Gaining Access to Memory Modules

2.Remove the two screws fastening the NEM to the DFE module front panel and remove the standoff fastening the NEM to the main board. Save the two screws and standoff for later use to reinstall the NEM.

3.Lift and remove the NEM off the two main PC board connectors. Now you have access to the DRAM SIMM. To replace the DRAM SIMM, proceed to “Removing the DRAM SIMM”.

Removing the DRAM SIMM

To remove the DRAM SIMM, refer to Figure B‐5 and proceed as follows.

1.Refer to Figure B‐5. Push the connector arms away from the DRAM SIMM to release it from the connector.

Note: The ejector arms on this connector are not spring-loaded, so they will remain in the open position until manually closed.

2.Remove the DRAM SIMM from the connector.
