Key Features and Benefits

1. Massive PoE Power and Flexibility

With a 600W total PoE budget, this switch can power an entire ecosystem of devices. The 8 dedicated PoE++ (802.3bt) ports are crucial for powering high-demand equipment like:

• UniFi Access Hub and Door Access Locks

• UniFi LED Lights

• High-performance PTZ cameras

• Other 802.3bt devices like thin clients and digital signage.

The 40 PoE+ ports efficiently handle all standard PoE devices, making it a true all-in-one power and data solution.

2. High-Speed Connectivity and Future-Proofing

The four 10G SFP+ ports are the standout feature for performance. Use them for:

• Uplinks to a core router like the Dream Machine Pro/SE.

• Aggregated Links to another switch for a high-bandwidth backbone.

• Direct Connections to 10G servers or Network Attached Storage (NAS) devices.

3. Advanced L3 Management and Security

As a Layer 3 switch, the USW-Pro-48-POE offloads routing tasks from your security gateway, improving overall network performance.

• Inter-VLAN Routing: Route traffic between different VLANs directly at the switch level.

• Static Routing: Implement advanced network paths.

• Comprehensive Security: Features like MAC filtering, ACLs (Access Control Lists), and storm control protect your network from unauthorized access and malicious traffic.

4. Enterprise-Grade Reliability

• Dual, Hot-Swappable Power Supplies: Ensure maximum uptime. In case of a PSU failure, the secondary takes over instantly. You can also connect an external UPS to both for complete power protection.

• Fanless (Silent) Design: In low-to-moderate load and temperature conditions, the fans remain off, making it suitable for office environments.

• Rack-Mount Design: A standard 1U form factor for clean integration into any server rack.

5. Seamless UniFi Ecosystem Integration

Managed through the intuitive UniFi Network Controller, this switch offers a single-pane-of-glass view for your entire network. You can:

• Adopt the switch in seconds.

• Monitor power usage, traffic, and client statistics in real-time.

• Configure all ports, VLANs, and PoE settings with ease.

• Set up and manage other UniFi devices (APs, cameras, phones) from the same interface.

Who Is This Switch For?

The UniFi Switch PRO 48 PoE is designed for environments that require high port density, substantial PoE power, and advanced networking features.

Ideal Use Cases:

• Medium to Large Businesses: As a core switch for an office with a large number of PoE devices.

• Schools and Universities: To power classrooms full of access points and cameras.

• Advanced Home Labs / Prosumers: For users with extensive smart home setups, servers, and high-speed networking needs.

• SMBs with High-Density Wi-Fi: Deploying dozens of Wi-Fi 6/6E access points.

• Surveillance-Intensive Environments: Powering and connecting a large number of high-resolution IP cameras.

Frequently Asked Questions (FAQ)

Q: What is the difference between PoE+ and PoE++?
A: PoE+ (802.3at) delivers up to 30W per port, perfect for APs, most cameras, and VoIP phones. PoE++ (802.3bt) delivers up to 60W (Type 3) or even 100W (Type 4) per port, designed for high-power devices like access control systems and LED lights.

Q: Can I use this switch without a UniFi Controller?
A: For initial setup and full management, a UniFi Network Application (hosted on a Cloud Key, Dream Machine, or your own server) is required. It can adopt a standalone configuration via the mobile app for basic setup.

Q: Does it support Link Aggregation (LAG)?
A: Yes, you can create LAG groups across multiple ports to combine bandwidth and provide redundancy.

Q: What is the real-world power consumption?
A: Without any PoE load, the switch itself consumes ~40-50W. The total power draw will be the switch consumption plus the combined power of all your connected PoE devices, up to the 600W budget.

Q: Is there a non-Pro version?
A: Yes, the standard USW-48-POE has a lower PoE budget (370W) and lacks the PoE++ ports, 10G SFP+ ports, and Layer 3 features.

Conclusion

The UniFi Switch PRO 48 PoE (USW-Pro-48-POE) is not just a switch; it’s the foundation for a powerful, scalable, and professional network. Its massive 600W PoE budget, combination of 48 GbE ports with 4x 10G SFP+ uplinks, and advanced Layer 3 capabilities make it an unbeatable choice for anyone building a serious, future-proof infrastructure. If your network demands high performance, reliability, and centralized management, this is the switch to get.
