Product Features
Technical Overview
The USW-48 operates as a Layer 2 switch, supporting essential networking protocols such as IGMP snooping, port mirroring, and spanning tree for optimized traffic management and network stability. It leverages Gigabit Ethernet technology across all ports, ensuring high-speed data transfer with support for 1000Base-T over twisted pair and 1000Base-X over optical fiber.
The switch includes 4 SFP (mini-GBIC) expansion slots, providing flexibility for fiber uplinks or long-distance copper connections. While it does not offer Power over Ethernet (PoE) on its RJ-45 ports, its focus remains on pure data switching with reliable performance and environmental compliance under the Waste Electrical and Electronic Equipment (WEEE) Directive.
Relevant factors for this section include Total Number of Network Ports, Modular, Port/Expansion Slot Details, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

FAQ
How many devices can I connect to the Ubiquiti USW-48 switch?
The USW-48 provides 48 Gigabit Ethernet ports, allowing direct connections for up to 48 wired devices such as computers, printers, or access points. Additionally, the 4 SFP slots can be used for uplinks, expanding network capacity without consuming Ethernet ports.
Does this switch support Power over Ethernet (PoE)?
No, the USW-48 does not include PoE on its RJ-45 ports. It is designed as a data-only switch, making it suitable for deployments where PoE is provided by separate switches or injectors, ensuring dedicated power management and switching efficiency.
What are the SFP slots used for on this switch?
The 4 SFP (mini-GBIC) slots enable fiber or copper uplink connections. You can insert compatible SFP modules to connect to other switches, routers, or network segments over longer distances, supporting both 1000Base-X for fiber and extended copper runs.
Is the Ubiquiti USW-48 a managed switch?
Yes, it is a fully manageable Layer 2 switch. It can be configured and monitored through the UniFi Controller software, offering features like VLANs, QoS, port security, and traffic analysis for optimized network performance and control.
What networking layer does this switch operate at?
The USW-48 operates at Layer 2 of the OSI model. This means it handles switching based on MAC addresses, supporting essential protocols for efficient local network traffic, such as spanning tree for loop prevention and IGMP snooping for multicast optimization.
What warranty comes with the Ubiquiti USW-48 switch?
Ubiquiti provides a 2-year limited warranty for the USW-48, covering defects in materials and workmanship. The switch is also environmentally compliant with the WEEE Directive, ensuring responsible disposal and recycling practices.
