D Link xStack Gigabit SFP Layer 234 Managed Gigabit Switch

Several DGS 3627 switches may be physically stacked, using low cost CX4 10 Gigabit copper modules. In this configuration, one or two 10 Gigabit uplinks may be created, depending on whether the linear or fault tolerant ring stacking1 is implemented. Up to 12 switches can be stacked in this way. Using the low cost coaxial cable as the medium to stack switches together provides not only high bandwidth stacking but also the flexibility to add 10 Gigabit uplinks strictly as needed. The three open slots can also be used for optional 10 Gigabit XFP fiber uplinks to servers or a backbone connection. With D Link Single IP Management SIM support, you can easily add up to 32 switch units regardless of the model in a virtual stack in addition to your physical stack. Multiple switches can be configured, monitored and maintained from any workstation running a Web browser via one single IP address. The stack is managed as a single object, as all stacked units are identified by a single IP address. A simple yet powerful web based interface allows you to perform most management and configuration tasks. A complete set of security features is provided, which includes L2L3L4 multi layer Access Control Lists ACLs and 802.1X user authentication via TACACS and RADIUS servers. The switch also offers suppression capabilities and Layer3 IPv4v6 static routing to increase network performance and security. In addition, when implemented in conjunction with a D Link NetDefend firewall, this switch as a stand alone or in a stack, is able to automatically quarantine any host displaying abnormal behaviour. Finally, D Link's ZoneDefense, provides proactive network security by preventing viruses from spreading through the network and thwarting harmful network attacks. The DGS 3627 switch provides VLAN support including GARPGVRP and 802.1Q to enhance network security and performance. The switch implements a robust set of multi layer L2, L3, L4 QoSCoS features to ensure that cr
