SMP Expansion Port cabling for one server with two SMP Expansion
Modules: Complete the following steps to cable two SMP Expansion Modules in a
single server together, using the two 25.4 cm (10 in.) SMP Expansion cables, for up
to 8-way operation. In the illustration, the SMP Expansion Modules are numbered 0
and 1, from bottom to top. The SMP Expansion Ports are numbered 1 through 3,
left to right. If your server comes with two SMP Expansion Modules, the SMP
Expansion cables are included with the server. If you purchased a second SMP
Expansion Module, the cables are included with the option.

not connecting an RXE-100 enclosure, connect all remaining external cables to
the server; then, go to "Creating a scalable partition" on page 63 and follow the
instructions for creating a scalable partition.
Notes:
1. When multiple cables are connected between the SMP Expansion Module
ports, SMP data is interleaved between the cables for better performance.
2. The server will start and operate with one cable attached between the two
SMP Expansion Modules.
