Mini-Format Powerhouse: Your 202W PoE+ Power Pack
The UniFi USW-Ultra-210W is a true powerhouse in a compact package. Don't be fooled by its small size: with a massive PoE budget of 202 watts, provided by the included 210W Power Supply, this UniFi Switch from Ubiquiti is ready for the most demanding tasks. It effortlessly powers a whole arsenal of PoE devices – from high-resolution IP Cameras to modern Wi-Fi 6 WiFi Access Points and complete VoIP phone systems. By distributing up to 30W of PoE+ per port, your end devices always get the power they need to function stably and reliably.
Flexibility Redefined: Power via Adapter or Network Cable
The most outstanding feature of the USW-Ultra is its incredible flexibility in Power Supply. You can operate it conventionally with the powerful adapter to utilize the maximum PoE budget. However, the real magic unfolds with the ability to use the switch for installations without a power outlet. Simply connect port 8 to another PoE++ capable switch, and the USW-Ultra will be powered entirely via the Network cable. This opens up completely new installation possibilities in remote corners, drop ceilings, or places where running a power line would be difficult.
Built for Demanding Environments: The Robust UniFi Switch
Standard hardware quickly reaches its limits in unheated garages, attics, or warehouses. The USW-Ultra-210W is different. Its design is rated for an extended temperature range from -20°C to 60°C. Combined with the absolutely silent, passive cooling concept, it is not only robust but also the perfect companion for noise-sensitive environments like offices or recording studios. This managed Network switch delivers performance you can rely on, no matter where you deploy it.
Seamless Integration into Your UniFi Network
As a full member of the UniFi family, the USW-Ultra-210W is centrally managed via the intuitive UniFi Network Application. Here, you can configure VLANs, monitor the power consumption of each individual port, and control all Layer 2 features like Spanning Tree Protocol or port isolation. To operate the switch, you need a UniFi Dream Machine, a Cloud Key, or a self-hosted instance of the controller software. This way, you always maintain full control over your Network – from a single dashboard.
Strengths & Notes at a Glance
- Pro: Enormous PoE budget of 202W in a very compact, fanless Enclosure.
- Pro: Extremely flexible Power Supply via the included 210W adapter or alternatively, autonomously via PoE++ input on port 8.
- Pro: Robust operation in an extended temperature range (-20° to 60°C), ideal for non-air-conditioned environments.
- Pro: Absolutely silent operation thanks to a passive cooling concept, perfect for offices and living spaces.
- Note: The included 210W power supply, at 770g, is significantly heavier and larger than the switch itself and must be considered during installation.
- Note: Compared to other UniFi models, advanced L2 features like Link Aggregation (LAG) are missing.

Frequently Asked Questions (FAQ)
Can I operate the USW-Ultra-210W without the large power supply?
Yes, the switch can also draw its operating voltage from an incoming network cable via PoE+ or PoE++ (Port 8). However, the available PoE budget for the connected devices is then significantly lower (e.g., 42W with PoE++ input). This is sufficient for pure switch operation without PoE output.
What is the exact difference between the USW-Ultra, USW-Ultra-60W, and the USW-Ultra-210W?
The switch device itself is identical in all three models. The only difference is the included external power supply. The base model comes without a power supply, while the other versions are supplied with a 60W or 210W power supply, which directly determines the maximum available PoE budget.
Is the switch suitable for outdoor use?
No, the USW-Ultra is not designed for direct outdoor use and is not weatherproof. However, it can be used in protected, non-air-conditioned areas such as garages or covered patios, as long as it is protected from moisture. For full outdoor use, a model like the UniFi Switch Flex (USW-Flex) would be more suitable.
Do I need a UniFi Cloud Key or a Dream Machine to operate the switch?
Yes, the UniFi Network Application is mandatory for configuring and managing the switch. It can be run on a UniFi Dream Machine, a Cloud Key, or a local server. Without the UniFi software, the switch only functions as an unmanaged switch with no access to features like VLANs or PoE port management.
Does the switch support 2.5 Gigabit Ethernet?
No, all 8 ports of the USW-Ultra-210W are limited to 1 Gigabit Ethernet (1000 Mbps). For higher speeds, you would need to use a model from the UniFi Enterprise or Pro-Max series.
Can I use the full 202W of PoE power on a single port?
No, the power is distributed across the seven PoE output ports. Each individual port is limited to a maximum power of 30W by the PoE+ standard. The 202W is the total budget shared by all connected devices.
