Maximizing Network Uptime: A Closer Look at UniFi's Power Backup Technology

Published by Juan David Ramirez on 6th Feb 2025

Hey there, network enthusiasts! Juan David here, Flytec's Tech Support Lead and UniFi Certified Trainer. Let’s talk about something close to every geek’s heart: keeping your network running no matter what. We all know that a reliable network is essential, whether you're running a business, gaming, or just making sure your smart home devices don’t miss a beat. That’s where UniFi’s power backup solutions come in, offering seamless redundancy and peace of mind. Today, I’ll walk you through the UniFi SmartPower Redundant Power System (USP-RPS) and the Mission Critical switch (USW-Mission-Critical), two game-changing solutions for uninterrupted power.

USP-RPS: Power You Can Count On

First up, the USP-RPS, a 950W beast of a redundant power supply designed for rack-mounted UniFi devices. This isn’t just a backup; it’s your network’s best friend in times of trouble. Let me break it down: 

  • Massive Power Support: With 950W of DC power on tap, the USP-RPS can handle multiple devices without breaking a sweat. Think of it as the ultimate safety net for your rack-mounted UniFi gear.
  • (6) RPS DC ports: These ports allow you to connect a variety of UniFi devices, ensuring you have flexibility as your network grows.
  • At-a-Glance Monitoring: The 1.3” LCM touchscreen gives you all the vital stats—power status, connected devices, and system health, right at your fingertips.

For example, pairing the USP-RPS with a USW-Pro-Max-48 or UDM-PRO-MAX ensures centralized redundancy for core network devices, providing added peace of mind for critical operations.

Core Specifications at a Glance: 

  • Dimensions: 442.4 x 325.6 x 43.7 mm
  • Weight: 5.5 kg (without mount brackets), 5.6 kg (with mount brackets)
  • Max. Power Consumption: 995W
  • Supported Voltage Range: 100-240V AC 

In environments where every millisecond counts, the USP-RPS ensures your devices stay powered up and ready to perform. It’s like having a guardian angel for your network rack.

USW-Mission-Critical (120W): The Backup That Goes the Extra Mile

Now, let’s talk about the USW-Mission-Critical. This one’s a lifesaver for critical network deployments, featuring a built-in 368Wh Lithium-ion battery to keep your devices powered during outages. Here’s what makes it shine:

  • Battery Backup: The internal battery delivers uninterrupted power, bridging gaps during outages or giving you time to implement a fix.
  • PoE Versatility: With four GbE PoE+ ports and four GbE PoE++ ports, you can power everything from access points to VoIP phones. The total available PoE power is a hefty 120W.
  • Compact and Efficient: Measuring 442 x 480 x 44 mm and weighing 9 kg, the USW-Mission-Critical switch packs a lot of punch without taking up too much space.

For example, you could connect the UA-Door-Hub to the Mission Critical Switch, ensuring uninterrupted power to access control systems during an outage.

This device is perfect for situations where uptime isn’t just a preference—it’s a necessity. From small businesses to demanding enterprise setups, it ensures your network keeps humming along smoothly.

Handling High-Demand Networking Environments

Both the USP-RPS and the USW-Mission-Critical switch are built to handle the pressure of high-demand networks. Here’s how they get the job done: 

  1. Scalability That Grows With You: The USP-RPS can distribute its 950W power across multiple devices, while the USW-Mission-Critical ensures uninterrupted power for up to eight standalone devices.
  2. Redundancy You Can Trust: The USP-RPS provides centralized redundancy for rack-mounted setups, while the USW-Mission-Critical’s internal battery guarantees backup power on-site.
  3. Smart Monitoring: Both solutions offer intuitive ways to monitor performance. The USP-RPS’s LCM touchscreen and the USW-Mission-Critical switch’s network integration make it easy to stay on top of your power needs.

For hybrid setups, the USP-RPS provides centralized redundancy for rack-mounted devices, while the USW-Mission-Critical Switch complements it by ensuring uninterrupted operation for critical components, such as access control systems like the UA-Door-Hub. Together, they create a seamless power backup solution across diverse network requirements.

Why Choose UniFi Power Backup Solutions?

Let’s face it—downtime is a geek’s worst nightmare. With UniFi’s power backup solutions, you’re not just investing in hardware; you’re investing in peace of mind. The USP-RPS is perfect for rack-mounted setups, while the USW-Mission-Critical provides reliable backup for critical PoE-powered devices, such as access control systems. Together, they’re the dream team for maximizing uptime.

Conclusion
