D-Link DGS-3420-28TC Managed network switch L2+ Power over Ethernet (PoE) network switch

xStack L2+ Managed Stackable Gigabit SwitchesThe xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers performance,flexibility, security, multi-layer QoS, and accessibility, along with redundant power solutions for SMBsand enterprises. With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advancedsoftware solutions, these switches can act as either departmental access layer devices or aggregationswitches to form a multilevel network structured with backbone and centralized high-speed servers.Service providers can take advantage of the high SFP density switches (such as DGS-3420-28SC/26SC) to structure the aggregation of Fiber to the Building (FTTB)networks that are extended to the subscribers’ sites.Unparalleled FlexibilityEasily deployed and simple to manage, the DGS-3420 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 thesame network domain, and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full duplex speeds.Redundant Ring StackingAlternatively, depending on whether linear or faulttolerant ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack. 12 units or 576 Gigabit ports can be configured for a stack using direct attach cables to provide high bandwidth on the DGS-3420
