Installing Expansion Carriers
If you are adding an expansion carrier to an existing system, see
the Control Unit''
If you are to install one or more expansion carriers, follow the steps below to
mount each one. Refer to
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.
