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, refer to the
section, “Getting Help,” on page 1-10 for details on how to contact Enterasys Networks.
Location of DIMM and DRAM SIMM Memory Modules
Figure B-5 and Figure B-6 show the locations of the DIMM and DRAM SIMM on each
main board. Although 4H4282-49 is shown in Figure B-5, the approximate location also
applies to the 4H4283-49 and 4H4284-49. Figure B-6 shows the approximate locations on
the 4H4203-72, and Figure B-7 shows the approximate locations on the 4H4202-72.
Caution: Because of the complexity of correctly replacing the large daughter board on
the 4H4202-72, there is no procedure in this manual for replacing the DIMM on a
4H4202-72. Contact Enterasys Networks support or nearest representative if you need to
replace the DIMM.
