Workgroup System and Cluster Platform Express Overview and Hardware Installation Guide

If more than one interconnect is present, they are joined together in a federated configuration.
A typical cabling example of the federated cabling for two interconnects is shown in the following
table:
Uplink PortsDownlink Ports
21 – 249 – 12
In the cable labels, or cabling tables, you will see that both the origin and the destination for these
federated link cables is an ISR 9024 port, such as IB-SW1-P24 to IB-SW2-P24.
