Network switch D-Link DGS-1210-52 — 48x 10/100/1000 Mbps RJ45, 4x Gigabit SFP, rack-mountable

The D-Link DGS-1210-52 is a Layer 2 managed Ethernet switch designed for small to medium business networks. It offers 48 Gigabit RJ45 ports that support 10/100/1000 Mbps auto-negotiation and four dedicated Gigabit SFP slots for fiber uplinks. The switch is delivered in a rack-mountable form factor and includes Layer 2 features such as VLAN, QoS and traffic management that allow segmentation, prioritization and efficient use of available bandwidth across wired endpoints and fiber links.

Advantages

The DGS-1210-52 combines high port density with flexible uplink options and centralized traffic control. Its rack-mountable chassis simplifies installation in standard 19-inch racks while the combination of 48 Gigabit RJ45 ports and 4 SFP slots enables both copper connectivity for end devices and fiber-based uplinks to core switches or distribution points. Layer 2 management capabilities, including VLAN tagging and QoS policies, help ensure predictable performance for business applications and support network segmentation and traffic prioritization without requiring complex configuration.

Suitable for

• Wired access layer for office floors or open-plan workspaces
• Aggregation of multiple edge switches to a distribution or core network
• Environments requiring fiber uplinks to data closets or building backbones
• Small to medium-sized IT infrastructures needing VLAN segmentation and QoS

Key specifications

• 48 x 10/100/1000 Mbps RJ45 ports with auto-negotiation
• 4 x Gigabit SFP slots for fiber uplinks
• Layer 2 switching features: VLAN, Link Aggregation, Spanning Tree
• Quality of Service (QoS) and traffic prioritization
• Rack-mountable 19-inch chassis
• Managed switch functionality suitable for access or aggregation roles

How to use

Install the DGS-1210-52 in a standard 19-inch rack and connect power according to the supplied documentation. Use the RJ45 ports to connect desktops, IP phones, wireless access points or other Ethernet devices and populate SFP slots with compatible transceivers for fiber connections to uplink or distribution switches. Configure VLANs, QoS and other Layer 2 settings via the switch’s management interface to segment traffic and prioritize critical services. For multi-switch deployments, enable link aggregation or spanning tree as required to optimize redundancy and throughput.

Usage recommendations

Place the switch in a temperature-controlled, ventilated equipment rack and use proper cable management to maintain airflow. When deploying fiber uplinks, choose SFP transceivers that match the fiber type and distance requirements. Apply VLAN and QoS policies based on application and device classes to maintain predictable performance for voice and business-critical traffic.
