Fanless 48-Port Gigabit Managed Switch with Four SFP Uplinks for High-Density Non-PoE Wiring Closets
The Ubiquiti UniFi Switch 48 (USW-48) is a fanless 1U rack-mount Layer 2 managed switch with 48 Gigabit Ethernet ports, four 1G SFP uplink slots, and a 1.3-inch front-panel touch LCM display. It provides managed Gigabit connectivity for high-density deployments where all connected devices have their own power source and the switch handles data switching only.
The USW-48 fills the need for 48 managed ports in a single 1U slot without PoE overhead, fan noise, or excessive power draw. Four SFP slots provide redundant fiber uplinks to the core or allow LAG aggregation for aggregate throughput beyond a single Gigabit link. The same fanless, silent design as the USW-24 scaled to 48 ports for floors and closets that serve 30-48 wired devices.
Where the USW-48 Fits
- High-density office floors with 30-48 desktops, printers, and workstations that each need a managed Gigabit port, VLAN segmentation between departments, and fiber uplinks to the core
- Server rooms and lab environments where 48 ports connect physical servers, hypervisors, NAS devices, and test equipment that all have dedicated AC power and only need high-port-count switching
- Split-role deployments where a separate PoE switch handles the 8-16 PoE devices (APs, cameras, phones) and the USW-48 serves the remaining non-PoE devices at a lower cost per port with zero fan noise
What the USW-48 Delivers
- 48x Gigabit RJ45: All ports at 1 Gbps with non-blocking switching across all 48 simultaneously. Enough ports for an entire floor or server room in a single 1U device.
- 4x 1G SFP uplinks: Four fiber slots for core connectivity, redundant uplinks, or LAG aggregation. Supports Gigabit SFP modules (multi-mode or single-mode).
- Fanless, silent operation: Zero acoustic noise from the switch. Suitable for open-plan offices, classrooms, or any location where equipment noise is not acceptable.
- 1.3-inch touch LCM: Front-panel display shows port status, throughput, and device information. Quick diagnostics at the rack without opening the UniFi dashboard.
- Layer 2 managed: 802.1Q VLANs, IGMP snooping, port mirroring, spanning tree, and per-port operating mode. Full configuration and monitoring through UniFi Network.
