D-Link DGS-3627G

Switch D-LINK DGS-3627G is part of a family L3 Gigabit Switch D-Link xStack that represent a combination of performance with robust security, QoS (Quality of Service), versatile management functions, Redundant power supply options and ease of expansion.With its 24 SFP slots provides all-optical environment for large Ethernet infrastructure.It is particularly suitable for telecom service providers, which can form the basis of their optical network nodes installed in individual buildings and expand the coverage area.For greater flexibility are built four 1000Base-T copper ports that serve as ports with 4 combo SFP slots.

Several DGS-3627G switch can be connected to the physical stack using cheap 10gigabitových CX4 copper modules.In this configuration, it is possible to create one or two 10-Gigabit uplinks, depending on whether it is implemented linear or lunge tolerant ring stacking.This way you can create a stack of up to 12 switches.Using inexpensive coaxial cable for stacking switches enables not only broadband but also flexible stacking 10gigabitových adding uplinks exactly as needed.Three open slots can also be used for 10-Gigabit XFP fiber uplinks to servers or backbone connection.

With D-Link Single IP Management (SIM), you can connect up to 32 switches (regardless of model) to the virtual stack.Group of switches can be configured, monitored and managed through a single IP address from any workstation with a web browser.Stack is operated as a single object and all stacked units are identified by a single IP address.Simple but powerful web interface, allowing administrators to perform most tasks for configuration and management.

For a secure connection and access control is a complete set of security features.These include access lists (Access Control List-ACL) based on MAC address, switch port, IP address numbers, or TCP/UDP ports.The switch supports 802nd1X authentication via TACACS + and RADIUS.In addition, this switch is able to deploy a firewall in cooperation with the D-Link NetDefend automatically block each host that exhibits unusual behavior.This mechanism, called D-Link ZoneDefense ™, provides proactive network security by preventing the spread of the virus through the network and thwarting attacks on Network1.

The DGS-3627G switch supports VLAN functions using GARP/GVRP, 802nd1Q and Guest VLAN to enhance network security and performance.Guest VLAN function dynamically classifies users into "VLAN host" if a user is not logged on to the RADIUS server.Bandwidth control allows administrators to set bandwidth limits for each port to ensure the required level of service for end users.Unique features D-Link Safeguard Engine allows administrators to configure thresholds that limit the influence of extreme network load caused by the usual and virus/worm on the CPU switch.This increases reliability, serviceability and availability switch.
