Supported chassis and adapters
The switches are installed in I/O module bays in the rear of the Flex System chassis as shown in the following
figure. Switches are normally installed in pairs because ports on the I/O adapter cards installed in the compute
nodes are routed to two I/O bays for redundancy and performance.
Figure 2. Location of the I/O bays in the Flex System chassis
The Flex System FC3171 8Gb SAN Switch and Pass-thru modules can be installed in I/O bays 1, 2, 3, and 4 of
the Flex System chassis. Up to four FC3171 modules supported in a chassis. A supported adapter card must
be installed in a corresponding slot of the compute node.
With compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC) the FC3171
modules 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 the slot that is routed to I/O
bays 1 and 2. However, when needed, the periscope connector can be replaced with an FC adapter card, in
which case integrated NIC will be disabled and FC modules can be used in bays 1 and 2.
The following table shows compatibility information for the FC3171 modules and Flex System chassis.

The 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 servers, such as the x240 with
two adapters, and full-wide servers, such as the x440 with four adapters.
