16-Port Managed PoE Switch

The Ubiquiti Networks USW-16-POE is a rackmount Layer 2 switch with sixteen Gigabit RJ45 ports and two 1G SFP uplinks. Eight ports provide PoE+ power with a total budget of 42 W. A fanless design ensures silent operation for office or quiet environments.

Suits Small PoE Deployments, Not High-Power Needs

This switch fits networks powering access points or cameras that stay within the 42 W budget. Builders needing more PoE ports or a larger power reserve for devices drawing higher wattage should consider a model with a bigger budget.

42 W Total PoE Budget Decides Fit

The single specification that determines suitability is the 42 W PoE power budget. If the combined draw of all powered devices exceeds this figure, the switch cannot support the deployment.

Questions about this item

Should I choose the 16-port or 24-port model for a small office needing PoE+ on up to 10 devices?

The USW-16-POE provides eight PoE+ ports with a 42 W budget, while the 24-port model offers 16 PoE+ ports and 95 W; pick the 24-port if you need more powered ports or higher total power.

What does the 18 Gbps non-blocking throughput mean when the switch is fully populated?

It means all 16 RJ45 ports and both SFP uplinks can run at 1 Gbps simultaneously without internal congestion, giving 18 Gbps of aggregate wire-speed switching.

The SFP ports are 1 Gbps — does that cap uplink speed in a 10 Gbps backbone?

Yes, the two SFP ports operate at 1 Gbps, so uplinks are limited to 1 Gbps each; they cannot negotiate 10 Gbps links.
