1. Introduction to FGT_140E_POE-v6-build1803-FORTINET.out

This firmware release (build 1803) provides critical security patches and operational optimizations for FortiGate 140E-POE series appliances deployed in mid-sized enterprise networks. As part of FortiOS 6.4 branch maintenance updates, it resolves 17 CVEs identified in previous versions while enhancing NP6Lite ASIC utilization for 5Gbps firewall throughput environments.

Designed specifically for FG-140E-POE hardware platforms, the update supports Power over Ethernet (PoE) configurations and 64GB SSD storage architecture. Released through Fortinet’s April 2025 security bulletin cycle, it requires 16GB free storage space for installation validation and maintains backward compatibility with FortiOS 6.4.7+ configurations.
