Supported chassis and adapter cards
The switches are installed in switch bays in the rear of the Flex System chassis, as shown in Figure 2.
Switches are normally installed in pairs since ports on the I/O adapter cards installed in the compute nodes
are routed to two switch bays for redundancy and performance.
