- End of Life (EOL): 4/16/23

FortiSwitch-5203B Replacement
Replacing the FortiSwitch-5203B requires aligning switching capabilities with modern telemetry, automation, and segmentation needs across campus and data center environments.
Role of the FortiSwitch-5203B:
A high-capacity access and aggregation switch providing foundational connectivity for servers, virtual infrastructure, and user access.
Evolving Traffic Patterns:
East-west traffic, higher per-server throughput, and virtualized and containerized workloads require fabrics that handle bursty traffic and low-latency needs.
Modern Demands:
Today's networks require deep telemetry, zero-touch provisioning, automated policy enforcement, and integration with security fabric services.
Strategic Upgrade:
Adopt fabric-ready switching integrated with security and orchestration, offering scalable port configurations and automation tools to improve resilience and efficiency.
Understanding Fortinet's EOL Policy | End of Life Risks
Every Fortinet product follows a defined lifecycle, moving through the following stages:

- General Availability (GA): The product is released and actively sold and supported.
- End of Sale (EOS): The device is no longer available for purchase from Fortinet or authorized partners.
- End of Life (EOL): Feature development and most firmware updates stop.
- End of Support (EOSL): Fortinet ends all official support, security patches, and RMA services.
Why This Matters for Your Business
Understanding where your hardware sits in this lifecycle helps you:
- Plan timely upgrades before critical support ends.
- Ensure security compliance and avoid audit failures.
- Maintain operational continuity with fully supported hardware.
Risks of Continuing to Use EOL Hardware
When a firewall or security appliance reaches End of Life, the risks of keeping it in production increase dramatically
No Security Patches
Outdated devices won’t receive updates, leaving your network exposed to new vulnerabilities.
Lack of Vendor Support
Once support ends, there’s no access to Fortinet’s technical resources or RMA services.
Compliance Failures
Auditors may flag unsupported hardware as a violation of security and industry standards.
Operational Instability
Legacy devices may struggle with modern workloads, encrypted traffic, and cloud integrations.
