Deployment / Use Cases
This switch is ideal for deployment in medium to large office environments, educational campuses, or hospitality venues where a high number of wired connections and powered devices are concentrated. Its Layer 3 capabilities make it suitable for segmenting network traffic between departments, VLANs, or guest networks while maintaining performance.
The four SFP+ uplink ports enable high-speed aggregation to core switches or connections to servers and network-attached storage, supporting data-intensive tasks like video editing, virtualization, or centralized backups. The rack-mount design ensures it integrates seamlessly into existing server room or network closet infrastructure.
Unified Network Backbone
Acts as an access layer switch in a hierarchical network design, connecting end-user devices and providing PoE to edge devices while uplinking to distribution or core switches at 10GbE speeds.
High-Density Device Support
Efficiently powers and connects large clusters of IP phones, security cameras, and wireless access points in a single rack unit, reducing physical footprint and simplifying management.
Physical Profile
Constructed from durable steel, the switch measures 1.73 inches in height, 17.40 inches in width, and 15.75 inches in depth, fitting standard 19-inch rack enclosures. Its 1U height optimizes rack space utilization, while the weight of approximately 13.67 pounds reflects a solid build quality suitable for continuous operation in controlled environments.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.73" (44 mm), 17.40" (442 mm), 15.75" (400 mm), 13.67 lb (6200 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
What is the total PoE budget of this switch?
The Ubiquiti Switch Enterprise 48 PoE provides a total PoE budget of 720 watts. This budget is shared across all 48 PoE+ ports, allowing the switch to power a combination of devices such as wireless access points, IP cameras, and VoIP phones without requiring external power injectors. The budget supports IEEE 802.3af and IEEE 802.3at standards, ensuring compatibility with a wide range of powered devices.
How many SFP+ uplink ports are available?
This switch includes four SFP+ expansion slots dedicated to uplink connections. These slots support 10 Gigabit Ethernet via optical fiber or copper SFP+ modules, enabling high-speed backbone links to other switches, servers, or network storage. The uplink ports are modular, allowing network administrators to choose the appropriate media type based on distance, cost, and performance requirements.
Does this switch support Layer 3 switching?
Yes, the Switch Enterprise 48 PoE operates at Layer 3, providing routing capabilities between VLANs, IP subnets, and network segments. This allows for advanced traffic management, improved security through access control lists, and reduced reliance on external routers for internal network routing. Layer 3 support enhances performance in segmented network environments typical of enterprise deployments.
What types of cables are supported?
The switch supports both optical fiber and twisted pair cabling. The 48 RJ-45 ports use twisted pair cables (e.g., Cat5e, Cat6, Cat6a) for distances up to 100 meters. The four SFP+ slots can accommodate fiber optic cables for longer distances or copper SFP+ modules for shorter runs, offering flexibility in network design and infrastructure choices.
Is this switch rack-mountable?
Yes, the switch is designed for standard 19-inch rack mounting with a height of 1.73 inches (1U). Its steel chassis includes mounting brackets for secure installation in server racks or network cabinets. The compact 1U form factor maximizes port density per rack unit, making it suitable for space-constrained environments like data centers or network closets.
What are the power input options?
The switch accepts input voltages of 120V AC, 230V AC, 11.5V DC, and 52V DC, providing compatibility with various power sources worldwide. It uses an AC/DC power source with PoE+ support, drawing approximately 150 watts under typical operation.
