To double the available bandwidth, each port supports an Auto-Negotiation function that automatically places the network speed at its maximum level. When linked to other 100Mbps devices, each port can be set to forced 100Mbps Full Duplex mode via its DIP switch. Setting a port to forced 100Mbps Full-Duplex mode creates an independent segment that transmit data at collision-free 200Mbps! The CNSH-500 divides each port's traffic onto its own individual segment. This cuts a network's traffic load and reduces collisions on each segment. Network traffic can be further reduced by placing users (ex. Departments) and devices that normally talk to each other onto the same segment. The CNSH-500 also provides a Crossover function for Uplinking to a standard port on another Hub. Every port is capable of operating in an Auto-Negotiation mode, or can be set to a froced 100Mbps Full-Duplex mode by flipping the port's DIP switch. In every mode, this model provides capable of wire-speed "Forwarding and Filtering" rates that eliminate bad packets with minimal delay. This is a Plug and Play device. No software configuration is required. Users simply attach the proper cables, then turn the Hub "On". Each port automatically creates a separate collision domain that delivers data transmissions to connected devices at speeds ranging from 10Mbps to 200Mbps.
