In Figure 23, one port from the VIC 1340/1240 is channeled to 2204XP Fabric Extender A and one is
channeled to 2204XP Fabric Extender B. Adapter slot 2 is empty. The VIC 1380/1280 installed in adapter slot
3 channels two ports to each of the Fabric Extenders. The result is 30 Gb of bandwidth to each Fabric
Extender.
