Supported chassis and adapter cards
The switches are installed in switch bays in the rear of the Flex System Enterprise Chassis, as shown in
the following figure. Switches are normally installed in pairs because I/O adapter cards installed in the
compute nodes route to two switch bays for redundancy and performance.
Figure 2. Location of the switch bays in the Flex System Enterprise Chassis
The midplane connections between the adapters installed in the compute nodes to the switch bays in the
chassis are shown diagrammatically in the following figure. The figure shows both half-wide compute
nodes, such as the x240 with two adapters, and full-wide compute nodes, such as the p460 with four
adapters.
