1. Introduction to FSW_124F_FPOE-v7-build0102-FORTINET.out

This firmware update delivers critical security patches and operational enhancements for FortiSwitch 124F FPOE series managed switches, designed for enterprise networks requiring high-density Power over Ethernet (PoE) device management. Released in Q3 2025 under Fortinet’s Extended Security Maintenance program, build 0102 integrates with FortiOS 7.6.x security frameworks to provide:

  • ​​Industrial IoT Security​​: Enhanced device fingerprinting for 32 industrial control protocols
  • ​​Power Efficiency​​: Dynamic power budgeting for 90W PoE++ endpoints
  • ​​Zero Trust Integration​​: FortiLink extensions for FortiGate 800F/1000F controllers

Compatible exclusively with:

  • FortiSwitch 124F FPOE (FS-124F-FPOE) hardware
  • FortiSwitch Manager 7.6.3 or later

2. Key Features and Improvements

2.1 Security Enhancements
