UniFi Switch Ultra (USW-Ultra): Compact and Versatile Managed PoE+ Switch (8× GbE, up to 202W PoE Budget)

The Ubiquiti UniFi Switch Ultra (USW-Ultra) is a fully managed Layer 2 Gigabit switch featuring 8 RJ45 ports, 7 of which support PoE+ (802.3at), delivering up to 202W of total PoE power depending on the chosen power source. Designed for flexibility, silent operation, and simple deployment, it’s the perfect solution for offices, shops, smart homes, or any location where compact PoE switching is needed.

⚡ The Most Flexible PoE+ Switch in the UniFi Ultra Line

The USW-Ultra redefines the concept of compact PoE switching. With 8 Gigabit Ethernet ports — including 7 PoE+ outputs (up to 30W per port) — it can easily power WiFi 6/7 access points, UniFi Protect cameras, VoIP phones, and other PoE-enabled devices, while providing full UniFi Network integration for monitoring and control.

🔌 Unmatched Power Flexibility

Adapt the USW-Ultra to any power environment:

• PoE In (Port 1):
  Power the switch via PoE+ (802.3at) for up to 16W PoE output, or PoE++ (802.3bt) for up to 42W PoE output, eliminating the need for a local power adapter.

• Optional 60W AC Adapter:
  Provides up to 42W total PoE budget, ideal for powering small clusters of access points or cameras.

• Optional 210W AC Adapter:
  Unlocks the switch’s full 202W PoE budget, enabling simultaneous power delivery to multiple PoE+ devices in larger deployments.

This flexible approach allows the USW-Ultra to scale from a simple desk switch to a compact PoE distribution hub in professional installations.

🧩 Compact, Silent, and Easy to Mount

With its ultra-compact form factor, the USW-Ultra fits anywhere — on a desk, wall, or even magnetically mounted (with optional accessory). Its fanless design ensures completely silent operation, making it ideal for noise-sensitive spaces such as offices, studios, or living rooms.

🛠️ Centralized UniFi Network Management

Managed through the UniFi Network Controller, the USW-Ultra integrates seamlessly into your UniFi ecosystem.
Configure VLANs, monitor per-port PoE usage, enable STP/RSTP, set up link aggregation (LAG), and view real-time traffic and port status, all from a single unified dashboard — web or mobile.
