Installing Expansion Carriers

If you are adding an expansion carrier to an existing system, see “Upgrading the Control Unit” in Chapter 9 before continuing.

If you are to install one or more expansion carriers, follow the steps below to mount each one. Refer to Figure 2–9 and Figure 2–5 throughout the procedure.

! Locate the breakaway plastic tab on the right side of the previously mounted carrier. Using a flat-blade screwdriver, gently pry the tab open to expose the card extender.

! Align the connector of the expansion carrier with the card extender on the previously mounted carrier and slide the connector onto the extender.

! Mark the screw-hole locations on the backboard, using the expansion carrier or the template that comes with the preassembled plastic backboard as a guide.

Make sure the carrier is level before marking the holes.

! Disconnect the expansion carrier connector from the previously mounted carrier and put the expansion carrier aside.

! Drill a pilot hole in the center of each of the four screw-hole marks.

! Anchor the screws approximately halfway into the backboard.

! If housing clips are to be installed on the housing and this is the last carrier in the control unit, place the housing clips around the right-hand molding for the screws on the back of the carrier.

If not, go to Step 8.

! Position the expansion carrier on the screws and slide it to the left, to reconnect the expansion carrier card extender to the previous carrier’s connector.

! Make sure the connection is secure.

! Make sure the carrier is level and the housing clips extend as far as possible from the right side of the carrier.

! Tighten the screws.
