If DIMMs will not immediately be installed, set the memory airflow guide in position and reinstall the top cover. Refer to “Replacing the Top Cover”.

Installing DIMMs

DIMMs must be installed in groups of 4 (quads), and in specific locations. DIMM sockets are shown in Figure 3-21 “DIMM Slots”. The first quad (4 DIMMs) must be installed in sockets 0A, 0B, 1A, and 1B. The second quad must be installed in sockets 2A, 2B, 3A, and 3B. The third (and final) quad must be installed in sockets 4A, 4B, 5A, and 5B. If DIMMs of different sizes are to be installed, the smallest DIMMs (least memory) must be installed in the first quad. DIMMs in the second quad can be equal to or larger (more memory) than the DIMMs in the first quad. If DIMMs are to be installed in the third quad, they must be equal to or larger than the DIMMs in the second quad.

To install DIMMs, perform the following steps:




	WARNING! Voltages and hazardous energy can be present at various locations within the server whenever a power source is connected. This hazard is present even when the power switch is in the off position. Ensure that the system is powered down and all power sources have been disconnected from the server prior to performing the following procedures.
