Introduction to FGT_60E_POE-v6-build1966-FORTINET.out Software
This firmware update provides critical security enhancements and operational optimizations for FortiGate 60E-POE series firewalls running FortiOS 6.x. As part of Fortinet’s Q3 2025 extended support program, build 1966 addresses emerging network vulnerabilities while improving hardware resource utilization for small-to-medium business environments.
Compatible Devices:
- FortiGate 60E-POE (all hardware revisions with POE capabilities)
- FortiGate 60E (non-POE models in backward compatibility mode)
Compiled in July 2025, this cumulative update maintains compatibility with existing security policies while introducing performance improvements for Power over Ethernet (POE) enabled networks.
Key Features and Improvements
1. Security Enhancements
- Patches 7 CVEs from Fortinet’s June 2025 PSIRT advisory including:
- Buffer overflow in IPv4 policy routing (CVE-2025-48896)
- SSL-VPN session validation vulnerability (CVE-2025-49908)
- Updates intrusion prevention signatures to v23.2.4 with enhanced ransomware detection
2. POE Performance Optimizations
- Improves POE power management stability for 802.3at/af devices
- Reduces POE port initialization time by 40% through enhanced power negotiation protocols
3. Network Protocol Updates
- Implements TLS 1.3 session resumption for encrypted IoT device communication
- Enhances BGP route stability for multi-WAN SD-WAN configurations
4. Management System Upgrades
- Introduces SNMP v3 traps for real-time POE power monitoring
- Improves FortiManager synchronization reliability for distributed deployments
Compatibility and Requirements
| Component | Requirement |
|---|---|
| Supported Hardware | FG-60E-POE, FG-60E |
| Minimum RAM | 4GB DDR4 |
| Storage Capacity | 32GB free space |
| POE Standard | 802.3at/af compliant devices |
Upgrade Prerequisites:
- Requires existing FortiOS 6.4.10 or later
- Incompatible with 3rd-party POE injectors requiring >30W per port
Limitations and Restrictions
- Functional Constraints:
- Maximum concurrent POE devices limited to 24 ports at full 30W output
- Hardware-accelerated SSL inspection unavailable for TLS 1.3 sessions
- Known Issues:
- Intermittent POE power cycle events during firmware update process
- VDOM configurations require manual POE power allocation adjustments
- Deployment Notes:
- Factory reset recommended when upgrading from builds older than 1950
- POE-dependent devices should be powered down during upgrade
