To install a DIMM card

Note: There must be at least one DIMM installed in the BCM main unit for the system to
function.
Warning: Protect the hardware components against damage from electrostatic discharge.
Always wear a grounded wrist strap before you handle components. Always place the
components in a static-free container.
1 Position and correctly align the new DIMM (edge connectors first) into the connector.
Note: The DIMM has two notches on the edge connector. Position the DIMM so
that one of the notches is on the side of the slot nearest to the BCM cards.
2 Carefully and firmly press down on the top of the DIMM card with your thumbs. At the same
time, use your index fingers to move the fastening tabs inward toward the card. When the card
is completely inserted in the connector, the fastening tabs clip to the side of the DIMM card.
