configuration
By default, FortiGate-5001SX modules use port9 and port10 (the base backplane
interfaces) as heartbeat interfaces. Because base backplane interfaces cannot be
used in inter-chassis configurations, if you want to form an inter-chassis HA
cluster, these default heartbeat interfaces should be disabled. In the above
example, the front panel interfaces port7 and port8 are enabled as heartbeat
interfaces, and port9 and port10 are disabled.
