Switch Ubiquiti UniFi USW-48 network switch Managed L2 Gigabit Ethernet (10/100/1000) Silver

The Ubiquiti UniFi USW-48 is a 1U, 48-port managed L2 Gigabit switch, aimed at small and medium offices, larger home networks, and locations with many end devices. All ports are Gigabit Ethernet (10/100/1000 Mbps), which gives you sufficient throughput for modern workstations, IP phones, and media devices. The device is fanless with passive cooling, so it operates silently and is suitable for installation in an office or even a room at home. It is centrally managed via the UniFi Network Controller and the UniFi Network mobile app, which facilitates configuration and monitoring.

What you get

You get 48 x RJ-45 ports with support for 10/100/1000 Mbps, which is enough to connect an entire floor installation or a larger office to a single centralized point. The LAN architecture is Gigabit Ethernet, so communication between servers, workstations, and NAS devices will run smoothly without being bottlenecked by 100 Mbps limitations. As a managed L2 switch with support for protocols such as DHCP Snooping, IGMP Snooping, LLDP-MED, and Voice VLAN, the switch gives you control over traffic, prioritization for voice (VoIP), and protection against rogue DHCP devices. The built-in AC/DC power supply 60W (100–240 VAC, 50/60 Hz) eliminates the need for external adapters and makes the installation cleaner and safer in a standard 19" rack. The 1.5 MB buffer memory helps with smoother handling of burst traffic, typical for file transfers and backups.

• 48 x RJ-45 Gigabit ports (10/100/1000 Mbps) allow you to connect a large number of devices – from PCs and printers to IP phones and media players – in a single common network.
• Layer 2 managed switch functionality provides the ability for VLAN segmentation, finer traffic control, and better security compared to a regular unmanaged switch.
• Fanless, silent cooling means completely silent operation, which is ideal for office spaces, conference rooms, or home server corners without a separate noisy rack room.
• Management via UniFi Network Controller and UniFi Network mobile app facilitates centralized configuration, updates, and monitoring of all UniFi devices in your network.
• Support for IPv4, DHCP Snooping, IGMP Snooping, LLDP-MED, and Voice VLAN helps you protect the network from unwanted DHCP sources, optimize multicast traffic, and ensure higher-quality VoIP telephony.
• Gigabit Ethernet LAN architecture provides sufficient capacity for file servers, cloud services, and working with heavier applications on the local network.
• Built-in AC/DC power supply 60W (100–240 VAC, 50/60 Hz) makes the device ready for direct installation in standard infrastructure, without the need for external adapters and additional cable clutter.
• 1U form factor makes it easy to integrate into standard rack cabinets, taking up minimal space relative to the number of ports it offers.

Who it is suitable for

This switch is suitable if you are building or expanding an office network, co-working space, small business infrastructure, or a more serious home LAN with many devices. It is also suitable for environments with VoIP telephony and IP TV, where features like IGMP Snooping and Voice VLAN matter. If you rely on PoE for powering cameras or access points, keep in mind that this model does not have PoE, and you will need a separate PoE switch or injectors.

The combination of 48 Gigabit ports, L2 manageability, silent passive cooling, and integration with the UniFi ecosystem makes the Ubiquiti UniFi USW-48 a very stable foundation for a serious, yet still organized and quiet network infrastructure.
