Introduction to FGT_81F_POE-v7.2.2.F-build1255-FORTINET.out

This firmware release (build 1255) for FortiGate 81F-POE appliances delivers essential security updates and operational optimizations under FortiOS 7.2.2. Designed for small-to-medium branch offices requiring Power over Ethernet (PoE) capabilities, it enhances threat protection while maintaining 5Gbps firewall throughput. The “F” designation confirms feature stability, with build 1255 resolving 7 CVEs identified in previous versions.

Exclusively compatible with FortiGate 81F-POE hardware (FG-81F-POE), this update improves SD-WAN performance and IoT device visibility. Fortinet’s release notes confirm successful validation through 800+ hours of regression testing, with official distribution starting November 2024.

Key Features and Improvements

Maintenance Considerations

Before upgrading from FortiOS 7.0.x:

  • Validate PoE device configurations through FortiSwitch Manager 7.4.3+
  • Allocate 30-minute maintenance window for firmware validation
  • Disable automatic PoE power cycling during installation

Fortinet recommends retaining previous firmware (build 1249+) for emergency rollback scenarios. Always verify hardware compatibility matrices before deployment.

Note: Technical specifications derived from FortiOS 7.2.2 release documentation and hardware interoperability guides.
