1. Introduction to FGT_280D_POE-v6-build0131-FORTINET.out

This firmware package delivers FortiOS 6.4.15 for FortiGate 280D-POE series security appliances, released in Q1 2025 as a mission-critical update for distributed enterprise networks. Designed for environments requiring PoE-enabled network security with 802.3at/bt compliance, it resolves 3 high-severity vulnerabilities while optimizing power delivery management for IP cameras, VoIP systems, and wireless access points.

Exclusively compatible with FG-280D-POE hardware, the build0131 revision enhances integration with FortiSwitch 100/200 series through improved FortiLink protocols. The update maintains backward compatibility with configurations created in FortiOS 6.4.10+ but requires full hardware reset when downgrading from 7.x firmware branches.
