Introduction to FGT_240D_POE-v6-build0484-FORTINET.out
This firmware package delivers critical infrastructure protection updates for Fortinet’s enterprise-grade FortiGate 240D-POE next-generation firewall, specifically designed for high-density PoE network environments. Released under Fortinet’s Q2 2025 security maintenance cycle, build 0484 combines essential vulnerability remediation with hardware performance optimizations for mission-critical deployments.
Compatible exclusively with FortiGate 240D-POE hardware (FG-240D-POE series), this update maintains backward compatibility with FortiOS 6.4.x configurations while implementing security backports from newer firmware branches. The “v6-build0484” identifier confirms integration with FortiOS 6.4.15 architecture, certified for deployment in PCI-DSS compliant networks.
