These KMC/I-112 series fast internet media converters with internal power supply, can divide the network into to several conflicting territories and realize the redundant link automatic activation function. The exchanging function acts as "the bridge" in many data links. Compared with the sharing type band width, it has produced a larger network. Each port can automatically negotiate with the port speed of the linked equipments. Is it 10 Mbps or 100Mbps? Is it half-duplex or full duplex? The flow control is also carried on by the negotiation. The PAUSE policy is adopted on the full duplex webpage, and the backpressure policy is automatically used on the half-duplex webpage. The switchboard will find out the port position of the linked Ethernet equipment according to the source address after it reads a complete frame. The exchanging function produces a port address form immediately and maintains the content of the form.
This stand-alone media converter has internal power source. The module type media converter can be installed on the 19'' 2U chassis HMC-16C. With internal power supply system, it can hold 16 medium switches at most. In to the situation requesting strict reliability, the second redundant power source can be installed to provide the higher reliability.
