D-Link DGS-3630-28PC 28-Port Gigabit Stackable PoE+ Switch

Stackable Power for a Connected Workplace The DGS-3630-28PC combines 20 dedicated Gigabit copper ports with PoE+, four Gigabit copper/SFP combo ports and four 10G SFP+ uplinks. It suits business access and aggregation networks that need clearly planned connections, central administration and room to expand. A 370W shared PoE+ budget powers compatible cameras, access points and phones. Physical stacking links up to nine compatible switches, while VLANs, access controls and entry-level routing support an organised network. Software image and firmware determine the available routing features; advanced capabilities must be specified with the appropriate licence. Highlights Connections and Throughput 20 dedicated Gigabit copper ports with PoE+. 4 × Gigabit copper/SFP combo ports and 4 × 10G SFP+ uplinks. 128 Gbps switching capacity; up to 95.24 Mpps forwarding. Network Control Up to nine switches in a physical stack with up to 80 Gbps stacking bandwidth. VLANs, ACLs, static routing and browser/CLI administration. Standard, Enhanced and MPLS software images provide different feature levels. Power and Installation 370W PoE+ budget; up to 740W with a compatible DPS-700 arrangement. 19-inch 1U rackmount design with smart cooling fans. 5-year warranty. Key Features Connect the Right Mix of Devices 20 dedicated Gigabit copper ports with PoE+ provide the main access connections. Four combo positions add a choice of Gigabit copper or SFP for each logical port. A combo position uses one medium at a time, so the visible alternative connectors do not create extra independently usable ports. Give Aggregated Traffic a 10GbE Path Four SFP+ slots support 10GbE uplinks using separately selected supported optics or direct-attach cables. Plan uplink and stacking assignments together: a port dedicated to a stack connection is no longer an ordinary uplink. Fibre type, cable length and the remote interface must match the chosen module. Expand With a Consistent Stack Up to nine compatible switches can form a physical stack, with up to 80 Gbps stacking bandwidth. Members must use the same software image version and supported firmware. Ring and chain topologies allow a deliberate expansion design; commission and test the complete topology before relying on its resilience. Choose the Software Capability You Need Standard Image covers Layer 2 switching and entry-level routing, including IPv4/IPv6 static routing and RIP. Some additional routing functions depend on firmware. Enhanced Image adds the full advanced Layer 3 feature set, while MPLS Image adds service-provider functions. Required image upgrades are separate licences; specify the routing design before ordering. Control Access and Investigate Problems VLANs separate services, ACLs restrict traffic, and 802.1X with RADIUS helps manage network access. Eight traffic queues per port support prioritisation. Web administration, CLI, SNMP and Ethernet OAM give administrators configuration and diagnostic tools. Apply these controls as part of the complete security design, alongside the upstream firewall. Plan Power Resilience The internal supply provides a 370W shared PoE+ budget. A supported DPS-700 installation can raise the available budget to 740W. The total is shared across powered ports; 30W per-port support does not mean every port can simultaneously deliver its maximum. Size the power arrangement for the intended endpoint load. Summary The DGS-3630-28PC provides Gigabit access, 10GbE uplinks and stackable administration for a structured business network. Specify optics, stacking links, software image and any redundant-power equipment together so the installation matches its traffic and resilience requirements. Frequently Asked Questions How Many Ports Can Be Used at Once?ExpandCollapse There are 20 dedicated access ports, four Gigabit combo ports and four 10G SFP+ slots. Each combo port uses either copper or SFP at a time. Ports allocated to stacking are then occupied by the stack connection. Are Optics and Stacking Cables Included?ExpandCollapse No. Supported transceivers, direct-attach cables and stacking connections are selected separately for the required fibre, speed and distance. Are Advanced Routing Licences Included?ExpandCollapse This base offer does not include a separately purchased Enhanced or MPLS upgrade. Standard Image provides entry-level routing. Full advanced Layer 3 and MPLS functions require the appropriate image; confirm the required protocol and firmware before ordering. Can I Stack Different Software Images?ExpandCollapse No. Physical stack members must run the same image version, with supported firmware and connections. The manufacturer specifies up to nine switches in one physical stack. Does It Supply Power to Endpoints?ExpandCollapse Yes. The 24 Gigabit copper access positions support IEEE 802.3af/at PoE+, with up to 30W per powered port within the 370W shared budget. Combo positions use one medium at a time. What Does the Optional Redundant Supply Provide?ExpandCollapse A compatible DPS-700 can provide backup power and increase the shared PoE budget to 740W in a supported arrangement. The external supply is separate and does not contain a backup battery. 続きを読む
