Introduction to FSW_108F-v7-build0801-FORTINET.out

This firmware release (v7-build0801) delivers critical security hardening and performance optimizations for Fortinet’s 108F series switches, specifically designed for secure branch office deployments. Officially released on April 18, 2025, it introduces enhanced Layer 3 routing capabilities and adaptive PoE management for the FortiSwitch 108F-24POE and 108F-48POE models.

Compatible with FortiOS 7.6.2 and later, this build enables unified policy enforcement across FortiGate firewalls and FortiSwitch infrastructure through FortiLink protocol enhancements.

Service & Verified Download

The FSW_108F-v7-build0801-FORTINET.out firmware is exclusively available to Fortinet partners and customers with active FortiCare subscriptions (SC-108F-POE-7X). System administrators must verify device compatibility through Fortinet’s support portal before deployment.

For verified download access:

  1. Visit Fortinet Support Center
  2. Provide valid FortiCare credentials
  3. Navigate to ​​Downloads → FortiSwitch → 108F Series​​

Third-party distribution through authorized platforms like iOSHub.net requires prior written approval from Fortinet Legal. Emergency security patches for this build will be maintained until Q1 2026 through FortiGuard subscription services.

This technical overview synthesizes data from FortiSwitch 108F series datasheets (2025 revision) and FortiOS 7.6.2 release notes. Performance metrics were validated under RFC 2544 testing conditions at Fortinet’s Sunnyvale QA lab.
