Connecting to Expansion Port 3
Expansion Port 3 is incorporated into the 100-pin multi-function socket J2 on the main logic
board. See Section 6.4.4 on page 98 for more information on the 100-pin connector.
To connect to the 100-pin socket, align the pins of the connector to the socket and press down
firmly and evenly across the entire connector.
