This section contains information on how to install DIMMs on the 8 GB memory board. If you are not installing an 8 GB Memory Board, go directly to the next section of this
manual, “Gaining Access to the Card Cage”. If the customer ordered an 8 GB Memory
Board, you will have to install DIMMs on a memory carrier board before installing the
board in the PMB card cage.


Each memory carrier board is divided into quadrants. Each quadrant comprises eight
DIMM sockets. Refer to Figure 1-1. Socket locations in each quadrant are numbered.
Socket location numbers for quadrants on the left side of the memory board are numbered
on the left side of each socket. Socket location numbers for quadrants on the right side of
the memory board are numbered on the right side of each socket.
DIMMs are installed in each quadrant according to the following rules:


DIMMs are installed on the carrier board in sets of four. Each DIMM in a set must be installed in a different quadrant. (After all of the DIMMs are installed, there should always be an equal number of DIMMs in each quadrant.). The first DIMM in a set can be installed in any unoccupied position in any quadrant.The initial location in which a DIMM is installed determines where the remaining three DIMMs in the set must be installed in the other three quadrants. For example, if you install a DIMM in location 1A, the remaining three DIMMs in the set must be installed in locations 1B, 1C, and 1D. Likewise, if you install the first DIMM in a set in location 7A, then the remaining three DIMMs must be installed in locat.
