Introduction to FSR_112D_POE-v6-build0234-FORTINET.out Software

This firmware package delivers FortiOS 6.0.2 for FortiSwitch 112D-POE series, engineered for enterprise-grade Layer 3 switching with 48-port PoE++ support. Released on March 10, 2025, build 0234 resolves 9 critical vulnerabilities identified in FortiOS 6.0.1 while introducing enhanced network segmentation capabilities.

Designed for healthcare and education deployments requiring 240W PoE budget per rack unit, this update maintains backward compatibility with configurations from FortiOS 5.6.x through automated policy migration tools. The “POE” designation confirms optimized power management for IP cameras, VoIP phones, and IoT devices.
