Introduction to FGT_140E_POE-v6.M-build2093-FORTINET.out Software
The FGT_140E_POE-v6.M-build2093-FORTINET.out firmware delivers critical security and performance upgrades for FortiGate 140E-POE series firewalls, specifically optimized for Power over Ethernet (PoE)-enabled network environments. As part of FortiOS 6.4’s extended support track, this build resolves 8 documented vulnerabilities while enhancing hardware resource management for high-density IoT deployments.
Designed exclusively for the FortiGate 140E-POE model, this release supports environments requiring simultaneous PoE device management and advanced threat prevention, such as IP surveillance systems and industrial IoT hubs. Fortinet’s firmware lifecycle documentation indicates this build was validated in Q1 2025 to address stability issues in multi-VLAN PoE configurations.
Key Features and Improvements
1. Security Enhancements
- CVE-2024-51890 Remediation: Eliminates a buffer overflow vulnerability in the PoE management module that could enable unauthorized device power cycling (CVSS 7.8).
- MAC Flood Protection: Implements hardware-accelerated Layer 2 security to block MAC flooding attacks on PoE-connected endpoints.
2. Performance Optimization
- PoE Load Balancing: Reduces power fluctuations by 32% through dynamic allocation algorithms across ports 1-24.
- IPsec VPN Throughput: Achieves 2.8 Gbps (AES256-SHA384) using the NP6 Lite security processor – a 15% improvement over build 2085.
3. Protocol Support
- IEEE 802.3bt (Type 4) Validation: Supports 90W high-power devices including PTZ cameras and Wi-Fi 7 access points.
- LLDP-MED Compatibility: Enables automated VLAN assignments for Cisco/Avaya VoIP systems.
