Imagine connecting 48 devices, each receiving both data and power through a single Ethernet cable. That’s the magic of the USW-Pro-48-PoE. It boasts 48 Gigabit Ethernet RJ45 ports, specifically configured with a powerful combination:

• 40 ports with 802.3af/at (PoE+): Delivering up to 30W per port, perfect for standard access points, IP phones, and most surveillance cameras.
• 8 ports with 802.3bt (PoE++): These are your heavy lifters, capable of providing up to 64W per port. This is essential for high-power devices like advanced PTZ cameras, LED lighting, or even compact client devices.

With a substantial total PoE budget of 600W, this managed switch ensures that even the most power-hungry deployments are well-catered for, simplifying your cabling infrastructure and reducing the need for separate power outlets. This intelligent power delivery is a cornerstone of an efficient network.

Unleashing Speed with 10G SFP+ Uplinks

While Gigabit Ethernet handles most local traffic admirably, high-capacity networks often require even faster connections to the backbone or other switches. The USW-Pro-48-PoE addresses this with four 10G SFP+ ports. These fiber uplink ports are vital for:

• Connecting to network backbone: Ensuring high-speed data flow to your core switches or server infrastructure.
• Long-distance links: Extending network segments over greater distances using fiber optic cables.
• Aggregation: Consolidating traffic from multiple switches without performance degradation.

These 10 Gigabit uplinks provide a significant boost in throughput, enabling the USW-Pro-48-PoE to handle intensive data loads and ensuring your network remains responsive, even under peak demand. It’s about building a highway for your data, not just a two-lane road.

Advanced Layer 3 Capabilities: Beyond Basic Connectivity

Many switches operate at Layer 2, handling basic frame forwarding within a single broadcast domain. However, the USW-Pro-48-PoE elevates your network management with robust Layer 3 capabilities. What does this mean for you?

• Inter-VLAN Routing: This feature allows devices on different Virtual Local Area Networks (VLANs) to communicate with each other directly through the switch, rather than relying on an external router. This significantly improves performance and reduces latency for inter-VLAN traffic.
• Static Routing: Enables you to define fixed paths for network traffic, offering precise control and optimizing data flow in specific scenarios.
• DHCP Server Functionality: The switch can assign IP addresses to devices on your network, simplifying client configuration and management.

These Layer 3 features empower you to segment your network more effectively, enhance security by isolating traffic, and optimize routing paths, making the USW-Pro-48-PoE a truly enterprise-grade solution. As network expert Evelyn Reed, a veteran in data center architecture, once shared with me, “Effective Layer 3 switching isn’t just about speed; it’s about intelligent traffic management that fundamentally strengthens your network’s security posture and operational efficiency.”

Quiet Operation and Redundant Power for Reliability

Network equipment, especially in larger deployments, can sometimes be a noisy affair. However, the USW-Pro-48-PoE is designed with “near-silent cooling.” Its integrated fans feature PWM (Pulse Width Modulation) control, intelligent air ducts, and temperature sensors to ensure optimal cooling without the distracting hum. This makes it suitable for deployment in various environments, including offices or classrooms, not just server rooms.

Furthermore, network reliability is paramount. The USW-Pro-48-PoE supports an external DC input interface, specifically the proprietary USP RPS (UniFi SmartPower Redundant Power System) interface. This offers a crucial redundant power feature, providing backup if the internal power supply unit (PSU) fails. This level of foresight in design means maximum uptime and peace of mind for mission-critical operations.
