hi, we replaced a 1900 series switch with a 2960 switch but now we have a michine that cannot connect to the LAN. when u plug in the cable its connecting to a 1gbps network yet we oprate on a 100mbps network. ip assigining is done by the DHCP. Tried connecting a different machine to the point its said limited connectivity. tried pinging the switch from the different machine its saying destination host unreachable.
