Data Rate: 1000Mbps/1Gbps Model: DGS-3420-52T Ethernet Technology: Gigabit Ethernet (1000-Mbit/s) MPN: DGS-3420-52T Type: Ethernet Switch Layer: 3 Dlink xStack 48-port Layer 2+ Stackable Managed PoE Gigabit Switch +4 10GE SFP+ In Good Condition, Full Working OrderIncludes Rack Mount Ears Included:1 x D-Link DGS-3420-52T xStack 48-Port 4x 10GbE SFP+ Ports Stackable Gigabit SwitchDescription:The D-Link DGS-3420-52T 48-Port xStack Layer 2+ Stackable Gigabit Switch delivers performance, flexibility, security, multi-layer QoS and access control, along with redundant power solutions for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP and 10-Gigabit SF + support, and advanced software solutions, the D-Link DGS-3420-52T can act as either a departmental access layer device or as an aggregation switch to form a multilevel network structured with backbone and centralised high-speed servers. Service providers can take advantage of this high SFP density switch to structure the aggregation of Fibre to the Building (FTTB) networks that they extend to the subscriber's sites.Key FeaturesForty-Eight (48) 10/100 fast Ethernet RJ45 Network ports with auto-MDIX sensing.Four (4) dedicated Gigabit ports support high-speed SFP uplinks or fiber connectivity.Multiple functions such as switching and routing to eliminating the need of multiple routers and switches.Physical stacking architecture: up to 576 Gigabit ports on a single stack.Web-based GUI for easy management.Comprehensive security features, including Microsoft NAP.Comprehensive IPv6 support.SD card slot to store and restore configuration files.Green technology - Power-saving mode, Smart Fans.Unparalleled FlexibilityEasily deployed and simple to manage, the D-Link DGS-3420-52T can be virtually stacked with any switch that supports D-Link's Single IP Management (SIM) to form a multi-level network structured with backbone and centralised high-speed servers. The virtual stack can include units located anywhere on the same network domain, eliminating cable distance barriers, limitations of physical stacking, and the need for stack cabling.Redundant Ring StackingAlternatively, depending on whether linear or fault-tolerant ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack1. Switches in the stack are hot-swappable to minimise network downtime in case a replacement is required, eliminating single points of failure. Up to 12 units or 576 Gigabit ports can be configured for a stack using direct attached cables1 allowing high bandwidth and high port densities on the already cost efficient D-Link DGS-3420-52T switch.Security, Performance and AvailabilityThe D-Link DGS-3420-52T provides a complete set of security features including L2/L3/L4 multi-layer Access Control Lists and 802.1x user authentication via TACACS+ and RADIUS servers. This D-Link DGS-3420-52T offers extensive VLAN support including GVRP and 802.1Q VLAN to enhance security and performance. A robust set of L2/L3/L4 QoS/CoS solutions help ensure that critical network services such as VoIP, ERP, Intranet, and video conferencing are served with proper priority. The D-Link DGS-3420-52T provides D-Link's Safeguard Engine to increase the switch's reliability, serviceability, and availability to prevent malicious flooding traffic caused by worms or virus infections. Bandwidth Control can be flexibly set for each port using pre defined thresholds to assure a committed level of service for end users. For advanced applications, flow-based bandwidth control allows easy fine tuning of service types based on specific IP addresses or protocols.IPv6 TechnologyThe D-Link DGS-3420-52T also features comprehensive IPv6 support, including IPv6 Tunneling, ICMPv6, DHCPv6, RIPng, etc. With 10-Gigabit connectivity and IPv6 support, the DGS-3420 Series enables you to future-proof your network for cost efficiency and longevity while meeting the requirements for IPv6 capable network devices in the coming years.D-Link Green TechnologyD-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The D-Link DGS-3420-52T implements the D-Link Green Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and cable length detection. The power saving feature automatically powers down ports that have no active link. The Smart Fan feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.Specification:StackabilityVirtual Stacking SupportD-Link Single IP ManagementUp to 32 devices per virtual stackUp to 20G stacking bandwidthPhysical StackingSupports Duplex Chain/Ring topologyUp
