1. Introduction to FSW_424E_FPOE-v7-build0102-FORTINET.out

This firmware package delivers FortiSwitch OS 7.0.102 for the FortiSwitch 424E-FPOE series, a critical update released under Fortinet’s Q2 2025 network infrastructure enhancement initiative. Designed for high-density Power over Ethernet (PoE) environments, this build addresses 9 CVEs while optimizing Layer 2/3 switching performance for enterprise campus networks and IoT deployments.

Key applications include:

  • 802.3bt (90W) device management with dynamic power allocation
  • FIPS 140-3 Level 2 compliant network operations
  • Real-time threat prevention through FortiGuard integration

Certified exclusively for FortiSwitch 424E-FPOE hardware, the update requires existing FortiSwitch OS 7.0.x installations with 8GB RAM and 64GB flash storage.

2. Technical Enhancements and Security Updates
