Supported chassis and adapters
The EN4093 switches are installed in I/O module bays in the rear of the Flex System chassis, as shown in the
following figure. I/O modules are normally installed in pairs because ports on the I/O adapters that are installed in
the compute nodes are routed to two I/O module bays for redundancy and performance.
