, two ports from the VIC 1340 are connected to 2304 Fabric Extender A and two are connected
to 2304 Fabric Extender B. The Port Expander Card installed in adapter slot 2 acts as a pass-through device
to provide additional ports to each of the port groups and thus create a native 40G interface to each of the
Fabric Extenders. In addition, the VIC 1380 connects four ports to each Fabric Extender. The result is 80 Gb
of bandwidth to each Fabric Extender.

, four ports from the VIC 1280 are channeled to 2304 Fabric Extender A and four are channeled
to 2304 Fabric Extender B. The VIC 1240 slot is empty and adapter slot 2 is empty. The result is 40 Gb of
bandwidth to each Fabric Extender.
