Assigning Ethernet Address Parameters
Overview
The following information describes how to assign IP address parameters.
As shipped from the factory, the 140 NOE 771 xx module does not contain an IP
address. If you have not programmed the unit with an Ethernet configuration
extension, the module does not contain an IP address. When the module starts up
without an IP address, the module will attempt to obtain an IP address from the
network’s BOOTP server.
You can assign IP address parameters using the BOOTP Lite software utility.
Using a BOOTP
Server
A BOOTP server is a program that manages the IP addresses assigned to devices
on the network. Your system administrator can confirm whether a BOOTP server
exists on your network and can help you use the server to maintain the adapter’s IP
address.
See Using BOOTP Lite to Assign Address Parameters, p. 74.
UNINTENTIONAL OPERATION
If you do not enter the correct address pairs into the BOOTP server, you could
communicate to the wrong device.
z Ensure that the MAC address matches the intended IP address in your BOOTP
server.
Having two or more devices with the same IP address can cause unpredictable
operation of your network.
z Ensure that your Ethernet module receives a unique IP address.
Failure to follow these instructions can result in injury or equipment damage.
Note: You can configure the IP address using Web pages on the modules
140 NOE 771 01, -11, and NWM 100 00.
