With a power consumption of 460W and an integrated power supply, the switch ensures stable voltage delivery to all connected devices. The modular design includes uplink ports for cascading to other network devices, allowing seamless expansion of local area networks.
This section brings together practical product details such as Total Number of Network Ports, Uplink Port, Modular, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages
Layer 4 management capabilities enable advanced traffic control, including quality of service (QoS) policies and bandwidth limiting, which are essential for maintaining network performance in shared or congested environments.
These strengths make the product easier to deploy and manage in real environments, especially where reliability, usability, and day-to-day operational continuity matter. Notable benefits include High-Density PoE+, Scalable Uplinks.
High-Density PoE+
The 370W PoE budget distributes power across 48 ports, eliminating the need for separate power injectors and simplifying deployments for VoIP, wireless, and IoT devices.
Scalable Uplinks
Four 10G SFP+ slots provide flexible uplink options for high-bandwidth aggregation, backbone connections, or future network growth without replacing the switch.
Deployment / Use Cases
The switch's rack-mountable 1U form factor fits standard server cabinets, making it a practical choice for data centers, network closets, or any environment where space optimization is critical. Its support for optical fiber uplinks allows spanning longer distances between buildings or floors while maintaining high data transmission rates.

Office and Campus Networks
Ideal for connecting workstations, printers, and IP phones in medium to large offices, with PoE+ support for wireless access points and security cameras.
Multi-Tenant Environments
Suitable for shared office spaces or retail centers where bandwidth limiting and traffic isolation between tenants are required for fair usage and security.
Physical Profile
The switch features a compact 1U rack-mountable design with dimensions of 1.73" (43.94 mm) height, 17.42" (442.47 mm) width, and 12.70" (322.58 mm) depth. Weighing approximately 9.97 lb (4522.32 g), it is lightweight yet durable for professional installations. Rack mounting facilitates organized cable management and secure placement in server rooms or network racks.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.73" (43.94 mm), 17.42" (442.47 mm), 12.70" (322.58 mm), 9.97 lb (4522.32 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
