Introduction to FSW_124E_FPOE-v6-build0512-FORTINET.out

This firmware update delivers FortiOS 6.0.5 for FortiSwitch 124E-FPOE series, designed for enterprise edge networks requiring 24-port 60W PoE+ capabilities. Released on March 15, 2025, build 0512 addresses 7 critical vulnerabilities from FortiOS 6.0.4 while introducing enhanced traffic segmentation features for IoT environments.

Engineered for retail and hospitality deployments, this version supports hardware models 124E-FPOE/124E-FPOE-R2 with backward compatibility for configurations from FortiOS 5.6.x via automated policy migration. The “FPOE” designation confirms compliance with IEEE 802.3at Power over Ethernet Plus standards.
