I am trying to use bootp to set an ip address in a new Compactlogix 1769-L35 processor. I have a pc running bootp and its connected thru a switch to the compactlogix. I dont see the link lights on the plc or the switch, and dont see any mac adresses in bootp. Tried other ports on the switch that I know work...nothing. Keyswitch in any special position? What am I missing here?
