    Auto-Negotiation feature targets the maximum capabilities that can be reached between the two devices. For example, an FE-100TX Fast Ethernet Interface Module in a 2E43-51 can adjust to 100 Mbps when the device on the other end of the connection can also adjust to 100 Mbps. If the device on the other end of the connection can only operate at 10 Mbps, then the FE-100TX simply adjusts to 10 Mbps operation.

    IP Address Discovery (RAD) checks the 2E43-51 for an IP address. If one has not yet been assigned (2E43-51 IP address set to 0.0.0.0), RAD checks to see if any of the 2E43-51 interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a BootP server on the network.
