3 Ways to Cut Your Network Switch (8-Port) Energy Bill
- 🌱
Enable Energy Efficient Ethernet (IEEE 802.3az) in the switch settings if supported — it reduces idle port power.
- 💡
Unplug Ethernet cables from unused ports — active link negotiation on idle ports draws unnecessary power.
- ⚡
Use a smaller switch if you only need 4 ports — 8-port switches draw more power even with unused ports.
Startup Surge Information
Network switches are solid-state devices with no motors, drawing very low, consistent wattage.
