 26.8" and 36.4" deep.

Overview of the Rack Rails

The package includes two rail assemblies. Each is specifically designed for the left or right
side of the chassis, and so marked. Each rail consists of two sections: a front section which
secures to the front post of the rack and a rear section which adjusts in length and secures
to the rear post of the rack.

Note: Both front chassis rails and the rack rails have a locking tab, which serves two functions.
First, it locks the server into place when installed and pushed fully into the rack (its normal
operating position. In addition, these tabs lock the server in place when fully extended from
the rack. This prevents the server from coming completely out of the rack when pulled out
for servicing.
