2 Power on all the FortiGate units in the cluster.
As the units start, they negotiate to choose the primary cluster unit and the
subordinate units. This negotiation occurs with no user intervention and normally just
takes a few seconds.
You can now configure the cluster as if it is a single FortiGate unit.
To add a new unit to a functioning cluster
1 Configure the new FortiGate unit for HA operation with the same HA configuration as
the other units in the cluster.
2 If the cluster is running in Transparent mode, change the operating mode of the new
FortiGate unit to Transparent mode.
3 Connect the new FortiGate unit to the cluster.
4 Power on the new FortiGate unit.
When the unit starts it negotiates to join the cluster. After it joins the cluster, the cluster
synchronizes the new unit configuration with the configuration of the primary unit.
