Active passive HA configuration where the primary FortiController-5103B board is 
processing traffic and the subordinate FortiController-5103B board is in hot standby 
mode. Sessions are synchronized between the FortiController-5103B boards and if 
the primary fails all sessions are taken up by the subordinate with minimal disruption.
Dual FortiController mode where both FortiController-5103B boards are processing 
traffic and load balancing it to all the workers. The FortiController-5103B board in 
slot1 is the primary FortiController-5103B board for management purposes, but the 
F1 to F8 ports on both FortiController-5103B boards are active. The workers show 16 
interfaces named fctrl1/f1 to fctrl1/f8 and fctrl2/f1 to fctrl2/f8. 
Adding a second Chassis
You can also add a second chassis for chassis failover. Chassis failover is supported for 
active-passive HA and dual mode configurations. A dual-chassis active-passive HA 
configuration can involved one or two FortiController-5103B boards in each chassis.
