Ubiquiti UniFi USW-48-PoE — 48-Port Gigabit Managed PoE+ Switch (195W) with 4 SFP
When your network outgrows 24 ports, this is where you scale. The Ubiquiti UniFi USW-48-PoE packs 48 Gigabit ports, built-in PoE+, fiber-ready SFP uplinks, and silent fanless cooling into a single sleek 1U chassis — all managed through the famously intuitive UniFi platform. It’s the high-density, low-noise workhorse that powers entire offices, camera fleets, and AP deployments without breaking a sweat or breaking the silence.
48 Gigabit Ports — Half of Them Powered
Big networks need big port counts, and this switch delivers without the clutter of separate power supplies. It’s a configurable Gigabit Layer 2 switch with 48 Gigabit Ethernet ports, including 32 auto-sensing 802.3at PoE+ ports and 4 SFP ports, providing Gigabit PoE links to your RJ45 devices and Gigabit fiber uplink options to your enterprise network.
That’s a serious amount of powered connectivity. The 32 PoE+ ports deliver power directly to access points, IP cameras, VoIP phones, and other devices without external injectors, with each port supporting up to 15.4W (PoE) or 32W (PoE+) and a total PoE budget of 195W for flexible distribution across many endpoints.
- 48 × Gigabit Ethernet ports for high-density wired connectivity
- 32 × 802.3at PoE+ ports to power your devices over Ethernet
- 4 × 1G SFP ports for fiber uplinks up to 1 Gbps
- 195W total PoE budget to feed a large fleet of powered devices
High-Performance Switching, Zero Packet Loss
Speed and reliability at scale are non-negotiable, and the USW-48-PoE delivers both. It provides a total switching capacity of 104 Gbps with a forwarding rate of 77.38 Mpps, and offers the forwarding capacity to simultaneously process traffic on all ports at line rate without any packet loss.
Translation: even with all 48 ports busy, every camera streams, every file transfers, and every device stays responsive — no bottlenecks, no dropped packets.
Silent, Fanless Cooling for a 48-Port Switch
Here’s the standout surprise: a switch this big that you can’t hear. The UniFi PoE Switch features fanless, silent thermal cooling, so it can be deployed in areas where fan noise would be distracting. It’s a 48-port, Layer 2 PoE switch with a silent, fanless cooling system.
That means you can rack it in an open office, a studio, a classroom, or a small business back-room without a humming fan announcing its presence — high-density power and connectivity, total quiet.
Manage Everything the UniFi Way
This is the UniFi advantage: enterprise-grade control wrapped in an interface anyone can master. Managed and configured by the UniFi Network Controller with UniFi mobile app support, the USW-48-PoE offers an extensive suite of advanced Layer 2 switching protocols and features, including operation mode (switching, mirroring, or aggregate) per port.
And you can read its status without ever opening a laptop. The USW-48-PoE features a 1.3″ touch LCM to provide status information at a glance.
Enterprise Features That Keep Your Network Secure and Smooth
- 802.1X port-based authentication, MAC-based ACLs, MAC address blocking, and MAC-based port restrictions for tight device-access control
- DHCP Snooping and Guarding, IP-based ACLs, and network isolation to defend against common Layer 2 attacks
- QoS with Voice VLAN, LLDP-MED, egress rate limiting, flow control, storm control, jumbo frames, and port mirroring for fine-tuned, diagnosable traffic
- Support for up to 1,000 VLANs and a 16,000-entry MAC address table
Built Tough for the Rack
This switch is engineered for professional, long-term deployment. Built in a rack-mountable 1U form factor with compact 442 × 285 × 44 mm dimensions, its enclosure and mounting hardware are constructed from durable SGCC steel for long-term reliability. Powered by a universal 100-240VAC internal supply, it consumes just 45W excluding PoE output, with ESD/EMP protection rated at ±16kV air and ±12kV contact.
Who Is the USW-48-PoE For?
If your deployment has grown past what a 24-port switch can handle, this is your upgrade. It’s an ideal choice for dense PoE deployments in offices, campuses, retail locations, and hospitality environments. Think large offices, surveillance-heavy sites, multi-AP buildings, and growing businesses standardizing on UniFi.
A quick planning note: of the 48 ports, 32 support PoE+ output and all uplinks are 1G SFP, with a 195W total PoE budget — so map your high-draw powered devices accordingly. It’s managed through the UniFi Network platform.
The Bottom Line
The Ubiquiti UniFi USW-48-PoE combines 48 Gigabit ports, 195W of PoE+, fiber-ready SFP uplinks, line-rate performance, and whisper-quiet fanless cooling into one elegantly managed 1U package. Scale up your network, power your fleet, and enjoy the silence. Add the USW-48-PoE to your rack today and build the high-density, professionally managed backbone your growing network needs.
