Installing Expansion Carriers

If one or more expansion carriers is indicated for the system, follow this
procedure to mount each one (see Figure 2-8).
1. If you are adding an expansion carrier to an existing system, see the
previous section before continuing.
2. 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 extenders and connectors on the carriers.

3. Align the connector of the expansion carrier with the card extender on
the previously mounted carrier and slide the connector onto the
extender.
4. Mark the screw hole locations on the backboard using the expansion
carrier as a guide. Make sure the carrier is level before marking the
holes.
