DGS-1248T Overview
The Web Smart DGS-1248T blends plug & play simplicity with exceptional performance and feature sets. With forty-eight 10/100/1000BASE-T ports and four combo SFP expansion slots, the DGS-1248T is designed to help provide a simple and economical migration path from 10BASE-T or 100BASE-TX to 1000BASE-T Gigabit. With 96Gbps in aggregated bandwidth, the DGS-1248T is the ideal solution as a line aggregator for server farms or bandwidth-starved workgroups requiring basic network management functions for today’s diverse multimedia requirements.
Operational Simplicity with Web Smart Features
Management
Managing the DGS-1248T is easy. Using its built in browser-based management interface, configuring the DGS-1248T takes only minutes. With full color graphic pictures, diagrams and easy to understand navigation menus, configuring the DGS-1248T with the features you require is as easy as surfing the net. The DGS-1248T supports many of today’s most sought after features like: priority queing, 802.1Q VLANs, port trunking, port status monitoring, port mirroring, and many others.
Auto-Discovery
The guess work is over. Every DGS-1248T also comes with auto-discovery software that automatically detects and displays up to 254 D-Link Web Smart switches running on your network.
Automatic Port configuration
The DGS-1248T is truly plug-and-play. All RJ-45 ports support auto MDI/MDIX, so there is no longer a need to use cross-over cables or an up-link port. The auto-MDI/MDIX feature will automatically detect whether the switch is connected to another switch or an end-station device and configure the port accordingly. If the DGS-1248T detects a switch connected to one of its ports, it will automatically configure that port to act as an uplink. If the DGS-1248T detects a computer or end station device, the port auto-configures to a standard port. The confusion over cross-over cabling is a thing of the past.
Investment Protection
The DGS-1248T helps to protect customers’ existing and future network infrastructure investments by providing optional gigabit fiber uplinks. With 4 SFP ports, the DGS-1248T can be connected to a distant network or backbone up to 80Km away (SFP transceivers sold separately). The DGS-1248T is the best choice for future proofing your network and is a worthy investment.

Frequently Asked Questions
What are the primary port configurations available on the D-Link DGS-1248T? +
The DGS-1248T features 48 high-speed 10/100/1000BASE-T Gigabit Ethernet ports for copper connectivity. Additionally, it includes 4 combo SFP slots, providing flexible fiber-optic uplink options for connecting to core switches or servers over longer distances without sacrificing your primary copper ports.
How does the Web Smart management interface benefit network administrators? +
The Web Smart interface provides an intuitive browser-based management tool that simplifies network configuration. It allows administrators to easily manage traffic prioritization, virtual LANs (VLANs), and port trunking without the complexity of a full Command Line Interface, making it an ideal solution for businesses needing essential control and visibility.
Does the DGS-1248T support link aggregation for increased bandwidth? +
Yes, this switch supports Link Aggregation, which allows you to combine multiple ports into a single high-bandwidth trunk. This is particularly useful for server-to-switch connections or building high-speed backbones between switches, effectively increasing throughput and providing redundancy to handle high-traffic network environments.
What security features are included in the DGS-1248T to protect my network? +
To ensure network integrity, the DGS-1248T includes essential security features such as MAC address filtering and Access Control Lists (ACLs). These tools help you restrict unauthorized access to your internal network, ensuring that only trusted devices can communicate across your infrastructure while preventing potential bottlenecks or security breaches.
Is the D-Link DGS-1248T suitable for a rack-mounted server room deployment? +
The DGS-1248T is specifically designed for standard 19-inch rack-mount installation. Its 1U form factor makes it a space-efficient choice for server rooms or wiring closets, allowing for neat and organized cable management alongside your existing enterprise rack hardware.
How does the switch handle traffic prioritization for VoIP or video conferencing? +
This switch supports Quality of Service (QoS) features, which allow you to prioritize time-sensitive traffic. By configuring QoS, you ensure that critical data packets—such as those used for VoIP calls or real-time video streaming—are processed ahead of lower-priority background traffic, preventing jitter and ensuring a smooth user experience.
What is the primary advantage of the combo SFP ports on this model? +
The combo SFP ports offer modular flexibility. You can choose to use either the copper port or the SFP slot for each combo pair, allowing for a seamless transition to fiber-optic cabling. This versatility is essential when you need to extend your network reach beyond the 100-meter limitation of standard copper Ethernet.
Can the DGS-1248T manage VLANs to segment department traffic? +
Yes, the switch supports 802.1Q VLAN tagging, which is vital for network segmentation. By creating separate VLANs, you can logically isolate traffic between different departments or guest networks, which significantly enhances security and performance by reducing unnecessary broadcast traffic across your entire local network infrastructure.
