2-8 Setting Up the System
! To improve rack stability, mount the BSU towards the bottom of the
rack cabinet.
! If there are units already installed, install the BSU into the next empty
space from the bottom of the rack cabinet.
2. Starting at the bottom of the rack cabinet, or at the top or bottom of a
previously mounted unit, measure the number of screw hole locations on the
front vertical mounting rails (see Figure 2-4) and rear vertical mounting rails
(see Figure 2-5) for the Rack Mounting Bracket Assemblies and Cable
Retention Arm. Mark the location with a pencil on the outside of both the
front and rear vertical mounting rails.
Note: For vertical reference, every three screw holes on
the rack vertical mounting rail are equal to 1U (1.75 inches).
