D-Link DXS-3400-24SC 24-Port 10G Fibre Stackable Managed Switch

Dense 10GbE Connectivity for a Planned Network Core The DXS-3400-24SC provides 20 dedicated 10G SFP+ ports and four 10GBASE-T/SFP+ combo positions. It suits business aggregation and distribution designs that need managed connections, traffic separation and a defined path to expand. Choose Standard Image or Enhanced Image under Edition to match the required routing functions. Physical stacking, traffic controls and modular cooling and power support a carefully designed top-of-rack or aggregation deployment. Select optical modules, stacking links and the required routing functions for the actual network; visible connector counts and software capabilities must be interpreted together. Highlights Connections and Performance 20 × 10G SFP+ dedicated ports. 4 × 10GBASE-T/SFP+ combo positions; one medium per position. 480 Gbps switching capacity; up to 357.12 Mpps forwarding. Network Control VLANs, link aggregation, access controls and traffic prioritisation. Physical stacking with supported firmware and cabling. Choice of Standard Image or Enhanced Image software configuration. Installation 19-inch rackmount design. Supported redundant power option purchased separately. Non-PoE data ports; optics and stacking cables selected separately. Key Features Match the Ports to the Access Network Twenty dedicated 10G SFP+ ports provide the main connections. Four combo positions each offer either 10GBASE-T copper or SFP+ optical connectivity. A combo position is one logical port, so its alternative connectors cannot both operate as independent ports. Choose compatible optics and cabling for the remote interface, required speed and fibre distance. Plan Uplinks and Stacking Together Four 10G ports can provide a physical stack of up to four compatible switches with up to 80 Gbps stacking bandwidth. A port assigned to stacking is then occupied by that connection. Use supported cable types and matched firmware, and validate the full ring or chain topology. Keep Routing Requirements Explicit Standard Image provides managed Layer 2 functions and its documented entry-level routing capabilities. Enhanced Image includes the additional supported Layer 3 functions, including OSPF, BFD and multicast routing. Select the required Edition before ordering; a Standard Image unit needs the appropriate separate upgrade licence to gain Enhanced Image functions. Design the upstream firewall and routing policy as part of the complete installation. Control Access and Prioritise Services VLANs organise services and users, while access-control lists, authentication and DHCP/ARP protection functions support a controlled network. Quality of Service gives important traffic appropriate prioritisation. These controls require a deliberate configuration and do not replace endpoint security, a perimeter firewall or monitoring. Provide a Maintainable Power Arrangement The normal configuration includes one hot-swappable 300 W AC supply and three front-to-back fan modules. A separately purchased compatible second supply enables the supported redundant power arrangement. Fan and power modules are serviceable without treating the switch as a sealed desktop device. Redundant power is separate from battery backup, so use an appropriate UPS where loss of mains power must be addressed. Make Administration Part of the Design Web management, CLI, SNMP and event information support configuration and fault investigation. Dedicated management and console connections allow a defined administration path separate from ordinary traffic. Restrict management access, retain configuration backups and stage firmware changes so the network remains maintainable after installation. Summary The DXS-3400-24SC is a structured choice for dense 10GbE aggregation when port planning, central administration and expansion matter. Specify the optical links, stack topology, software functions and power arrangement together, then test the complete configuration against the network’s traffic and availability requirements. Frequently Asked Questions Are All Visible Connectors Independent Ports?ExpandCollapse No. There are 20 dedicated ports and four combo positions. Each combo position uses either its copper connector or its SFP+ slot at a time, for 24 logical ports in total. Are Optical Modules and Stack Cables Included?ExpandCollapse No. Select supported transceivers or direct-attach cables separately for the remote interface, fibre type, speed and distance. Stack connections also need the appropriate supported cabling. Does It Supply PoE Power?ExpandCollapse No. This is a non-PoE data switch. Cameras, access points and other powered devices need a suitable separate power source or an appropriate PoE switch/injector. Which Routing Software Is Included?ExpandCollapse The selected Edition determines the software supplied. Standard Image supplies the base feature set; Enhanced Image includes the supported advanced Layer 3 entitlement. A Standard Image order does not include an Enhanced Image upgrade licence. How Many Switches Can Be Stacked?ExpandCollapse Up to four compatible switches in a physical stack, with up to 80 Gbps stacking bandwidth. Stack cabling and matched supported software are required separately. Does Redundant Power Replace a UPS?ExpandCollapse No. An optional compatible redundant supply helps address a supply failure. It does not provide battery runtime during loss of all AC power sources; a suitable UPS remains separate. 阅读更多
