Failover in a standalone FortiGate-6000

A FortiGate-6000 will continue to operate even if an FPC fails. If a failure occurs, sessions being processed by that FPC also fail. All new sessions are load balanced to the remaining FPCs. Sessions that were being processed by the failed FPC are restarted and load balanced to the remaining FPCs.

An FPC can fail because of a hardware malfunction, a software problem, or a power supply failure. The FortiGate-6000 includes three hot-swappable power supplies in a 2+1 redundant configuration. At least two of the power supplies must be operating to provide power to the FortiGate-6000. If only one power supply is operating, some of the FPCs will be shut down. The FortiGate-6000 will continue to operate but with reduced performance because fewer FPCs are operating.

You can't replace an FPC that fails because of a hardware failure. Instead, you should RMA the FortiGate-6000.

To show the status of the FPCs, use the diagnose load-balance status command. In the command output, if Status Message is Running the FPC is operating normally. The following example shows the status of FPCs, for a FortiGate-6301F:
