Add-On Expansion Module Installation
Each add-on expansion module measures 15.5 wide x
9.4 high x 1.6 wide and weighs approximately 4
pounds. The modules are designed so that you can
attach them to the base unit and connect them to it via
cabling.
[q
You must always connect the first module
to the top location on the base unit.
To install an expansion module to a base unit, refer to
Figure 3-15 and perform the procedure detailed in
steps 1 - 11.
NOTE: If you p/an to a/so up-grade the system
software at the same time that you add
expansion modules, be sure to add the
. expansion modules first by following steps 1
through 7 1. After you have installed the
expansion modules and programmed for the
new stations and line ports, you can then
up-grade the software as described in the
