Description

The USW-Ultra-210W packs high PoE capacity into a sleek, portable form—a perfect fit for spaces like compact offices, surveillance hubs, or wireless edge nodes. The switch provides seven PoE+ ports (up to 30 W per port) alongside a PoE++ input port. Thanks to the included 210 W external AC adapter, it supports up to 202 W PoE output at 45 °C (water-tight lab conditions).

Power performance remains robust even under heat: at 60 °C, PoE output adjusts to 161 W (at 230 V AC) or 121 W (at 115 V AC). Switching performance is just as impressive, delivering 16 Gbps switching capacity, 8 Gbps non-blocking throughput, and 12 Mpps forwarding rate—all in a miniature 203 × 76 × 33 mm polycarbonate chassis.

Layer 2 features include VLAN support (up to 256), port mirroring, port isolation, storm control, jumbo frames, and more. Mounting is versatile—desktop, wall, or magnetic.

Application

Compact PoE hub for edge deployments, powering cameras, APs, VoIP phones—perfect for tight spaces with high PoE demand like kiosks, retail displays, or IoT hubs.
