The connections between the 4-port FC adapters that are installed in the compute nodes and the switch
bays in the chassis are shown in Figure 4.

The IBM Flex System FC5022 16Gb SAN Scalable Switches can be installed in bays 1, 2, 3, and 4 of the
Enterprise chassis. A supported adapter card must be installed in a corresponding slot of the compute
node (slot A1 when switches are installed in bays 1 and 2 or slot A2 when switches are in bays 3 and 4).
With compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC) these
switches can only be installed in bays 3 and 4 because integrated NICs ports are routed to bays 1 and 2
with a specialized periscope connector and the FC adapter card cannot be installed in slot A1. When
needed, however, the periscope connector can be replaced with an FC adapter card, in which case the
integrated NIC will be disabled and FC switches can be used in bays 1 and 2.
