1. Memory RDIMMs must be installed in sequence from RDIMM connector 1
through connector 4. RDIMM size is not relevant.
This table does not represent all possible memory configurations. Memory modules may vary in price
per MB. Selection of smaller RDIMMs may provide a more cost-effective alternative to using larger
RDIMMs.
1. Network operating systems may limit the maximum amount of addressable memory. See operating
system specifications for further information. Optimum performance occurs with 1GB total memory.
2. Requires removal of standard memory.
