Installing and Removing DIMMs
DIMM Installation Guidelines
Each installed memory box must have either four or eight DIMMs installed, as shown below.
•Four DIMM installation: Install DIMMs in JD0B1, JD0A1, JD2B1, JD2A1
•Eight DIMM installation: DIMMs installed in each socket
Note: When facing the front or rear of the memory box, the four sockets at the left are positioned in the opposite direction from the four sockets at the right. Be sure to reverse the DIMMs accordingly. Make sure the notches at the center of the DIMMs line up correctly with the tabs in the center of the sockets.
