💼 48-Port Gigabit Smart Switch for SMB and Professional Networks

📋 Complete Technical Specifications

🎯 Strengths of the D-Link DGS-1248T

• 48 High-Density Gigabit Ports - Abundant connectivity of 10/100/1000 Mbps for workstations, network printers, departmental servers, IP surveillance cameras, and WiFi access points with auto-negotiation of duplex speed optimizing performance automatically based on connected equipment.
• Smart Switch Web Management - Intuitive HTTP/HTTPS graphical administration interface accessible via browser without proprietary software, allowing VLAN configuration, QoS, trunking, port security, and performance monitoring by network administrators without complex CLI command line expertise.
• VLANs Network Segmentation - Supports 256 simultaneous VLANs with 802.1Q tagging isolating departments, segmenting voice, data, and video traffic, and creating separate secure guest WiFi networks for production infrastructure to comply with GDPR security.
• Intelligent QoS Prioritization - 4 priority queues per port with 802.1p CoS and DSCP classification ensuring bandwidth for critical applications such as VoIP telephony, HD video conferencing, and cloud SaaS services without latency impacting communication quality.
• 4 Flexible Combo SFP Ports - Mini GBIC/SFP fiber optic uplinks allowing long-distance multimode SX (550m) or single-mode LX (10km) connections to the network core, inter-building campus links, or datacenter connections without the distance limitations of Cat5e/Cat6 copper.
• Multilayer Security - 802.1X RADIUS authentication for granular network access control by user, MAC address limitation port security preventing unauthorized connections, and Access Control Lists (ACL) filtering traffic based on defined IP/MAC address criteria.
• Trunking and Redundancy - LACP link aggregation combining multiple physical ports to increase aggregated bandwidth and fault tolerance, spanning-tree protocols STP/RSTP eliminating network loops in high availability redundant topologies.
• Energy Efficiency - Optimized consumption of 65W maximum compared to similar competing switches, D-Link Green energy-saving technologies automatically disabling unused ports and adjusting power according to detected cable lengths, reducing electricity costs in datacenters.

🔍 Professional Applications and Uses

The D-Link DGS-1248T Smart Switch is perfectly suited for multiple professional environments: access switch for patch cabinets in corporate offices connecting user workstations, multifunction printers, and centralized IP phones, SME infrastructure requiring VLAN management for Accounting/HR/Production departments with secure isolation preventing inter-department communications, university campus networks in computer rooms and libraries connecting hundreds of student stations with access control via RADIUS authentication, hotels and hospitality establishments with connected rooms featuring strict separation between guest WiFi networks and secure management administration networks, retail stores with point of sale terminals, barcode readers, and centralized IP video surveillance systems, small datacenters hosting virtual servers requiring VLAN segmentation for isolated clients ensuring confidentiality, integration of VoIP systems Asterisk/3CX for business telephony with prioritized QoS ensuring audio quality for phone conversations, or IP video surveillance infrastructures managing 40+ megapixel H.264 cameras with dedicated VLANs separating video streams from business data traffic. An ideal solution also for computer labs for technical training, industrial environments connecting Modbus TCP/IP programmable controllers, or temporary event networks for seminars and conferences requiring fast connectivity and simple deployment.
