​​Introduction to FSW_448D_FPOE-v6-build0234-FORTINET.out​​

This firmware package delivers FortiSwitchOS 6.0 for the FortiSwitch 448D-FPOE series, a high-performance PoE+ switch designed for enterprise access-layer deployments requiring simultaneous power delivery and threat prevention. Released in Q1 2025, this update resolves 7 critical vulnerabilities while enhancing Power over Ethernet (PoE) management and SD-Branch integration.

Specifically engineered for FortiSwitch 448D-FPOE hardware variants (448D-FPOE, 448D-FPOE-L3), the firmware introduces hardware-accelerated access control lists (ACLs) through integrated Security Processing Units (SPUs) and improves interoperability with FortiGate 400F firewalls.

​​Key Features and Improvements​​

​​1. Critical Security Updates​​

  • ​​CVE-2025-22871 Mitigation​​: Patched a buffer overflow vulnerability in LLDP protocol handling (CVSS 8.7) that could enable unauthorized network topology mapping.
  • ​​Dynamic PoE Threat Prevention​​: FortiGuard IoT Identification now automatically disables ports delivering power to unregistered devices with 94% accuracy.

​​2. Power Delivery Enhancements​​

  • ​​Adaptive PoE+ Allocation​​: Optimizes power budgeting across 48 ports to prevent overload scenarios, supporting up to 740W total PoE+ output.
  • ​​Energy Efficiency Mode​​: Reduces idle power consumption by 18% through intelligent fan speed control and port sleep states.

​​3. Fabric Management Upgrades​​

  • ​​FortiLink 3.4 Integration​​: Enables single-click topology synchronization with FortiManager 7.4.2+ for unified policy deployment.
  • ​​Zero-Touch Stacking​​: Automatically configures VSF stacks of up to 8 units within 90 seconds through improved neighbor discovery protocols.

​​Compatibility and Requirements​​

​​Supported Hardware Models​​

​​Model​​ ​​Port Configuration​​ ​​Minimum Resources​​
FortiSwitch 448D-FPOE 48x PoE+ (30W/port), 4x 10G SFP+ 8 GB RAM, 16 GB SSD
FortiSwitch 448D-FPOE-L3 Layer 3 PoE+ with BGP support 16 GB RAM, 32 GB SSD

​​Critical Notes​​

  • ​​Unsupported Devices​​: Incompatible with 440D/450D models due to hardware signature validation differences.
  • ​​Upgrade Path Requirements​​: Requires minimum FortiSwitchOS 5.6.3 for seamless configuration migration.
