S3928 is a standard L3 congestion-less switch series, which are capable of multi-layer
switching and wire-speed route forwarding. Its high-performance ASIC and modular design
enable users to employ a suitable number of interfaces and to configure scales of their
networks with great flexibility, all based on their individual requirements. It supports
plenty of access authentication models that can be flexibly configured, making it especially
ideal for community access networks. Due to its high performance and low cost, TECHROUTES S3928
is considered a very competitive Ethernet switching solution for community networking and
workgroup networking in enterprise networks.

Application

Aggregation level of large enterprise networks
Giga core of small- to Medium-sized business networks
Connection server cluster of data centers
High performance-price ratio multi-layer switching solution in other situations where multiple Giga ports are needed.
