Ubiquiti USW-48 | UniFi Switch 48 | 52 Gbps Switch

A fanless 48-port gigabit switch for server rooms and comms cabinets where silence matters and port density is the priority.

Why this one

• Completely fanless cooling keeps the switch silent at 40W draw — useful in a comms cabinet adjacent to a workspace where fan noise carries.
• 52 Gbps non-blocking throughput across 48 gigabit ports means no port contention even when the whole switch is fully loaded at once.
• Support for 1,000 VLANs and a 16,000-entry MAC address table gives you enough headroom to segment a sizeable network without hitting software limits.
• Four 1G SFP uplink ports let you connect to an aggregation switch or a fibre run without occupying any of the 48 copper ports.

Good fit if you're building out a UniFi network and need a high-density access layer switch in a 1U rack slot, and none of your connected devices require PoE power from the switch itself.

Worth considering something else if you need to power cameras, access points or phones directly from the switch — the USW-48-POE carries the same port count with PoE budget built in, so you won't need separate injectors at every device.

What you'll also need

A UniFi gateway or controller running UniFi Network 7.2.94 or later, rack space with at least 400mm depth, and — if you're powering any access points or cameras from this switch — either a USW-48-POE instead or separate PoE injectors for those devices.
