The wiring for two enclosures can be derived from the three enclosure wiring tables by omitting the wiring for Enclosure 3. The connection to Port 4 on the fourth external InfiniBand switch (IB-SW4) depends on whether the configuration includes an external control node connected to the InfiniBand fabric or not. If there is a control node connected to the InfiniBand fabric, the control node's HCA is connected to that port. Otherwise, Port 4 on the fourth InfiniBand switch is connected to Port 8 on the InfiniBand switch installed in Interconnect Module Bay 5/6 installed in Enclosure 1.
