Ubiquiti UniFi Ultra Switch (USW-Ultra)

The UniFi USW-Ultra is a compact, weather-resistant 8-port Gigabit switch with 7 PoE+ outputs, flexible PoE++ or adapter-based input, Layer 2 management, and UniFi Controller support—ideal for modern edge deployments.:

📌 Overview & Ports

• Form Factor: Compact desktop/wall/magnetic mount, polycarbonate enclosure
• Dimensions: 203 × 76 × 33 mm
• Weight: ~320 g (device) + 45 g (mount plate)
• Ports:
  • 8 × 1 GbE RJ45 (7 PoE+ outputs, 1 PoE++ input)

💡 Power & PoE

• PoE++ In: Delivers up to 42 W total output to downstream devices
• PoE+ In: Delivers up to 16 W output
• 60 W AC Adapter: Includes 60 W DC input—provides 42 W PoE output
• 210 W AC Adapter: Provides up to 202 W PoE output
• Device Power Draw: ~9 W (when PoE-powered) or ~8 W (with DC adapter), excluding PoE load
• Voltage Input Range: 44–57 V DC via PoE++ or adapter

🔁 Performance

• Switching Capacity: 16 Gbps
• Non‑blocking Throughput: 8 Gbps
• Forwarding Rate: ~12 Mpps

🔧 Layer 2 Features

• VLANs: Up to 256
• Supports: STP/RSTP, flow & storm control, port isolation & mirroring, jumbo frames, loop protection, egress rate limiting
• MAC Table Size: 4,000 entries

🌡️ Environmental

• Operating Temperature:
  • With PoE++ input: –30 °C to +60 °C
  • With 60 W adapter: –20 °C to +45 °C
  • With 210 W adapter: –20 °C to +60 °C
• Humidity: 10–90% non-condensing
• Certifications: CE, FCC, IC; NDAA compliant

⚙️ Management & Compliance

• Management: Ethernet in-band via UniFi Network Controller (v8.0.28+)
• Class: Fully managed Layer 2 switch
• Certifications: CE, FCC, IC, NDAA compliant

🛠️ Real‑World Notes

• Multiple SKUs (USW‑Ultra, USW‑Ultra‑60W, USW‑Ultra‑210W) differ only in included adapter—internals remain identical
• Powered via standard PoE++ injector or 60 W adapter; PoE+ injectors will power switch only—won’t enable PoE+ output functionality
