VOLKTEK’s NSH-2926 is a gigabit web smart switch. Easily boosting networking throughput, NSH-2926 provides sixteen 10/100/1000Mbps Gigabit Ethernet ports that offer a true Gigabit connection. Users are now able to transfer large files faster and achieve real efficiency improvements with the user-friendly Web-based management interface. The NSH-2926 also includes two mini-GBIC combo slots for flexibility in fiber connection options.

The management functions provide efficient network usage. VLAN reduces the collisions from wide broadcasting, while Port Aggregation enlarges the bandwidth of the backbone connection. QoS is supported to secure the bandwidth for high bandwidth applications including VoIP and video conferencing, and 802.3x and backpressure flow control mechanisms are also supported to ensure faithful data transmission.
