Introduction to FSW_426E_FPOE_MG-v7-build0471-FORTINET.out Software
The FSW_426E_FPOE_MG-v7-build0471-FORTINET.out firmware file is a critical update for Fortinet’s FortiSwitch 400 Series devices, specifically designed to enhance Power over Ethernet (PoE) management and security protocols. Released under Fortinet’s Software-Defined Networking (SDN) framework, this build addresses operational stability and compliance requirements for enterprise networks leveraging PoE-driven infrastructure.
Compatible Devices:
- FortiSwitch 424E, 426E, 448E, and 424EPOE models running FortiSwitchOS v7.x.
- Requires minimum firmware FSW_426E_FPOE_MG-v7-build0400 for seamless upgrade.
Release Date:
- Officially published on Fortinet’s support portal on July 18, 2024, as part of Q3 2024 security and feature updates.
Key Features and Improvements
1. Advanced PoE Management
- Dynamic Power Allocation: Automatically redistributes power budgets across connected devices (e.g., IP cameras, VoIP phones) based on real-time demand, reducing energy waste by up to 30%.
- 802.3bt (Type 4) Support: Enables 90W PoE++ delivery per port for high-power devices like PTZ cameras and industrial IoT endpoints.
2. Security Enhancements
- CVE-2024-31988 Patch: Resolves a vulnerability (CVSS 7.5) where unauthenticated attackers could bypass PoE port controls via SNMPv3.
- MACsec Encryption: Adds hardware-accelerated encryption for PoE traffic between FortiSwitch and FortiGate NGFW, compliant with FIPS 140-2 Level 2.
3. Operational Stability
- LLDP-MED Optimization: Improves auto-configuration accuracy for Cisco IP phones and Aruba access points.
- PoE Port Diagnostics: New CLI commands (
diagnose poe-port-status,show poe-controller) provide granular insights into voltage fluctuations and cable faults.
Compatibility and Requirements
Supported Hardware
| FortiSwitch Model | Minimum Firmware | PoE Budget |
|---|---|---|
