Installing the Power Supplies
If you have removed the power supplies prior to mounting the S300 expansion
enclosures, it is important they are re-installed in the same location. This will
preserve the proper module locations for fully stacked systems containing battery
backup units (described later in this chapter).
Installing the First Level Modules
NOTE
It is difficult to set the switches of the first level modules and connect the
RS-485 cables once the stacked modules are installed.
This section describes the installation and wiring of S300 modules. The modules
include input and output modules and reader modules. The wiring instructions are
the same for modules in expansion enclosures.
