3.8 Install the 1RU Device
This section provides information on installing the 1RU Device chassis in 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 or adapt these instructions to suit the rack unit you are using.
WARNING:
The illustrations in Figure 3-4 and Figure 3-5 are for general guidance purposes only.
Always install the Device chassis to the bottom of the rack first to avoid the rack becoming top
heavy.
3.8.1 Identifying the Rack Rail Sections
The 1RU Device chassis includes two rail assemblies in the rack mounting kit. Each assembly consists of two sections: An
inner chassis rail secured to the chassis (front part is factory installed, extension is field installed), an outer rail that secures
to the rack, and an outer rail extension that secures directly to the rear vertical support, Figure 3-1. Each of these assemblies
are designed for mounting universally on the left or right side of the chassis.
NOTE:
This rail will fit a rack between 26” and 33.5” deep.
