Status : mới
26-port Gigabit L2 Stack-Managed D-Link DGS-3420-26SC / E
-20 SFP ports + 4 Combo 10/100/1000 Base-T / SFP ports + 2 ports 10 Gigabit SFP + Slots.
- / E: EU 2 round pin power cord.
-Physical stack up to 12 units, 576 Gigabit ports, up to 40G Full-duplax Stacking bandwidth.
ITU-T Support G.8032 Ethernet Ring Protection Switching (ERPS)
-Provides a complete set of security features L2 / L3 / L4 multi-layer Access Control Lists
-Supports 802.1X user authentication via TACACS + and RADIUS servers
-Offers extensive VLAN support including GVRP, 802.1Q VLAN to enhance security and performance.
-Robust set of QoS / CoS solutions for critical network services (VoIP, ERP, Intranet, conferencing).
-Support 802.1 ag Connectivity Fault Management (CFM) and 802.3 ah Ethernet OAM

-Green Technology- Power saving mode, time-based PoE and Smart Fan.
The DGS-3420 Series xStack L2 Managed Stackable Gigabit Switches are next generation switches that deliver, flexibility, security, multi-layer QoS, and accessibility, along with redundant power solutions for SMBs and enterprises.
-With high-speed Gigabit port, Gigabit SFP, 10-Gigabit SFP + support, and advanced software solutions, these switches can be as if departmental access layers or aggregation switches to form a network multilevel structured with backbone and centralized high-speed servers.
-Service providers can take advantage of the high density SFP switches (such as DGS-3420-26SC / E) to structure the aggregation of Fiber to the Building (FTTB) networks that extend to subscribers' sites.
Unparalleled Flexibility
-Easily deployed and simple to manage, the DGS-3420 Series switches can be stacked with any switch that supports D-Link's Single IP Management to form a multi-level network structured with backbone and centralized high-speed servers.
-The virtual stack can include units located anywhere on the same network domain, and uses optional 10-Gigabit uplinks to move intrastack traffic at 20 Gbps full duplex speeds.
D-Link Green Technology
-D-Link is striving to take the lead in developing creative and power-saving technology không phải thực hiện việc thực hiện hoặc thiết kế.
-The DGS-3420 implements Series Green technology D-Link, which includes power saving through status link, smart fan design, increased heat dissipation, and cable length detection. Tập tin power-cấu hình tự động tự động tự động đến các cổng, không có kết nối hoặc liên kết thành viên.
-The Smart Fan design allows the built-in fans to automatically turn on only at a certain temperature, providing continuous, reliable, and eco-friendly operation.
Redundant Ring Stacking
-Alternatively, 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 stack.3 12 units or 576 Gigabit ports can be configured for a stack using directly attached cables để cung cấp cao bandwidth trên DGS-3420 Series with cost efficiency.
-Support for virtual stacking provides further convenience by allowing centralized management of ports across different locations for simplifying large-scale deployments.
IPv6 Technology
-The DGS-3420 Series also features comprehensive IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6, RIPng, IPv4 / IPv6 dual stack, and more. With 10-Gigabit connectivity and IPv6 support, the series can help you futureproof network for cost efficiency and while meeting the requirements of IPv6-capable network devices.
Security, Performance & Availability
-The DGS-3420 Series provides a complete set of security features including L2 / L3 / L4 multi-layer Access Control Lists and 802.1X authentication users via TACACS + and RADIUS servers. The DGS-3420 Series 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 series also provides D-Link's Safeguard Engine to increase reliability, serviceability, and availability by preventing malicious flooding of traffic caused by worms or virus infections.
-Bandwidth Control may be flexibly set for each port using pre-defined thresholds to assurance a commit 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.
Comprehensive Management
-The DGS-3420 Series provides a breadth of features to manage manage network administrators and troubleshoot the network with ease. Provision for a centralized web-based GUI, Command Line Interface (CLI), Telnet, Flash File System, multiple images / configurations, and CPU monitoring reduce the time spent on network configuration.
-Support for device-based and flow-based monitoring such as SNMP, Syslog, RMON, and sFlow ensure smooth performance throughout the network. Lastly, features such as Cable Diagnostics and Connectivity Management (CFM) round out the OAM switch capabilities to help administrators save time during troubleshooting scenarios.
