Install the dual in-line memory module (DIMM) card
Use this procedure to install a replacement DIMM or when you want to increase the amount of
RAM in the Business Communications Manager.
1 Position and correctly align the new DIMM (edge connectors first) into the connector.
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.

Continue to the next step of this procedure when complete.

5 Install the WAN card (if applicable). See “Install the WAN card” on page 221. Continue to the
next step of this procedure when complete.
6 Connect the DS30 connectors to the MSC.
7 Completely install the base function tray in the platform base chassis (see “Install the base
function tray” on page 151). Ensure you do not pinch or damage any cables.
8 Install the base function tray bezel. See “Install the base function tray bezel” on page 154.
Continue to the next step of this procedure when complete.
9 Insert all connectors in the correct locations on the base function tray face.
10 Restore the Business Communications Manager to operation. Refer to “Restart the System
after Maintenance” on page 147 for details. Continue to the next step of this procedure when
complete.
11 This procedure is complete.
Note: There must be at least one DIMM installed in the Business Communications
Manager in order for the system to function.
Warning: Protect the hardware components against damage from electro-static
discharge. Always wear a ground wrist strap before you handle components. Always place
the components in static-free container.
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 Business
Communications Manager cards.
Note: Do not force the DIMM into its slot. If the DIMM does not slide in easily,
check the alignment of the DIMM.
