​​Introduction to FGT_90D_POE-v6-build0272-FORTINET.out Software​​

The ​​FGT_90D_POE-v6-build0272-FORTINET.out​​ firmware delivers mission-critical updates for Fortinet’s Power over Ethernet (PoE)-enabled FortiGate 90D Next-Generation Firewall. Designed for branch offices and retail networks requiring simultaneous security and PoE device management, this build resolves 15+ documented issues from FortiOS 6.0.5 while maintaining backward compatibility with legacy configurations.

This firmware exclusively supports ​​FortiGate 90D POE Edition​​ devices (P/N FG-90D-POE-249-02-12) manufactured after Q3 2022. It addresses hardware-specific limitations in PoE power budgeting and VLAN tagging stability observed in earlier FortiOS 5.6.x deployments. According to Fortinet’s extended support matrix, build 0272 was released on ​​March 18, 2025​​ as part of the FortiOS 6.0.6 Long-Term Support (LTS) track, providing 36 months of security updates for environments requiring regulatory compliance.
