IBM Flex System devices

(IBM Flex System® devices only) For IBM Flex System devices, ports are numbered in bay, offset, and mezzanine order. Flex System devices offer four offsets per bay, 2 mezzanines per offset, and 8 physical ports (16 virtual mezzanine). The mapping of ports to the devices on the compute node is not limited by fabric type.

The following table defines the mapping of the IFM ports to the switch numbering on the IBM Flex System chassis.
