Upcoming Cisco Meraki End of Life

Is Your Network Ready for the MS350/MS390 Sunset? As businesses increasingly rely on robust and secure network infrastructure, it’s critical to stay ahead of end-of-life (EOL) deadlines. Cisco Meraki has officially announced that multiple switch and appliance models—including the widely used MS350 and MS390 families—will reach end-of-life status between February and August 2025.

What’s Happening?

Cisco Meraki’s hardware lifecycle policies are clear: once a product is declared EOL, support and software updates are phased out shortly after. For MS350, MS390, and other select models, this means:

• EOL milestone: Early to mid–2025

• End of support: Service and updates will cease between February and August 2025, depending on the exact model and revision

If these switches are powering your critical infrastructure—whether in campus environments, branch offices, or core distribution layers—now is the time to act.

What Does This Mean for Your Organization?

• No more firmware or security updates

Without updates, vulnerabilities may go unpatched, exposing your network to risk.

• Limited hardware replacements

RMAs (Return Merchandise Authorizations) will no longer be processed after EOS, impacting your ability to replace failed devices.

• Compliance risks Unsupported network hardware may fall outside the scope of compliance frameworks like ISO 27001, HIPAA, or SOC 2.

• Vendor lock-in pressure

Last-minute transitions might push organizations into costly upgrades without a proper evaluation process.

What Should You Do?

1. Audit your hardware

Use the Meraki dashboard or asset management tools to identify which devices are affected.

2. Plan a phased replacement strategy

Consider newer models like the MS390 Gen 2, MS425, or even cloud-first alternatives, depending on your architecture.

3. Evaluate network redesigns

EOL transitions offer a chance to re-assess topology, redundancy, and segmentation best practices.

4. Engage your vendor or MSP early

Procurement and lead times can be unpredictable—plan now to avoid delays.

5. Document lifecycle policies

Ensure your IT policies include hardware lifecycle tracking so you're never caught off guard.

Final Thoughts

EOL isn’t just a hardware milestone—it’s a strategic inflection point. By getting ahead of these deadlines, organizations can turn forced upgrades into opportunities for innovation, performance gains, and improved resilience. Don’t wait for support to vanish. Start your transition plan today.
