2.3 Installing the Rails
There are a variety of rack units on the market, which may require a slightly different assembly
procedure.
This rail set fits a rack between 26.8" and 36.4" deep.
The following is a basic guideline for installing the system into a rack with the rack mounting
hardware provided. You should also refer to the installation instructions that came with the
specific rack you are using.
Identifying the Rails
The chassis package includes two rail assemblies. Each assembly consists of three sections:
An inner rail that secures directly to the chassis, an outer rail that secures to the rack, and
a middle rail which extends from the outer rail. These assemblies are specifically designed
for the left and right side of the chassis and labeled.

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.
