Compact 8-port PoE switch

The Ubiquiti USW-ULTRA-210W is an unmanaged Layer 2 switch with eight GbE RJ45 ports in a desktop form factor. It supplies PoE+ on seven ports and accepts PoE++ input on the eighth, making it suited for small networks powering access points, cameras or VoIP phones.

Sustained 202 W PoE budget

The included 54 V 3.9 A adapter delivers 202 W of total PoE power for continuous operation across all powered ports. Non-blocking throughput reaches 8 Gbps with a 16 Gbps switching capacity, so every port can run at line rate without head-of-line blocking during extended loads.

Silent fanless operation

The unit has no moving parts and runs from -20 °C to 60 °C with the 210 W adapter, or -30 °C to 60 °C when powered via PoE++. Power draw stays within the adapter rating, and the compact 203 x 76 x 33 mm enclosure mounts on a desk or wall without audible noise.

Questions about this item

Does the 210 W adapter make the switch run hot or loud during all-day use?

The unit operates from -20 to 60 °C with the included 210 W adapter and has no fan, so it stays silent and within its rated temperature range under continuous load.

What must I already have to power the seven PoE+ output ports?

The included 54 V, 3.9 A adapter supplies up to 202 W of PoE budget; no separate injector or extra power supply is needed for the PoE+ ports.

Can the single PoE++ input port be fed by an existing PoE+ injector to run the switch itself?

Yes, the switch accepts PoE++ or PoE+ input on port 1 for its own operation, but PoE output to other devices still requires the AC adapter.
