D-Link DGS-3130-30S 30-Port Gigabit SFP Layer 3 Stackable Switch

Bring Fibre Access into a Managed Layer 3 Network The D-Link DGS-3130-30S combines 24 × gigabit sfp access with two 10GBASE-T and 4 10G SFP+ uplinks. It brings switching, dynamic routing and physical stacking into a rackmount platform for business networks that need organised connectivity, clear traffic separation and practical room for expansion. Gigabit SFP access supports suitable fibre links, while separate 10G uplinks connect the switch to faster aggregation equipment. VLANs, access controls and monitoring tools help keep day-to-day administration consistent. Choose the uplink optics, cables and any optional power equipment to suit the installation; published link rates describe interface capability rather than guaranteed application throughput.

They are separate from its four 10G SFP+ uplinks and two 10G copper ports. Match each optic to the link speed, fibre type, wavelength and distance at both ends. Keep Uplink Choices Flexible Two 10GBASE-T ports and 4 10G SFP+ slots let the network combine copper and optical uplinks. Compatible optics or direct-attach cables are selected separately. Interfaces used for physical stacking are part of this same port set, so reserve them when planning the uplink layout. Grow with a Co-ordinated Physical Stack Up to nine 30-port models in a physical stack. Mixed stacks allow up to nine units with a maximum combined stack cost of 12: a 30-port model counts as one and a 54-port model counts as two. Stacking bandwidth is up to 80 Gbps per device and uses 10G interfaces. A stack can simplify administration across multiple units and support a redundant ring design when correctly cabled. Physical stacking is different from virtual management, and the available forwarding and uplink design still need to match the workload. Route Between Network Segments IPv4/IPv6 routing supports static routes, RIP/RIPng and OSPFv2/v3, with policy-based routing and VRRP tools for a suitably designed network. Use these functions to organise traffic between departments, services or VLANs while keeping access policies deliberate. Route-table limits and the upstream firewall or gateway remain part of the overall design. Keep Shared Services Organised VLANs, link aggregation, spanning-tree protocols and Ethernet Ring Protection Switching help structure a resilient Layer 2 network. Eight QoS queues provide traffic-priority controls, while IGMP and MLD snooping help manage multicast distribution. The resulting performance depends on a sound topology and correctly configured endpoints. Make Administration Easier to Maintain A separate out-of-band management port and serial console support administration without consuming the normal data-port count. USB 2.0 supports documented configuration, image and log tasks. Authentication, DHCP snooping, access-control lists and monitoring tools help support consistent operations. Dual images and configuration files provide useful options when planning controlled firmware changes. Summary The DGS-3130-30S brings fibre access, 10G uplinks and Layer 3 management together in a stackable business switch. Its value is in a balanced network design: suitable access links, deliberate segmentation, properly sized uplinks. Select compatible optics and any optional power equipment around the exact deployment. Frequently Asked Questions Which Ports Provide 10-Gigabit Connections?ExpandCollapse Two 10GBASE-T ports and 4 SFP+ slots provide the 10G uplink interfaces. The 24 access ports are Gigabit SFP connections. Console and out-of-band management ports are for administration rather than extra data connections. Does This Switch Supply PoE?ExpandCollapse This is a non-PoE model. It does not supply operating power to access points, cameras or other devices through its data ports. Use an appropriate PoE switch or injector where the connected equipment requires power. How Many Switches Can Be Stacked?ExpandCollapse Up to nine 30-port models in a physical stack. Mixed stacks allow up to nine units with a maximum combined stack cost of 12: a 30-port model counts as one and a 54-port model counts as two. Stacking bandwidth is up to 80 Gbps per device and uses 10G interfaces. Are SFP Modules and Stacking Cables Included?ExpandCollapse Select compatible optical modules or direct-attach cables separately for the intended link. Match the transceiver standard, fibre type, reach and switch compatibility. Where a 10G interface is used for stacking, include that allocation in the port plan. Can the Switch Route Between VLANs?ExpandCollapse Yes. The documented Layer 3 functions include IPv4/IPv6 static routing, RIP/RIPng and OSPFv2/v3, alongside VLAN segmentation and access controls. It is a managed switch rather than a complete substitute for the internet gateway, firewall or security services. IPv4 PIM-SM multicast routing is documented for standalone operation only. What Should Be Checked Before Installation?ExpandCollapse Confirm the rack space, ventilation, mains supply, uplink media. Dimensions, bare-device weight and power figures vary by hardware revision; confirm the supplied unit when planning a tight rack or power installation. The warranty is 5 years. Optional backup-power equipment and optics require their own exact compatibility check. 더 보기
