You should be familiar with the memory configuration guidelines described in DIMM Population Rules before adding new DIMMs to increase a server's memory capacity.
Caution - You must disconnect the power cables from the system before performing this procedure.
Note - DIMM architectures must be identical (same capacity, same rank classification label). See DIMM Rank Classification Labels.
Do not dispose of the filler panel. You may want to reuse it if any DIMMs are removed at another time.
Caution - Ensure that the orientation is correct. The DIMM might be damaged if the orientation is reversed.

Note - If the DIMM does not easily seat into the connector, do not try to force it into position. Instead, check its orientation. If the orientation is not correct, forcing the DIMM into the connector is likely to damage the DIMM, or the connector, or both.
