TITLE:       Backplane Flex Channels for VNBus
                ---------------------------------

   PROBLEM:     How many backplane flex channels does the VNBus use?

   SOLUTION:    The VNBus uses three backplane flex channels. When using
                VNBus along with Ethernet and FDDI connections on the
                backplane, the flex channels can easily be used up. Plan before
                implementing the backplane Flex channels. Always PLAN any
                switch parameter before configuring.
