Ubiquiti UniFi Switch Ultra (USW-Ultra)
A compact, Layer 2, 8-port GbE PoE switch with versatile mounting options. Seven ports supply PoE+ and the eighth is a PoE++ input, so the switch can be powered from an upstream PoE++ port and pass 42W of PoE on to cameras, access points and phones. This version ships without a power adapter: Ubiquiti lists the AC/DC adapter as excluded. It sits on a desk, mounts on a wall or attaches magnetically, managed in UniFi Network 8.0.28 and later.
Quick Glance
Key Features
Seven PoE+ outputs, powered by PoE++
Seven GbE ports deliver PoE+ at up to 30W per port, and one GbE port takes PoE++ input. Ubiquiti lists 42W of PoE availability with PoE++ input or a 60W PoE adapter, 16W with PoE+ input, 52W with a 60W AC adapter and 202W with a 210W AC adapter. PoE input powers the switch itself; PoE+/PoE++ input or AC power is required for PoE output.
Layer 2 switching in UniFi Network
16 Gbps switching capacity, 8 Gbps non-blocking throughput, a 12 Mpps forwarding rate, 256 VLANs and a 4,000-entry MAC address table. STP and RSTP, storm control, multicast and broadcast rate limiting, port isolation, port mirroring, jumbo frames and loop protection, managed in UniFi Network 8.0.28 and later.
Compact enclosure with three mounting options
The polycarbonate enclosure measures 203 x 76 x 33 mm and weighs 320 g, with a 45 g wall mount. It sits on a desk, mounts on a wall or attaches magnetically. With PoE++ input Ubiquiti rates it for -30 to 60° C operation, and heat dissipation is 31 BTU/hr excluding PoE output.
Detailed Specifications
Specifications are from Ubiquiti's official technical specifications and store listing for the Switch Ultra (USW-Ultra). Ubiquiti lists the AC/DC adapter as excluded for this version; PoE availability figures for adapter inputs apply only with a separately supplied adapter.
Need-to-Know
- This is the USW-Ultra without an adapter: Ubiquiti lists its AC/DC adapter as excluded. Power it from an upstream PoE++ port, or buy the Switch Ultra 60W or Switch Ultra 210W, which include an adapter.
- Total PoE output depends on how the switch is powered: 42W with PoE++ input or a 60W PoE adapter, 16W with PoE+ input, 52W with a 60W AC adapter and 202W with a 210W AC adapter.
- Ubiquiti states PoE input is supported for switch operation, with PoE+/PoE++ input or AC power required for PoE output. Each output port supplies up to PoE+ (30W).
- The 202W figure applies at 45° C. Ubiquiti reduces it to 161W (230V) or 121W (115V) at 60° C.
