Example of fccnt dump backbone screen display for a good connection:

Backbone for instance 1 is bound using local LUA 0x20 
remote LUA 0x10
         to interface TankTrsp
         E_Port interface is in passthrough mode
         Flow control mode 2
         connection is up - READY
         batching mtu is - 16000
         optical speed is 2 Gbps
         flow control is OFF

         Revision Level 16

Passthrough mode indicates that you have a good E_port connection.
