Product Features
Technical Overview
This switch operates as a full Layer 3 managed device, supporting advanced routing protocols and features for segmented network design, improved traffic management, and enhanced security policies. The 48 downlink ports are all Gigabit Ethernet with IEEE 802.3at/af PoE+ capability, allowing for flexible device deployment without separate power supplies. The four SFP+ expansion slots support 10 Gigabit Ethernet connections using either optical fiber or direct-attach copper cables, providing high-bandwidth uplinks to core switches or servers.
The integrated power supply delivers a total PoE budget of 740 watts, intelligently allocated across ports to maximize connected device support. With a typical power draw of 49.90 watts for the switch itself, it offers energy-efficient operation. Comprehensive networking standards compliance includes IEEE 802.1Q for VLANs, 802.1x for port-based authentication, 802.3ad for link aggregation, and 802.3az for energy-efficient Ethernet, ensuring interoperability and robust network performance.

Deployment / Use Cases
This switch is engineered for environments where reliable, high-capacity switching and centralized power delivery are non-negotiable. Its blend of port count, PoE budget, and uplink speed suits it for core aggregation in mid-sized networks or as an access layer switch in larger enterprise deployments.
In office buildings or campuses, it can serve as the primary switch for a floor, connecting and powering dozens of workstations, VoIP phones, and wireless access points while linking back to the core via high-speed fiber uplinks. For retail or hospitality venues, it supports extensive IP surveillance systems and point-of-sale networks, with the management features needed to keep traffic segmented and secure. Its 1U rack profile also makes it a fit for data center edge deployments or service provider cabinets where space is at a premium but performance cannot be compromised.
Physical Profile
The switch is built for standard 19-inch rack installation with a 1U (1.73-inch) height, minimizing rack space consumption. Its dimensions of 17.42" wide by 12.77" deep provide a compact footprint, while the approximate weight of 10.56 lb ensures manageable installation. The rack-mountable design includes front-to-back airflow for efficient cooling in enclosed cabinets. All ports and status indicators are front-accessible for easy monitoring and cable management, supporting a clean, professional installation in data centers or wiring closets.

User Manual
FAQ
How many devices can this switch power with PoE+?
The switch has a total PoE budget of 740 watts distributed across its 48 Gigabit Ethernet ports. The exact number of devices depends on the power requirements of each connected device (e.g., an IP phone may use under 10W, while a high-end wireless access point could use 30W or more). The switch intelligently allocates power and can support a full mix of PoE and PoE+ devices up to the 740W limit.
What are the SFP+ uplinks used for?
The four SFP+ uplink ports provide 10 Gigabit Ethernet connectivity, which is typically used to connect this access switch to a core switch, router, or server stack. This high-speed link prevents bottlenecks when aggregating traffic from the 48 Gigabit downlink ports. You can use compatible SFP+ transceivers for fiber optic connections over longer distances or direct-attach copper cables for shorter, cost-effective links within a rack.
What does Layer 3 managed switching mean?
Layer 3 managed switching means the switch can perform basic routing functions between VLANs (Virtual Local Area Networks) at wire speed. This allows for network segmentation, improved traffic management, and the implementation of access control lists (ACLs) for security—all without needing a separate router for inter-VLAN traffic. It provides greater control and efficiency in medium to large network environments compared to simpler Layer 2 switches.
Is this switch rack-mountable?
Yes, this switch is designed for standard 19-inch rack installation and occupies 1 rack unit (1U) of vertical space, which is approximately 1.73 inches tall. It includes the necessary mounting brackets and supports front-to-back airflow for proper cooling in enclosed cabinets. Its compact dimensions make it suitable for data centers, network closets, or any professional rack environment.
What kind of cables can I use with this switch?
The 48 RJ-45 ports support twisted-pair copper cables (Cat5e, Cat6, or higher) for distances up to 100 meters. The four SFP+ uplink ports support optical fiber cables (using SFP+ transceivers) for longer distances or high-speed direct-attach copper cables for short-range connections within a rack. The switch is compatible with both media types, offering flexibility in network design.
How is this switch managed?
This is a fully managed switch, offering multiple management options including a command-line interface (CLI) for advanced configuration, a web-based graphical interface for easier setup and monitoring, and support for SNMP (Simple Network Management Protocol) for integration with network management systems. It also supports features like sFlow for traffic analysis and RMON for network monitoring, providing comprehensive oversight and control.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Yes, giving buyers a clearer picture of expected coverage after purchase.
Does the product support PoE or wireless networking?
Connectivity support is listed in the product specifications, including the relevant wireless or port options when available.
