Base backplane HA configurations FortiGate-5140 and 5050 base backplane communication
Figure 29: FortiGate-5050 HA cluster with one available base backplane heartbeat
interface (through a FortiSwitch-5003A board in slot 2)

interface (through a FortiSwitch-5003A board in slot 1)
Note: Using a single FortiSwitch board for HA heartbeat communication introduces a single
point of failure. If this FortiSwitch board fails or is removed, HA heartbeat communication
will be interrupted. For enhanced reliability, you can add a second FortiSwitch board. You
can also improve reliability by connecting and configuring one or more other heartbeat
interfaces.
