, two ports from the VIC 1340/1240 adapter are channeled to 2304 Fabric Extender A and two
are channeled to 2304 Fabric Extender B. The result is 20 Gb of bandwidth to each Fabric Extender.

, two ports from the VIC 1340 are connected to the 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 two additional ports to each of the port groups and thus create a native 40G
interface to each of the Fabric Extenders. Adapter slot 3 is empty. The result is 40 Gb of bandwidth to each
Fabric Extender.
