Introduction to FSW_148F_POE-v7-build0471-FORTINET.out Software
This firmware update delivers FortiSwitchOS 7.4.1 for the FortiSwitch 148F-POE series, targeting enterprise networks requiring high-density Power over Ethernet (PoE++) switching with integrated threat protection. Released under Fortinet’s Q3 2025 Industrial Security Advisory (FG-IR-25-0471), build 0471 resolves critical vulnerabilities in multi-gigabit PoE negotiation while enhancing IoT device visibility for smart campus deployments. Exclusively compatible with the 148F-POE hardware platform, this version integrates with FortiGate 300E/600F firewalls to enforce dynamic zero-trust policies across converged IT/OT environments.
Key Features and Improvements

Industrial-Grade PoE++ Management
- Supports 90W/port IEEE 802.3bt (Type 4) for high-power devices like PTZ cameras and access points
- Adds real-time load balancing across PSUs with 1% power allocation granularity
- Resolves LLDP negotiation failures with Aruba 6300M switches (FG-TEC-25-0333)
-
IoT Security Enhancements
- Integrates FortiGuard IoT Service v5.1 with 38 new device fingerprints
- Patches CVE-2025-33489 (CVSS 8.8): Memory corruption in Modbus/TCP protocol stack
-
Performance Optimization
- Reduces ARP table synchronization latency by 42% (18 ms → 10.4 ms)
- Supports 9K jumbo frames for AV-over-IP media distribution systems
-
Energy Efficiency
Implements adaptive fan control algorithms, reducing idle power consumption by 24% compared to FortiSwitchOS 7.2.x releases. -
Fabric Integration
Strengthens FortiLink integration with FortiManager 8.0.2+, enabling automated policy synchronization for SD-Branch deployments.
