1. Introduction to FGT_280D_POE-v6-build0365-FORTINET.out
This firmware package delivers FortiOS 6.4.15 for FortiGate 280D-POE series security appliances, released in Q2 2025 as a critical infrastructure update. Designed for enterprise networks requiring IEEE 802.3bt PoE++ compliance, it resolves 3 high-severity vulnerabilities while optimizing power delivery management for IoT devices and wireless access points. The build0365 revision specifically enhances integration with FortiSwitch 148E-POE devices through improved FortiLink protocols, addressing packet loss issues observed in high-density deployments.
Exclusively compatible with FG-280D-POE hardware, this update maintains backward compatibility with configurations created in FortiOS 6.4.12+ but requires full system reboot when downgrading from 7.x firmware branches. The release coincides with updated NIST 800-193 firmware resilience guidelines, ensuring compliance for government and healthcare networks.
