Base backplane communications and HA between FortiGate-5020 chassis
This chapter describes:
•FortiGate-5020 base backplane interfaces
•FortiGate HA between two FortiGate-5020 chassis
FortiGate-5020 base backplane interfaces
For the FortiGate-5020 chassis, you can use the FortiGate-5000 module base backplane interfaces for HA heartbeat communication and data communication between the two FortiGate modules installed in the same chassis. No changes to the chassis configuration or additions to the chassis hardware are required. The FortiGate-5020 chassis does not allow communication between different base backplane channels or directly from the backplane to external networks. So the base backplane interfaces can only be used for HA and data communication between the FortiGate modules in the chassis, and only inside the same base backplane channel.
Note: VLAN communication over the base backplane interfaces is available for FortiGate-5000 modules installed in a FortiGate-5020 chassis. The FortiSwitch-5003 does not support VLAN-tagged packets so VLAN communication is not available over the FortiGate-5050 and FortiGate-5140 chassis base backplane interfaces.
For example, if you have two FortiGate-5001SX modules installed in a FortiGate-5020 chassis, you can enable the base backplane interfaces for data communication and then you can communicate data from port9 on one FortiGate-5001SX module to port9 of the other module. You can also communicate data between port10 on one FortiGate-5001SX module and port10 on the other FortiGate-5001SX module. However, you cannot communicate data between port9 on one FortiGate-5001SX module and port10 on the other FortiGate-5001SX module.
Data communication between different FortiGate-5000 modules is supported. So, for example, if you install a FortiGate-5001FA2 and a FortiGate-5001SX module in the same FortiGate-5020 chassis, you can communicate between port9 of the FortiGate-5001FA2 module and port9 of the FortiGate-5001SX module. You can also communicate between port10 of the FortiGate-5001FA2 and port10 on the FortiGate-5001SX module.
