Installing the Control Unit

Installing the Basic Carrier

Begin this procedure only if you have met all of the requirements discussed earlier in this chapter.

NOTE:

If you are upgrading a system, the basic carrier (and possibly one or two expansion carriers) is already installed. Do not remove any of these carriers; skip to the next section, “Upgrading the Control Unit.”

Following the instructions given below, mount the basic carrier onto the plywood, leaving 5 inches (12.7 cm) of plywood to the left. This allows easy access to the installation and removal of the system cover, while allowing enough room for system expansion (up to a total of three carriers and

5 inches (12.7 cm) of plywood to the right of the third carrier).

1.Mark the screw hole locations on the backboard using the basic carrier as a guide. See Figure 2-5.

Make sure the carrier is level before marking the holes.
