FIGURE 1. CHS-6 CHASSIS:
The BB-XP cabinet has a built-in chassis that will accommodate one or two
XP6-R modules.
FIGURE 2. BB-XP CABINET:
The front XP6-R module positions of each chassis are offset below the rear
XP6-R module positions so that all of the status indicators are visible.
Cabinets
A BB-25, CAB-3 or CAB-4 Series cabinet will house the CHS-6 chassis with up
to six XP6-R modules installed on it. Refer to cabinet installation documents
for dimensions.
The BB-XP cabinet houses one or two XP6-R modules on the internal chassis
that is part of the cabinet. Refer to cabinet installation documents for dimen-
sions.
INSTALLATION STEPS
1. Cabinet Mounting
In a clean, dry area, mount the backbox using the four holes provided in the
back surface of the cabinet.

2. Chassis Installation
The CHS-6 chassis is mounted in the BB-25, CAB-3 or CAB-4 Series cabinets. It
is shipped with two self-threading screws, which are used to fasten the chassis
to the back wall of the cabinet (see Figure 4).

The BB-XP cabinet comes with the chassis already installed, so no mounting
is necessary.
3. Module Installation
There are two methods for installing a module in the rear position of a chas-
sis. Method one is for installation of a rear module only, when no module will
be installed in front of it. Refer to Figure 5 for instructions. Method two is for
installation of a rear module when another module will be installed in the
chassis position in front of it. Refer to Figures 6a and 6b for method two. All
necessary screws and standoffs are supplied with the modules.

Step 1: Insert the bottom of the XP6-R module down into a rear slot on the
chassis.
Step 2: Carefully swing the upper edge of the board back towards the back of
the chassis until it touches the two standoffs.
Step 3: Align two 4-40 screws with the two standoffs and tighten.
Step 4: Address and wire the modules according to the instructions in this
manual.
The steps in Figures 6A – 6C describe and illustrate module installation when
the rear chassis position and the position in front of it will be filled. Front
position installation is possible only if the rear position is filled with an XP
module.
