4. Remove the DIMM from the connector.
a. Wait 60 seconds before you proceed, to allow any residual charge to drain
from the controller.
b. Open the retaining clip on each end of the DIMM connector.
c. Lift the DIMM out of the connector.
5. If the DIMM is functional (not failed), place the DIMM in a static-protective
package until you are ready to install it.
6. If you are removing the DIMM as part of replacing a controller, return to step
11b on page 68. Otherwise, continue to “Installing the DIMM” to install the new
or replacement DIMM.
Installing the DIMM
With the controller removed from the chassis and the battery removed from the
controller, complete the following steps to install the DIMM in the controller:
1. Make sure that at least 60 seconds has elapsed since you removed the battery
from the controller.
2. Open the retaining clip on each end of the DIMM connector.
3. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the DS3300. Then, remove the DIMM from the package.
4. Turn the DIMM so that the DIMM keys align correctly with the slot.
5. Match the angle of the DIMM with the angle of the connector.
6. 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.
