Frequently Asked Questions
The US-8-150W includes eight 10/100/1000 RJ-45 ports with PoE capabilities and two hot-swappable 1 Gbps SFP ports for fiber uplinks, supporting flexible copper and fiber connectivity in small deployments.
Is this answer helpful?
The switch has a 150W internal power supply for PoE output. Ports default to auto-sensing PoE+ (802.3af/at). 24V passive PoE is supported but must be enabled manually per port after confirming device compatibility.
Is this answer helpful?
Install UniFi Controller software (v5+ recommended) locally or use a UniFi Cloud Key. Ensure the network uses DHCP, then locate the device in the Controller dashboard under Devices and click Adopt to integrate it into your UniFi network.

The US-8-150W supports shelf or wall mounting using included brackets and screws. Maintain at least 20 mm clearance near ventilation holes, do not stack the unit, and avoid exposure to moisture to prevent fire or shock hazards.
Is this answer helpful?
Yes, the two SFP ports are hot-swappable and support 1 Gbps SFP fiber modules. Use compatible modules (single-mode or multimode) per vendor recommendations for fiber runs and distances.

Advantages and Disadvantages
Advantages
- Compact desktop form factor with eight Gigabit RJ-45 ports and two 1 Gbps SFP uplinks for flexible connectivity.
- 150W internal power supply delivering PoE+ to multiple devices and manual 24V passive PoE support for legacy gear.
- Seamless integration with UniFi Controller for centralized adoption, per-port PoE control, firmware updates, and topology mapping.
- Clear multi-color LEDs for system, port speed/activity, and PoE status simplify diagnostics and device locating.
- Includes wall and shelf mounting hardware; robust regulatory compliance and ESD protection for commercial deployments.
Disadvantages
- 150W total PoE budget may limit the number of high-draw PoE+ devices that can be powered simultaneously.
- 24V passive PoE must be manually enabled and can damage unsupported devices if used incorrectly.
- Not rack-mountable and must not be stacked; limited to shelf or wall mounting which may restrict placement options.
- One-year limited warranty with exclusions; RMA required for returns and removal/reinstallation costs not covered.
- Requires UniFi Controller (v5+ recommended) and a DHCP-enabled network for easy adoption, adding management dependency.
Product Description
Ubiquiti UniFiSwitch 8 Desktop Gigabit Managed Switch, 8x RJ-45, 150W PoE+
The Ubiquiti UniFiSwitch 8 (US-8-150W) is a compact, desktop-managed Gigabit switch designed for small offices, branch deployments, and prosumer networks requiring reliable PoE delivery and simple centralized management. With eight 10/100/1000 RJ-45 ports and two 1 Gbps SFP uplinks, the switch combines full Gigabit connectivity with flexible fiber uplink options. A 150W internal power supply delivers PoE+ to compatible devices, while also supporting 24V passive PoE for legacy equipment when enabled manually.
This model integrates with the UniFi Controller ecosystem for unified monitoring and configuration. The ARM Cortex-A9 processor, 256MB DDR3 RAM, and UniFi Controller support provide a responsive interface for adopting the switch, adjusting per-port PoE modes, and viewing link/activity status through multi-color LEDs. The system LED indicates device state—initializing, adopted, or in-locate—while individual RJ45 and SFP LEDs show link speed, activity, and PoE status.
Physically compact at roughly 204 x 43 x 235 mm, the US-8-150W supports shelf or wall mounting via included brackets and screws. Important hardware and safety considerations include ventilation clearance (minimum 20 mm), prohibition on stacking, and adherence to indoor moisture and electrical safety guidelines. SFP ports are hot-swappable and accept compatible 1 Gbps fiber modules for long-distance links.
Software setup relies on the UniFi Controller (v5+ recommended) running locally or via a Cloud Key. A DHCP-enabled network simplifies adoption; the Controller dashboard lets you discover and adopt the switch and configure individual port behaviors including PoE Off, 24V Passive, or PoE+. UniFi’s controller-based workflows allow firmware upgrades, device locating, and centralized topology maps.
Built to commercial safety and regulatory standards (CE, FCC, IC) and tested for ESD/EMP protection, the US-8-150W includes a one-year limited warranty covering defects in materials and workmanship. The warranty has standard exclusions—modifications, improper cabling, third-party firmware, and misuse—and requires RMA procedures for returns.
Notes:
- Default ports 1–8 auto-sense PoE+; enable 24V passive PoE manually after confirming device compatibility.
- Maintain at least 20 mm clearance for ventilation; do not stack units.
- Use CAT5 or higher cabling for all Ethernet runs and follow local installation codes.
