The x Stack DGS-3426P next generation switch delivers performance, flexibility, security, multi-layer Quality of Service (Qo S) & redundant power option for the SMB & enterprises. With high Gigabit port densities for desktop connections, SFP fibre connectivity, 10-Gigabit uplink options & enhanced Layer 2+ functions, this switch comprises the workgroup access-layer stack for seamless integration with L3 core switches to form part of a multilevel network structured with high-speed backbone & centralized servers. The DGS-3426P can operate as a st&-alone device or part of a scalable stack. Embedded with Single IP Management capability, a st&-alone switch can form part of a virtual stack, where intra-stack traffic flows through the usual network wires, doing away with the costly stacking cables. Without stacking cables, cable distance barriers & physical stacking limitations, a virtual stack can comprise units that are located anywhere on the network that minimizes the impact of any single point of failure. Alternatively, optional 10-Gigabit modules can be installed in the open slots to create a physical stack. Up to 12 units or 288 Gigabit ports can be configured for a stack. Users can install one or two single-port modules, depending on whether the fault-tolerant Ring or Star stacking is implemented. With each of these ports providing 20 Gbps full duplex transmission on the cost-effective CX4 cable, the DGS-3426P provides not only high-bandwidth stacking but also cost control capability that allows users to add ports strictly on a per need basis. Modules with single 10-Gigabit XFP can also be installed in any of the open slots for uplink to a server or a fibre backbone. The DGS-3426P provides up to 15.4W power on all 10/100/1000 Mbps ports. It complies with the IEEE 802.3af standard, delivering power over cat 5 Ethernet cable for Po E-capable wireless APs, IP cameras & IP phones. The DGS-3426P provides a complete set of security features, which
