A.1.4.1 NVSIMM
A-6
The 8 Mbyte SIMMs of either vendor can be mixed in a group. Similarly, both
vendor's 32 Mbyte SIMMs can be mixed in a group. However, all SIMMs of a
group must be of identical capacity (all 8 Mbyte; all 32 Mbyte; or all NVSIMM
within a group). Additionally, 8- and 32 Mbyte SIMMs can be used on the same
board, provided they do not reside within the same group.
Figure A-4 SIMM Locations on the System Board
Before installing NVSIMMs you must first activate the battery to insure data
retention.
To activate the battery:
1. Locate the jumper on the right side of the NVSIMM.
See Figure A-5.
