Figure 5 -3: Insert the DIMM Module
Step 5. Reinstall the controller module. After the DIMM module has been
properly installed, the controller module must be reinstalled. To do
this, align the controller module with the controller module bay. Then
gently push the controller module in the controller bay. Carefully
push the controller until you feel the contact when the board edge
connectors are mated to the backplane. Do not use force. If unusual
contact resistance is felt, try it again. Next secure the controller
module into the subsystem by fastening the hand screws on the sides.
NOTE:
When replacing a DIMM, the whole subsystem needs to be powered down.
Therefore, when replacing a DIMM, you should carefully select the time when the
replacement will be made in order to minimize the overall disruption to service.
