2.3 Installing the Rails
This section provides information on installing the CSE-HS119-R000NP2 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.
Identifying the Rails
The CSE- HS119- R000NP2 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.
Figure 2-1. Identifying the Outer Rail, Middle Rail and Inner Rail
Note: Both front chassis rails and the rack rails have a locking tab, which serves two
functions. First, it locks the chassis into place when installed and pushed fully into the rack
(its normal operating position). In addition, these tabs lock the chassis in place when fully
extended from the rack. This prevents the chassis from coming completely out of the rack
when pulled out for servicing.
