Adding/Replacing SIMM Modules

NOTE: A minimum of 4 MB of cache memory is required. The cache memory must be installed before the RAID controller is operational.

J22 is the bank 0 SIMM socket and J18 is the bank 1 SIMM socket. These sockets accept 72-pin SIMMs (� 36-type), available in sizes from 4 MB � 36 to 16 MB � 36. Use J22 if you are only using 1 SIMM socket. If you are using both sockets, make sure that the 2 SIMMs are the same type and capacity.

NOTE: If you use SIMMs with different capacities, the total cache memory is set to twice the capacity of the smaller of the 2 SIMMs.

CAUTION: The J2 cable connector on the battery backup module must be disconnected before you add or remove SIMM modules to or from the RAID controller card.

1. Shut down the operating system properly.
   Make sure that cache memory has been flushed. You must perform a system reset if operating under DOS. When the computer reboots, the RAID controller flushes cache memory.
2. Turn the computer power off, and disconnect the power cables from the computer.
3. Remove the computer cover.
4. Disconnect the battery cable connector from the J2 connector shown in the following figure.
   
5. Remove the RAID controller.
6. You can now add or remove SIMM modules from the RAID controller.
7. Reinstall the RAID controller in the computer.
8. Reconnect the battery cable connector to the J2 connector.
9. Replace the computer cover and turn the computer power on.
