Chapter 6. Multiple RS/6000 SPs and One SP Switch Router
In this configuration, two RS/6000 SP systems are connected to a single SP Switch Router. This enables both SPs to communicate deploying the SP Switch data transfer rate and/or to share other network resources. See Figure 65 for an overview.

6.1 RS/6000 SP Switch - RS/6000 SP Switch Connection
This scenario corresponds to Figure 65. It might be used to connect two RS/6000 SPs to exploit the SP Switch data transfer rate. Because of the switch cable length limit of 20m, this scenario is only applicable when both SPs have a maximum distance of 40m. In all other cases you will need two routers and a corresponding high speed connection (refer to Chapter 7, “Multiple RS/6000 SPs and Multiple GRFs” on page 209).
Configuration assumptions:
•Both SP Switch Router Adapter cards have been installed according to Section 3.7,
Note: When configuring the second SP Switch Router Adapter card, ensure that both Control Workstations are defined as SNMP managers in
