Memory Locations and Replacement Procedures Memory Locations and Replacement Procedures In the event that the Dual in Line Memory Module (DIMM) or DRAM Single In‐line Memory Module (SIMM) (FLASH memory) needs to be replaced, the following sections describe how to access, locate and replace these memory modules. If you have questions concerning the replacement of either memory module, contact Enterasys Networks.
Memory Locations and Replacement Procedures DIMM Replacement Procedure If the DIMM is defective and must be replaced, the following sections explain how to remove and install the DIMM. If you have questions concerning the replacement of the DIMM, contact Enterasys Networks. Removing the DIMM To remove the existing DIMM, proceed as follows: 1. Follow steps 1 through 3 as instructed on (page B‐7). 2. Locate the DIMM connector on the motherboard as shown in Figure B‐2. 3.
Memory Locations and Replacement Procedures Installing the DIMM To install a DIMM, refer to Figure B‐4 and proceed as follows: 1. Insert the DIMM down between the connector fingers. 2. Pivot the DIMM downward so the tabs on the connector arms align with the two DIMM alignment notches. With the two connector arms spread outward, push the DIMM down between the connector arms. Then release the two connector arms to lock the DIMM into place.
Memory Locations and Replacement Procedures Removing the DRAM SIMM 1. Place the 2G4072‐52 on a clean, static‐free surface. 2. Remove the 12 screws securing the chassis cover, as shown in Figure B‐5.
Memory Locations and Replacement Procedures 3. Push the connector arms away from the memory module to release the DRAM SIMM from the connector, as shown in Figure B‐6. Note: The ejector arms on this connector are not spring loaded, so they will remain in the open position until manually closed.
