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.
