D-Link DGS-1250-52X 48-Port Gigabit Smart Managed Layer 2+ Switch with 10G SFP+

Bring Dense Gigabit Access onto a 10G Uplink Backbone The D-Link DGS-1250-52X pairs 48 Gigabit RJ45 access ports with four dedicated 10G SFP+ uplinks for a larger office floor or rack with dense Gigabit access and shared upstream traffic. It gives everyday wired devices a familiar copper connection while providing a faster upstream path for the combined traffic heading towards storage, servers or the network core. Smart managed Layer 2 features, static IPv4/IPv6 routing and a full command-line interface give administrators control over segmentation, access and maintenance. With 176 Gbps switching capacity, dual software images and configuration files, it is a practical step up when a Gigabit-only uplink has become the constraint in an otherwise suitable access network. Highlights Access and Uplinks 48 × 10/100/1000BASE-T RJ45 access ports. Four dedicated 10G SFP+ uplink ports, separate from the copper ports. 176 Gbps switching capacity and up to 130.95 Mpps forwarding. Managed Network Control Full CLI, dedicated RJ45 console, web GUI and SNMP. VLANs, eight QoS queues, LACP and STP/RSTP/MSTP. Static IPv4/IPv6 routing, 802.1X, ACLs and dual configurations. Key Features Give Shared Upstream Traffic More Room Four dedicated 10G SFP+ ports provide higher-speed links towards compatible storage, servers or an aggregation switch. The 48 RJ45 ports remain Gigabit access connections, so existing desktops and other endpoints can stay in place. This separates the job of connecting local devices from carrying their combined upstream traffic; select compatible optics or direct-attach media for the equipment and distance involved. Build a Clearer Network with VLANs and QoS 802.1Q VLANs let you separate staff, voice, surveillance and other network roles on shared physical infrastructure. Auto Voice VLAN and Auto Surveillance VLAN support suitable deployments, while eight priority queues and multiple scheduling methods help organise competing traffic. Apply consistent VLAN and QoS policies across the uplink and gateway so that the wider network follows the design established at the switch. Add Resilience Without Losing Visibility STP, RSTP and MSTP support redundant topologies, and LACP can aggregate compatible links for multiple traffic flows. IGMP snooping helps control multicast distribution, while LLDP and port mirroring provide useful visibility during installation and troubleshooting. These tools help keep a busy access layer manageable as more devices and applications are added. Apply Access and Routing Policies at the Edge The switch combines 802.1X authentication, ACLs, IP-MAC-port binding and DHCP safeguards with IPv4/IPv6 static routing. Administrators can define which devices connect and how selected local networks communicate. Four IP interfaces, up to 124 IPv4 routes and 50 IPv6 routes suit straightforward routing requirements; dedicated firewall and internet gateway functions remain the responsibility of the appropriate network equipment. Use the Management Interface That Fits the Job A dedicated RJ45 console provides direct command-line access during deployment and troubleshooting, alongside browser management and SNMP for routine administration. The console is a serial management connection, separate from the Ethernet access ports. D-Link Network Assistant assists discovery, and configuration backup, logs and command logging help maintain a clearer record of the running network. Plan Maintenance and Rack Installation Properly Dual software images and dual configuration files give administrators options when preparing changes or recovering a known configuration. The internal universal AC supply and rackmount chassis simplify equipment-room installation, while active fan cooling requires suitable airflow and allowance for operating noise. Use firmware for the supplied hardware revision and match transceivers, power connections and rack hardware before deployment. Summary The DGS-1250-52X suits a larger office floor or rack with dense Gigabit access and shared upstream traffic when Gigabit endpoints need a stronger upstream connection. Dedicated 10G SFP+ ports, comprehensive traffic controls and full CLI management support a more capable access layer, while static routing and security features provide room for a structured network design. Its access ports remain Gigabit, and this non-PoE model does not power connected devices. Frequently Asked Questions Are All the Ports 10 Gigabit?ExpandCollapse No. The 48 RJ45 access ports support 10/100/1000 Mbps. Four separate SFP+ uplink ports support 10G connections using compatible media. The RJ45 access ports do not support 2.5GbE, 5GbE or 10GBASE-T. Are the SFP+ Ports Shared with the Copper Ports?ExpandCollapse No. The four SFP+ uplinks are dedicated ports, giving 52 network ports in total. The additional RJ45 console socket is for serial management and is not another Ethernet data port. Can This Model Supply PoE Power?ExpandCollapse No. The DGS-1250-52X is the non-PoE version. Cameras, access points and phones that require PoE need a compatible injector or a PoE switch, or their own supported power supply. Can It Route Between VLANs?ExpandCollapse Yes. It supports static IPv4/IPv6 routing with up to four IP interfaces, 124 IPv4 static routes and 50 IPv6 static routes. It also supports VLANs, QoS and ACLs. This does not replace a firewall, internet gateway or dynamic-routing platform where those functions are required. How Can I Configure and Monitor It?ExpandCollapse Use the full CLI through the dedicated serial RJ45 console, the web interface or SNMP. D-Link Network Assistant supports discovery, and dual images, configuration backup and logs assist maintenance. Use firmware and management procedures matched to the supplied hardware revision. Is It Suitable for a Quiet Desk Area?ExpandCollapse This model uses active fan cooling rather than a fanless design. Allow for operating noise and keep airflow clear; an equipment rack or suitable communications space is normally more appropriate than a noise-sensitive desk. The internal supply accepts 100–240 V AC, and hardware warranty coverage is five years. Read more
