Installing the DIMM
About this task
Complete the following steps to install the DIMM in the controller:
Procedure
1. Open the retaining clip on each end of the DIMM connector.
2. Touch the static-protective package that contains the DIMM to any unpainted metal surface on the
storage subsystem. Then, remove the DIMM from the package.
3. Turn the DIMM so that the DIMM keys align correctly with the slot.
4. Match the angle of the DIMM with the angle of the connector.
5. Firmly press the DIMM into the connector. The retaining clips snap into the locked position when the
DIMM is firmly seated in the connector. If there is a gap between the DIMM and the retaining clips,
the DIMM has not been correctly inserted; open the retaining clips, remove the DIMM, and then
reinsert it.
6. Install the cover (see “Removing and installing a cover” on page 91).
7. Insert the controller into the chassis.
a. Make sure that the release levers on the controller are in the open position.
b. Slide the controller into the bay until it stops.
c. Push the release levers to the closed position.
Attention: After you remove a controller, wait 90 seconds before you reseat or replace the controller.
Failure to do so might cause unpredictable results.
