Installing System Components 1331 Turn off the system, including any attached peripherals, and disconnectthe system from the electrical outlet.2 Open the system. See "Opening the System" on page 84.3 Position the module so the tabs on the underside of the tray fit into thehooks on the front-chassis assembly, then lower the opposite edge of thecard into place. See Figure 3-22.4 Connect the internal dual SD module cable to the connector on thecontrol panel board.5 Close the system. See "Closing the System" on page 85.6 Reconnect the system to its electrical outlet and turn the system on,including any attached peripherals.ProcessorsThe system supports one-, two- and four-processor configurations. In one- ortwo-processor configurations, processors are installed in sockets 1 and 2, andFlexMem Bridges are installed in processor sockets 3 and 4 to enable theprocessors to access the adjacent memory set. For more information oninstalling a FlexMem Bridge, see "Installing a FlexMem Bridge" on page 141.Table 3-5 provides a guide for one-, two-, and four-processor configurations.Table 3-5.
