Best Practices
PoE Planning Tips
Avoid common PoE deployment pitfalls with these engineering best practices.
Always Include Safety Margin
PoE devices can draw more power during startup or firmware updates. A 20% safety margin prevents unexpected brownouts.
Check Actual vs. Max Draw
Most devices draw less than their rated maximum. IP phones typically use 6-7W despite 802.3af supporting 15.4W.
Plan for Future Expansion
Leave headroom for adding cameras, APs, or IoT sensors. Upgrading switches mid-deployment is expensive.
