Fabric gigabit switching within a chassis
You can use FortiSwitch-5003A fabric channel switching for communication
between the fabric backplane interfaces of FortiGate-5001A or 5005FA2 boards
installed in a FortiGate-5140 chassis.
Figure 9 shows a FortiGate-5140 chassis with a FortiSwitch-5003A board in
hub/switch slot 1, and FortiGate-5001A boards in 6 other slots. In this
configuration the FortiSwitch-5003A board provides 1-gigabit fabric backplane
switching for the FortiGate-5001A fabric1 interfaces. The FortiSwitch-5003A
boards operate as layer-2 switches and the FortiGate-5001A boards operate as
typical standalone FortiGate units.
