Free Ethernet ports do not guarantee that the switch has enough PoE power for the next AP, camera or phone.
Small businesses often expand gradually, adding cameras, APs, phones, signage and IoT devices to the same PoE switch.
The physical port count can look healthy while the total PoE budget is already close to its limit. Future expansion needs both ports and power reserve.
Before you buy or replace hardware, review:
✓ Current powered devices
✓ Maximum device draw
✓ Total PoE budget
✓ Power-supply limit
✓ Expansion reserve
Plan port count and power budget together.
