Ubiquiti USW-ULTRA-210W UniFi Network Switch

Ubiquiti USW-ULTRA-210W UniFi Network Switch

Overview

The Ubiquiti USW-ULTRA-210W is a compact eight-port gigabit switch designed for small-to-medium network deployments requiring Power over Ethernet (PoE) capability. This switch delivers 16 Gbps switching capacity with 8 Gbps non-blocking throughput and a 12 Mpps forwarding rate, making it suitable for edge locations, remote sites, and distributed infrastructure environments. The unit supports up to 256 VLANs for network segmentation and NDAA compliance certification for sensitive deployments.

Key Features

The USW-ULTRA-210W ships with an external AC/DC power adapter rated at 210W, enabling full PoE++ output delivery across its eight ports. The device consumes only 9W in normal operation (excluding PoE output), optimizing power efficiency in remote deployments. Its compact polycarbonate enclosure measures 203 x 76 x 33 mm and weighs 320 grams, allowing flexible mounting options including desktop placement, wall mounting, or magnetic surface attachment. The switch operates reliably across extended temperature ranges from -30 to 60°C, supporting outdoor and harsh-environment installations. Management occurs through standard Ethernet connectivity, integrating seamlessly with Ubiquiti's UniFi controller ecosystem.

Deployment Scenarios

Deploy the USW-ULTRA-210W at network edge locations where compact form factor and high PoE capacity are critical. Common use cases include wireless access point aggregation, IP camera clusters, and distributed IoT device networks. The switch's 210W PoE budget accommodates multiple high-power devices simultaneously—ideal for powering surveillance systems, enterprise access points, or industrial sensors without additional power infrastructure.

Network Integration

This switch integrates directly into UniFi-managed networks, communicating with UniFi controllers for centralized administration. The device supports standard 802.1Q VLAN tagging for network isolation and traffic segregation. With 8 Gbps non-blocking throughput per port pair, the USW-ULTRA-210W ensures consistent performance without congestion, even under sustained data transfer between connected devices. The Ubiquiti USW-ULTRA-210W maintains full backward compatibility with existing UniFi infrastructure.

Installation Notes

The switch arrives with the 210W AC/DC adapter included; no additional power supply procurement is necessary for standard deployments. Alternatively, the unit accepts PoE++ input from an upstream switch (50–57V DC range), enabling daisy-chaining in larger networks. Wall mounting and magnetic attachment options accommodate confined spaces and equipment racks. The device holds CE, FCC, IC, and Anatel certifications, ensuring regulatory compliance across multiple markets. Connect the management port to your network for UniFi controller discovery and ongoing firmware updates.

Karl Wilson, Infrastructure Engineer

"The USW-ULTRA-210W fills a genuine gap in compact switching. Organizations deploying remote surveillance or distributed IoT often struggle with power budgets and physical space constraints. This switch solves both: 210W PoE output in a device smaller than a paperback book. The NDAA compliance is significant for federal and defense contracting work. I've deployed the USW-ULTRA-210W in ten-site networks where each location needed local switching and PoE aggregation without rack space. The -30 to 60°C operating range means it survives outdoor cabinet installations without thermal management. If you're standardizing on UniFi infrastructure and need edge-location switching, the USW-ULTRA-210W is the logical choice."
