NP III and NP IV Memory Configurations
The NP III and NP IV have 64–256 MB of memory for protocol, file processing, and I/O cache memory.
Each NP has four or eight SIMMs of either 16 MB or 32 MB each. Refer to
for a list of memory
configurations supported by software Version 1.10.
Note:
NP SIMMs must be installed in groups of four of the same capacity.
