a variety of I/O architectures.
The switches are installed in switch bays in the rear of the IBM Flex System Enterprise Chassis as shown
in the following figure. Switches are normally installed in pairs (bays 1 & 2, and bays 3 & 4), because I/O
adapter cards installed in the compute nodes route to two switch bays for performance and redundancy.
