5 Enter the following command to switch the worker to load balance mode.
config system elbc
set mode forticontroller
end
The worker restarts in load balance mode and joins the cluster.
To verify that the worker has joined the cluster, from the FortiController-5103B
web-based manager and go to Load Balance > Status and verify that the worker
appears in the correct chassis slot.

6 Repeat these steps to add all workers to the cluster.
The worker in the lowest slot number becomes the primary unit.
7 Configure the cluster external management interface so that you can manage the
worker configuration. From the FortiController-5103B GUI go to Load Balance >
Config.
8 Edit the External Management IP/Netmask and change it to an IP address and
netmask for the network that the mgmt interfaces of the FortiController-5103B and the
FortiGate-5000 boards are connected to. The External Management IP/Netmask must
be on the same subnet as the FortiController-5103B management IP address.
You can now manage the workers by browsing to this External Management IP or by
logging into the FortiController-5103B GUI, going to Load Balance > Status and
selecting the Config Master icon beside the primary FortiGate-5000 unit, which is
always the top entry in the Worker Blade list.
