Chapter 1 Install a 1756 EtherNet/IP Communication Module
Set the Network IP Address with the BOOTP/DHCP Server
The BOOTP/DHCP server is a standalone server you can use to set an IP
address. When used, the BOOTP/DHCP server sets an IP address and other
Transport Control Protocol (TCP) parameters.
You can use the BOOTP/DHCP server to set the module’s IP address if one of
these conditions exists at powerup:
• The module’s rotary switches are not set to a valid number and the module
is BOOTP/DHCP enabled.
• The module does not have rotary switches and the module is
BOOTP/DHCP enabled.
Access the BOOTP/DHCP server from one of these locations:
• Programs > Rockwell Software > BOOTP-DHCP Server
If you have not installed the server, you can download and install it from
• Tools directory on the Studio 5000 environment installation CD
Follow these steps to set the module’s IP address with a BOOTP/DHCP server.
1. Start the BOOTP/DHCP software.
2. From the Tools menu, choose Network Settings.
IMPORTANT
Before you start the BOOTP/DHCP server, make sure you have the
module’s hardware (MAC) address. The hardware address is on a sticker
on the side of the communication module and uses an address in a
format similar to the following:
00-00-BC-14-55-35
