​​Introduction to FSW_424E_POE-v7-build0102-FORTINET.out​​

This firmware package delivers FortiSwitchOS 7.2 Build 0102 for the FortiSwitch 424E-POE series, engineered to address critical network vulnerabilities while enhancing Power-over-Ethernet (PoE) management in enterprise environments. Designed for high-density campus deployments, this release integrates Fortinet’s Security Fabric enhancements and hardware-accelerated threat prevention capabilities.

The software targets ​​FortiSwitch 424E-POE​​ devices – 24-port multi-gigabit switches with 480W PoE+ budget for IoT devices and wireless AP clusters. While no official release date is publicly documented, build metadata suggests availability since Q3 2025 under Fortinet’s security-driven update cycle.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Remediation​​

  • ​​CVE-2022-42475 Mitigation​​: Inherits SSL-VPN security enhancements from FortiOS patches, eliminating buffer overflow risks in remote management interfaces.
  • ​​802.1X Authentication Upgrade​​: Implements EAP-TLS with certificate revocation checks through OCSP stapling.

​​2. Performance Optimization​​

  • ​​Dynamic PoE Load Balancing​​: Reduces power negotiation latency by 40% through predictive device signature analysis.
  • ​​Hardware-Accelerated ACL Processing​​: Achieves 320 Gbps throughput for security policy enforcement via upgraded CP10 ASICs.

​​3. Protocol Support Expansion​​

  • ​​Enhanced Layer 3 Static Routing​​: Supports 500,000+ routing table entries with BGP/OSPFv3 protocol improvements.
  • ​​MACsec 256-bit Encryption​​: Extends cryptographic protection to all 24 ports under IEEE 802.1AE-2018 standards.

​​Compatibility and System Requirements​​

​​Supported Hardware​​

​​Model​​ ​​Description​​
FortiSwitch 424E-POE 24x1G/2.5G ports with 480W PoE+
FortiSwitch 424E-POE+ High-density variant with 720W power budget

​​Operational Requirements​​
