The system includes two processor boards capable of
supporting up to four Pentium Pro processors (two per
board). Each processor board has two processor sockets.
The board contains DC to DC converters for power to
each processor (Figure 2-4, A and B). The Pentium Pro
processors plug into a Zero Insertion Force (ZIF)
sockets on this board (Figure 2-4, C and D). An optional
second Pentium Pro processor enhances performance
and enables symmetric multiprocessing (SMP). Both
processors access the same memory and I/O space and
tasks can run on either CPU if your operating system
(OS) supports SMP.
The memory board contains sixteen 168-pin DIMM
sockets (Figure 2-5). The minimum system
configuration includes 64 MB (using two 32 MB
DIMMs) of system memory. 16 DIMM sockets allow for
system memory expansion to 4 GB (using sixteen 256
MB DIMMs). ECC generation/checking is provided for
detection and correction of memory errors.
Note: Only use DIMMs approved for use in this server
system. Call your customer service representative for
information.
