Ubiquiti UniFi Switch Ultra - Compact PoE-Powered 8-Port Managed Switch with 42W PoE Output
The Ubiquiti UniFi Switch Ultra (USW-ULTRA) is a compact 8-port Gigabit managed switch that runs entirely off PoE input from an upstream switch. No power adapter, no outlet at the install location. The switch draws power over its Ethernet uplink and passes PoE to connected devices with a 42W total budget across seven PoE+ ports and one PoE++ port, making it a drop-anywhere edge switch for desks, conference rooms, and wall-mount installs.
The Switch Ultra fills the gap between the UniFi Lite 8 PoE and the Switch Flex in the UniFi switch lineup. The Lite 8 PoE needs a wall outlet and delivers 52W; the Ultra trades that extra PoE budget for outlet-free deployment at 42W. If your install location has an Ethernet run from a PoE++ switch but no convenient power outlet, the Ultra is the answer.
Where the Switch Ultra Fits
- Under desks and behind conference room displays where 2-4 devices (AP, phone, camera, laptop dock) need PoE and wired connectivity but there is no open outlet, and running a power cable would mean visible cord management
- Hallway and ceiling installs where a single Ethernet run from a PoE++ switch in the MDF powers the Ultra behind a drop ceiling or wall plate, and it fans out PoE to a nearby AP, camera, and door controller
- Retail and hospitality edge locations like POS stations, kiosks, and check-in desks where a compact wall-mount switch adds ports without requiring electrical work or a dedicated power adapter
What the Switch Ultra Delivers
- PoE-powered deployment: The switch itself runs off PoE from an upstream PoE++ port. No wall adapter, no outlet, no electrician. One Ethernet cable from the upstream switch provides both data and power to the Ultra and its connected devices.
- 42W PoE budget across 8 ports: Seven PoE+ ports and one PoE++ port share a 42W total budget. Enough to power an AP, a camera, a phone, and a few wired devices from a single switch that needs no outlet of its own.
- Layer 2 managed: 802.1Q VLANs, IGMP snooping, port mirroring, and spanning tree managed through UniFi Network. Same dashboard, same VLAN config, same firmware updates as every other UniFi switch in the deployment.
- Fanless and compact: Polycarbonate enclosure (8 x 3 x 1.3 in., 11.29 oz) with no moving parts. 9W switch power consumption. Silent operation for open offices, hotel rooms, and anywhere noise matters.
- Wall mountable: Mount it behind a display, under a desk, or on a wall in a closet. The compact footprint disappears into the install location.
