The H3C S7600 series carrier-grade high-end routing switches are a new generation of metropolitan area network (MAN) equipment launched by H3C Technologies Co., Ltd. (hereinafter referred to as H3C) for the metropolitan area Ethernet market. Compared with traditional enterprise-grade Ethernet switches, the S7600 series routing switches have made a qualitative leap in terms of table capacity, QoS, reliability, manageability, multi-service support capabilities, and network security. They are truly carrier-grade IP switching products, capable of providing high-capacity, high-reliability, and stringent QoS service carrying guarantees for carrier MANs, data centers, and other applications.

The H3C S7600 series of routing switches includes seven main models: S7602-S, S7603, S7603-S, S7606, S7606-S, S7606-V, and S7610. These models can adapt to port densities and performance requirements of different network sizes, providing strong equipment support for operators building multi-service integrated metropolitan area networks. The S7600 series routing switches, together with H3C's series of routers, Ethernet switches, and iMC network management system, provide operators with a complete range of solutions for metropolitan area Ethernet networking.
