At default, Conettix IP products use an automatic private IP address (APIPA). The IP address range of APIPA is 169.254.0.1 to 169.254.255.255. The IP address 169.254.255.255 is the multicast address of the 169.254.0.0 network.
The following procedure will get you into a Conettix IP product that is setup for DHCP. By default, a new Conettix IP product will use the DHCP range. You must be using either a crossover cable, or you may use a switch or hub that does not block a multicast message. This procedure requires that the PC you are on must be setup for DHCP, and it must have already failed the process in obtaining a DHCP address (this normally takes about two minutes in Windows). This can be verified by running the command IPCONFIG from a command prompt, and then verifying the IP address for the Ethernet Adapter Local Area Connect is in the APIPA range (e.g. 169.254.x.x).
Open a command prompt in Windows by going to Start, All Programs, Accessories, and Command Prompt. Use the following commands.
