Hospital Campus Network Clinic Ward Office building Medical network Internet Remote treatment S12700 S7700 S5700 Intranet data center Router eSight Campus CSS2 HIS/LIS/PACS/RIS Remote access AC Inside AP Wired and wireless convergence The S12700 is the first agile switch in the world. The S12700 supports native T-bit AC, enables wireless signals to cover every corner, and allows anytime and anywhere access to medical service. Integrated forwarding: The native T-bit AC can manage 4K APs and 64K users, integrating management and forwarding. The external AC or AC subcard may become a bottleneck in forwarding, but the native AC will not; therefore, the native AC meets the PACS service requirements in future. Reliable network: The industry-leading CSS2 technology is highly reliable, and does not occupy service slots. Uniform authentication: The switch supports MAC address, Portal, and 802.1x authentication methods to ensure the service experience and information security of users in different areas. Efficient management: The switch uses exclusive technology to manage access switches and APs to construct the first Zero-Touch network at the access layer. The network operation and maintenance of the hospital is simplified. 2
