The Ubiquiti Standard 48 PoE (USW-48-POE) is a managed Layer 2 rackmount switch with 48 Gigabit Ethernet ports, including 32 PoE/PoE+ ports, and four 1G SFP uplinks. Its 195W PoE budget and fanless cooling suit offices or small and midsize networks connecting access points, cameras, and wired devices.
Recommended For
- Small-business or office network operators wiring many desks, printers, and other Ethernet devices who want a managed, rack-mounted 48-port switch with VLAN and traffic-management features.
- Installers building a wired UniFi camera and access-point network who need PoE+ on selected ports and can plan the connected devices around the switch’s 195W total PoE budget.
- Home-lab or small-office builders who need a large number of wired Gigabit ports and prefer silent, fanless cooling for a rack near a workspace.
- Network administrators already using UniFi Network who want to manage a large Layer 2 access switch alongside their UniFi devices.
Real-World Use Scenarios
- In a larger home or small office with many wired devices, use the USW-48-POE as a central rack switch for computers, printers, access points, and cameras; its 48 Ethernet ports can reduce the need for multiple small edge switches, while UniFi management keeps the ports visible in one interface.
- For a UniFi camera-and-Wi-Fi installation, connect compatible access points and cameras directly to the switch so each endpoint can receive data and PoE over its Ethernet cable; check the device requirements and shared 195 W PoE budget before expanding the system.
- In a small business with desk phones, Wi-Fi access points, and other wired equipment, use the managed switch to bring those connections together and apply supported settings such as voice VLANs; the network gateway still handles routing between VLANs.
- When a camera system grows, dedicate switch ports to the cameras and monitor their link and PoE status from the managed network; the 195 W total PoE budget means the supported camera count depends on each camera’s power draw, not just the number of ports.
- For a wiring closet connected to a router or another switch, use an SFP port for a compatible fiber uplink; this provides a separate link between network areas, with the uplink operating at up to 1 Gbps.
