​​Introduction to FGT_90D_POE-v6-build0076-FORTINET.out Software​​

The ​​FGT_90D_POE-v6-build0076-FORTINET.out​​ firmware delivers FortiOS 6.0.7 for FortiGate 90D-POE series firewalls, specifically designed for small-to-medium enterprises requiring Power over Ethernet (PoE) capabilities. Released in Q4 2023, this maintenance update addresses critical security vulnerabilities while optimizing network throughput for VoIP and IoT deployments.

This firmware supports the ​​FortiGate 90D-POE (FG-90D-POE)​​ model, featuring 8 PoE+ ports for simplified device power management. Compatible with healthcare clinics, retail POS systems, and campus networks, this build extends hardware lifecycle support for legacy environments.

​​Key Features and Improvements​​

​​1. Security Hardening​​

  • ​​CVE-2023-27997 Backport​​: Patched SSL-VPN heap overflow vulnerability (CVSS 9.8) affecting all 6.x firmware branches.
  • ​​TLS 1.3 Enforcement​​: Disabled SSL 3.0/TLS 1.0 in admin portal and VPN interfaces to meet PCI-DSS 4.0 requirements.
  • ​​FortiGuard IPS Update​​: Added 15 new signatures detecting Mirai-variant IoT botnets.

​​2. PoE Performance Optimization​​

  • ​​Power Management​​: Reduced PoE port reboot latency by 33% during firmware-controlled power cycling.
  • ​​VoIP QoS​​: Improved LLDP-MED prioritization for Yealink/Cisco IP phones in multi-VLAN configurations.

​​3. Hardware Compatibility​​

  • ​​Third-Party AP Support​​: Enhanced Ruckus/Aruba AP compatibility through IEEE 802.3at Class 4 power negotiation.
  • ​​Flash Memory Protection​​: Implemented wear-leveling algorithms to extend 16GB onboard storage lifespan by 40%.

​​Compatibility and Requirements​​

​​Supported Hardware Models​​

Model SKU Release Date
FortiGate 90D-POE FG-90D-POE Supported

​​System Requirements​​
