Introduction to FSW_124E_FPOE-v6-build0234-FORTINET.out

This firmware update (v6-build0234) delivers critical security hardening and operational optimizations for FortiSwitch 124E-FPOE series, Fortinet’s Power-over-Ethernet (PoE) enabled switches designed for enterprise campus networks. Released on May 12, 2025, it addresses 4 CVEs identified during Q1 2025 security audits while enhancing PoE management capabilities for IoT device deployments.

Compatible with 124E-FPOE hardware variants featuring 24x PoE+ ports, this build introduces granular power budgeting controls and improves stacking stability for high-density environments. The update aligns with FortiOS 7.6.x security fabric integrations, enabling centralized policy enforcement across hybrid networks.
