Introduction to FSW_448E-v7-build0102-FORTINET.out

This firmware update delivers FortiOS 7.0.1 for FortiSwitch 448E series, engineered for hyperscale data center deployments requiring 48-port 100Gbps switching with advanced fabric automation. Released on May 10, 2025, build 0102 resolves 14 critical vulnerabilities from FortiOS 7.0.0 while introducing adaptive traffic engineering for AI/ML workload optimization.

Certified for cloud service providers and financial trading platforms, this version supports hardware variants 448E/448E-POE/448E-XL with backward compatibility for configurations from FortiOS 6.4.x through automated policy migration. The firmware achieves <10μs latency for high-frequency trading applications when using cut-through switching mode.
