Product Features
Technical Overview
This switch operates at Gigabit Ethernet speeds across all ports, supporting both 1000Base-T over twisted pair and 1000Base-X over optical fiber. The four expansion slots are dedicated SFP (mini-GBIC) ports, not shared with the copper ports, providing independent uplink capacity without compromising PoE availability.
The integrated power supply delivers a 740W PoE budget, allowing administrators to power numerous devices simultaneously while maintaining headroom for future expansion. Layer 3 support enables advanced routing protocols, VLAN routing, and policy-based routing for efficient traffic management in complex network topologies.
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.

FAQ
How many devices can this switch power with PoE?
The switch has a 740W PoE budget and 48 PoE+ ports. The actual number of devices depends on each device's power draw. For example, it could power around 48 standard VoIP phones (typically 7-15W each) or a mix of higher-power devices like wireless access points and cameras. The 740W budget provides substantial headroom for dense PoE deployments.
What are the SFP slots used for?
The four SFP (Small Form-factor Pluggable) slots are uplink ports that accept SFP transceiver modules. You can use them to connect the switch to other network equipment via fiber optic cables for long-distance links or high-speed copper connections. They are dedicated slots, not shared with the copper ports, ensuring uplink capacity is always available.
Does this switch support Layer 3 routing?
Yes, this is a Layer 3 switch. It supports advanced routing functions such as static routing, RIP, OSPF, and inter-VLAN routing. This allows it to route traffic between different subnets or VLANs without needing a separate router, improving network efficiency and scalability in complex environments.
What is the form factor and rack compatibility?
The switch has a 1U rack-mountable form factor, meaning it occupies one rack unit of space in a standard 19-inch rack. Its dimensions are 1.73" height, 17.42" width, and 12.76" depth. This compact design makes it easy to install in data centers, network closets, or server rooms while optimizing rack space.
Is this a managed or unmanaged switch?
This is a fully managed switch. It offers comprehensive management features including VLAN configuration, QoS, security policies, SNMP monitoring, and web or CLI-based administration. Managed switches provide greater control, visibility, and reliability for business networks compared to unmanaged switches.
What types of cables and media does this switch support?
The switch supports both twisted pair (copper) and optical fiber media. The 48 Gigabit Ethernet ports use standard RJ-45 connectors for Cat5e/Cat6/Cat6a copper cables. The four SFP slots accept SFP modules for fiber optic cables (like LC connectors) or copper SFP modules for additional twisted pair connections, offering flexibility for different network segments.
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.
