Be sure to press the DIMM straight into the connector. Note If a gap exists between the DIMM and the retaining clips, the DIMM has not been properly installed. Open the retaining clips and remove the DIMM; then, reinsert the DIMM. c. Make sure that the retaining clips 2 are in the closed position. d. Repeat these steps for each DIMM that you install. 6. Reinstall the memory board: a. Insert the memory board into the guides and gently press the memory board into the connector. When you install the memory board in the server, be sure that it is correctly seated in the connector before you apply force to close the latches. b. Push the latches 1 until they close and lock in place. Attention To ensure proper EMC containment and cooling for the server, reinstall the memory-access panel before turning on the server. c.
