All 48 RJ-45 ports run at up to 1 Gbit/s and also accept 10 and 100 Mbit/s devices. That covers office computers, printers, IP phones with their own power supply and the rest of the equipment at each desk. Four 1 Gbit/s SFP slots are meant for links to the router, a core switch or another switch, over fibre if the distance between switches is longer than copper cable allows.
According to the manufacturer, the USW-48 has no fan and is cooled passively. No noise comes from the cabinet and no dust is pulled into the device, which helps in less clean rooms as well. The rated operating range is −15 to 40 °C at 10–90 % humidity, so it also copes with a cool equipment room. Maximum power consumption is just 40 W.
The USW-48 is a managed Layer 2 switch: almost all of its features can be configured and monitored in the graphical interface of the UniFi Network controller and mobile app, remotely as well. The manufacturer notes that UniFi Network controller version 5.13.10 or later is required. The firmware is upgradeable, so new features and fixes arrive with software updates.
The front panel has a 1.3-inch touchscreen that supports the UniFi Network augmented reality (AR) feature for managing the switch from a smartphone. A quick status overview is also available without the app, right at the cabinet. LEDs show port and system status, which helps track down cabling problems quickly.
The housing is steel, measures 442.4 × 285 × 43.7 mm and weighs 3.9 kg, and the switch mounts in a server cabinet or rack. The power supply is built in and runs on 100–240 V AC at 50–60 Hz, so there is no separate adapter in the cabinet. The device carries CE, FCC and IC certifications. As an access layer switch it connects desks and devices and passes their traffic on to the network core through the SFP slots.
Offices and schools with many wired workstations and printers, where PoE devices are powered from a separate switch; UniFi network owners who need 48 ports in the same management view; and building or floor distribution cabinets where it matters that the switch runs quietly and draws little power.
