Description

A new generation of switches series xStack DGS-3420 provides networks of large enterprises and small and medium-sized business (SMB) high performance, flexibility, security, and multi-level quality of service (QoS). Switches provide high-density Gigabit Ethernet ports for connecting workplaces equipped with SFP ports and 10 Gigabit SFP + support and advanced features of the software. The switches can be used as a device-level access or aggregation in order to create a multi-level network structure with high-speed backbone and centralized servers connection. Service providers can also take advantage of switches with high port density SFP (eg, DGS-3420-28SC / 26SC) to form aggregation layer optical network (FTTB).

All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable.
