NovaScale R422 Installation and User's Guide
2-4 Installing the System into a Rack
This section provides information on installing the NovaScale R422/R422-INF server into
a rack unit with the rack rails provided. If the system has already been mounted into a
rack, you can skip ahead to Sections 2-5 and 2-6 . There are a variety of rack units on the
market, which may mean the assembly procedure will differ slightly. You should also refer
to the installation instructions that came with the rack unit you are using.
Identifying the Sections of the Rack Rails
You should have received two rack rail assemblies in the rack mounting kit. Each assembly
consists of two sections: an inner fi xed chassis rail that secures directly to the server chassis
and an outer fi xed rack rail that secures directly to the rack itself (see Figure 2-1). Two pairs
of short brackets to be used on the front side of the outer rails are also included.
Installing the Inner Rails
Both the left and right side inner rails have been pre-attached to the chassis. Proceed to the
next step.

Installing the Outer Rails
Begin by measuring the distance from the front rail to the rear rail of the rack. Attach a
short bracket to the front side of the right outer rail and a long bracket to the rear side of
the right outer rail. Adjust both the short and long brackets to the proper distance so that
the rail can fi t snugly into the rack. Secure the short bracket to the front side of the outer rail
with two M4 screws and the long bracket to the rear side of the outer rail with three M4
screws. Repeat these steps for the left outer rail.
Locking Tabs
Both chassis rails have a locking tab, which serves two functions. The fi rst is to lock the
server into place when installed and pushed fully into the rack, which is its normal position.
Secondly, these tabs also lock the server in place when fully extended from the rack,
This prevents the server from coming completely out of the rack when you pull it out for
servicing.
