FortiSwitch-5003A and 5003 Fabric and Base Backplane Communications Guide
70 01-30000-85717-20081205
Base backplane HA configurations FortiGate-5140 and 5050 base backplane communication
• Separate multiple sensitive or high volume communications, such as HA
communications for multiple clusters. For example, if you have two busy
FortiGate-5005FA2 clusters, you might configure one cluster to use base1 for
HA heartbeat traffic and the other to use base2.
Figure 24: FortiGate-5050 HA cluster with two available base backplane heartbeat
interfaces (through FortiSwitch-5003A boards in hub/switch slots 1 and 2)
Figure 25: FortiGate-5050 inter-chassis HA cluster using both base backplane
heartbeat interfaces (through FortiSwitch-5003A boards in hub/switch
slots 1 and 2)
Note: More than one cluster can use the same base backplane channel for HA
communication. To separate HA communications of multiple clusters using the same
channel, configure a different HA Group Name and Password for each cluster.
