FortiGate-400 Administration Guide
Inserting an HA cluster into your network temporarily interrupts communications on
the network because new physical connections are being made to route traffic through
the cluster. Also, starting the cluster interrupts network traffic until the individual
FortiGate units in the cluster are functioning and the cluster completes negotiation.
Cluster negotiation normally takes just a few seconds. During system startup and
negotiation all network traffic is dropped.
1 Connect the cluster units.
• Connect port 1 of each FortiGate unit to a switch or hub connected to your internal
network.
• Connect port 2 of each FortiGate unit to a switch or hub connected to your external
network.
• Optionally connect port 3 of each FortiGate unit to a switch or hub connected to
another network.
• Connect the 4/HA interfaces of the FortiGate units to another switch or hub.
