Ubiquiti UniFi Ultra Switch 7xPoE GbE, 1x PoE input. 42W (USW-Ultra)

The Ubiquiti USW-Ultra, released in early 2024, is a versatile, entry-level Layer 2 managed Gigabit Ethernet switch optimized for powering UniFi access points, cameras, and other PoE devices in compact spaces like offices, retail, or home setups. It features 8 x 1 GbE RJ45 ports (7 for PoE output at 30W each, 1 dedicated PoE input), delivering a total 42W PoE budget via PoE input (or 16W with PoE input) and a non-blocking throughput of 8 Gbps with 16 Gbps switching capacity for lag-free performance. Measuring 203 x 76 x 33 mm (8 x 3 x 1.3″) and weighing ~500 g, its slim, fanless design supports multiple mounting options: desktop, wall, or pole via included hardware, ensuring silent operation and flexible deployment. Powered by a quad-core ARM processor and 512 MB DDR3 RAM, it supports advanced features like STP/RSTP, port isolation, VLANs (up to 255), QoS, IGMP snooping, and jumbo frames, all configurable via the UniFi Network app with Bluetooth setup and zero-touch provisioning. It accepts power from a 54V DC adapter (not included), PoE (802.3at), or PoE (802.3bt) on port 8, with max consumption of 7W (no PoE) to 52W (full load). Strengths include its all-PoE port layout for simplified cabling and scalability up to 30 UniFi devices, but it lacks multi-gig ports and requires external power sourcing—perfect for budget-conscious expansions in UniFi ecosystems without rack space.
