D-Link DGS-1530-20 20-Port Gigabit Stackable Managed Switch

A Quiet Gigabit Access Layer with 10GbE Growth The DGS-1530-20 brings 16 Gigabit access ports and four 10GbE SFP+ uplinks into a managed access layer for offices, education and campus networks. Physical stacking, VLANs, static routing and practical diagnostic tools help a growing network stay organised without treating every switch as an isolated installation.

Select supported optics or direct-attach cables for the actual link distance. These are data-only ports; choose a separate PoE switch or injector for powered endpoints. Scale Through Physical Stacking Combine up to nine compatible switches into a physical stack over suitable 10GbE links. A single management IP simplifies administration while ring or chain topologies provide deployment flexibility. Stacking uses the available uplink ports and requires compatible cables or optics; it is not an additional dedicated uplink connection. Segment the Network and Route Deliberately 802.1Q VLANs, voice VLAN, link aggregation and multicast controls organise traffic across business departments and applications. Lite Layer 3 static routing adds a controlled way to connect IP networks. It does not replace the full dynamic-routing or security feature set of an enterprise router or firewall. Keep Traffic and Access Under Control QoS classification and scheduling help prioritise time-sensitive applications. IEEE 802.1X, RADIUS/TACACS+ support, ACLs, DHCP snooping, ARP spoofing prevention and D-Link Safeguard Engine provide tools for a deliberate access policy. These features require correct configuration; they do not make an unmanaged installation automatically secure. Build a Resilient Access Layer Spanning Tree, Ethernet Ring Protection Switching and link aggregation offer different ways to plan resilient topologies. Copper ports have specified 6kV surge protection, while an optional compatible redundant supply can support power continuity. Topology, cables and power equipment must be planned together; surge protection is not a substitute for proper earthing and site protection. Manage and Maintain the Installation A Web GUI, CLI, RJ-45 console, SNMP, LLDP, sFlow and diagnostic tools support commissioning and ongoing operations. The fanless design avoids a fan in quiet work areas. Desktop and 19-inch rack installation are supported, with mounting brackets included. Keep airflow and the specified operating environment clear. Summary Choose DGS-1530-20 when 16 Gigabit connections, 10GbE uplinks and consistent managed-network controls fit the installation. Plan optics, stacking, power resilience and rack ventilation around the actual site, while keeping PoE equipment on a separately powered connection. Frequently Asked Questions Does this switch supply PoE power?ExpandCollapse No. Its Gigabit copper ports carry data only. Use a suitable PoE switch or injector for access points, cameras and other devices that require network power. How many devices can connect and what are the uplinks?ExpandCollapse The switch has 16 Gigabit copper access ports and four 10GbE SFP+ uplink ports. SFP+ optics and direct-attach cables are selected separately for the cable type, link distance and compatible equipment. Can several switches operate as one stack?ExpandCollapse Yes. Up to nine compatible units can form a physical stack using supported 10GbE links in a ring or chain. The same SFP+ ports used for stacking are then unavailable as ordinary independent uplinks. Is this a full Layer 3 router?ExpandCollapse It provides Lite Layer 3 functions including IPv4/IPv6 static routing alongside managed Layer 2 switching. Use an appropriate router or firewall when the design needs dynamic routing, WAN security or services outside this switch’s supported feature set. Is it suitable for a quiet office?ExpandCollapse The switch is fanless. Allow ventilation and keep its operating environment within −5 to 50°C. Are mounting brackets and redundant power included?ExpandCollapse Desktop and 19-inch rack installation are supported, with mounting brackets included. Redundant power is optional: DPS-200A or DPS-500A with the correct connection cable. Select the exact supply and cable for the planned installation; optics and stacking cables are also separate. 더 보기
