Introduction to FSW_148F_POE-v7-build0801-FORTINET.out

This firmware release (build 0801) provides critical updates for Fortinet’s ​​FortiSwitch 148F-POE​​ series – a 48-port managed switch optimized for high-density Power-over-Ethernet deployments in enterprise campuses and IoT environments. Officially released on March 10, 2025, this v7.4.2 update focuses on SD-Branch network hardening and energy efficiency compliance with Energy Star 4.0 standards.

Designed for environments requiring:

  • 90W PoE++ support for advanced wireless access points and PTZ cameras
  • Zero-touch provisioning in Fortinet Security Fabric architectures
  • Flow-based intrusion prevention at switching layer

Compatibility extends exclusively to FortiSwitch 100F/200F/400F series devices running FortiOS 7.4.x. The firmware maintains backward compatibility with existing MSTP configurations while introducing enhanced stacking capabilities.

Key Features and Improvements

​​1. Security Upgrades​​

  • Patches CVE-2025-10871 (CVSS 8.9): Buffer overflow vulnerability in DHCP snooping module
  • Implements MACsec 256-bit encryption for inter-switch communications
  • Adds dynamic port isolation for rogue device containment

​​2. PoE Optimization​​

  • 30% improved power budgeting algorithm for mixed 802.3af/at/bt devices
  • Priority-based load shedding during power redundancy failures
  • Real-time per-port energy metrics via REST API

​​3. Fabric Integration​​

  • Auto-discovers FortiExtender 351F devices with 5G uplinks
  • Supports FortiManager 7.6.2 multi-tenancy templates
  • Enhanced NetFlow v9 export for FortiAnalyzer 7.2.3+ correlation

​​4. Protocol Enhancements​​

  • LLDP-MED extensions for VoIP device auto-classification
  • BFD sub-second failover for ECMP routing topologies
  • VXLAN gateway support with 16M virtual network identifiers

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Hardware Models FortiSwitch 148F-POE (FS-148F/FS-248F variants)
