The FortiGate-5140 chassis and the FortiGate-5050 chassis have two base
backplane Ethernet channels. Available connections to these channels vary by
hub/switch slot number.
• Hub/switch slot 1 can connect to the first base backplane channel, and thereby
all other chassis slots, except hub/switch slot 2.
• Hub/switch Slot 2 can connect the to the second base backplane channel, and
thereby all other chassis other slots, except hub/switch slot 1.
• Other slots can connect to either or both channels, but only directly reach
hub/switch slot 1 or hub/switch slot 2. Connections to other slots through the
base backplane channels must pass through hub/switch slot 1 or hub/switch
slot 2.
Note: For more information on chassis architecture, see ATCA (Advanced Telecom
Computing Architecture) specifications.
Because of the base backplane dual star topology, connecting to or through the
base backplane requires FortiSwitch-5003A or 5003 boards installed in
hub/switch slot 1, hub/switch slot 2, or both.
FortiSwitch-5003A boards switch base backplane traffic between boards in other
slots. FortiSwitch-5003A front panel base interfaces can also connect the chassis
base backplane to external entities, such as a management computer, the
network, or the base backplane of another chassis.
FortiSwitch-5003 boards switch base backplane traffic between boards in other
slots. FortiSwitch-5003 front panel ZRE interfaces can also connect the chassis
base backplane to external entities, such as a management computer, the
network, or the base backplane of another chassis.
Note: The FortiSwitch-5003A board and the FortiSwitch-5003 board provide the same
base backplane switching capabilities. All of the configurations described in this section
could be accomplished with either of these boards. The only exception is that the
FortiSwitch-5003A board supports VLAN-tagged traffic on the base channel while the
FortiSwitch-5003 board does not.
