Introduction to FSW_148E-v7-build0102-FORTINET.out

This firmware package delivers FortiOS 7.0.1 for FortiSwitch 148E series, designed for enterprise campus networks requiring 48-port 25Gbps switching with PoE+ capabilities. Officially released on April 5, 2025, build 0102 addresses 9 critical vulnerabilities from FortiOS 7.0.0 while introducing enhanced automation features for software-defined access deployments.

Certified for education and healthcare verticals, this update supports hardware models 148E/148E-POE/148E-FX with backward compatibility for configurations from FortiOS 6.4.x through policy migration tools. The firmware enables <18μs latency for real-time collaboration applications in cut-through switching mode.
