IBM 440 manual SMP Expansion Ports with two SMP Expansion Modules installed

When a second SMP Expansion Module is installed in the x440, an additional three SMP Expansion Ports are made available on the rear of the chassis, giving a total of six. The SMP Expansion Module option includes two cables that are used to connect the modules together, as shown in Figure 3-5.

Figure 3-5 SMP Expansion Ports with two SMP Expansion Modules installed

Note: The two 10-inch scalability cables used to connect the two SMP Expansion Modules in a single x440 are included with the SMP Expansion module.

With single-x440 configurations, these ports are used to connect the two internal SMP Expansion Modules together. Only four ports are used (two cables). The other two ports are not connected.

When connecting two x440 nodes together to form a 16-way configuration, these ports are cabled together as shown in Figure 3-6 on page 76.
