Assigning Ethernet Address Parameters
Overview As shipped from the factory, the M1 Ethernet Processor does not contain an IP
address. This is also true if you have not programmed the unit with an Ethernet
configuration extension. In this condition, when the module starts up, it will attempt
to obtain an IP address from the network’s BOOTP server.
You can use Concept to assign an IP address, default gateway and sub network
mask. See

Setting Ethernet Address Parameters

on page 348.
You can also assign IP address parameters using the BOOTP Lite software utility.
See

Using BOOTP Lite to Assign Address Parameters

on page 152.
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 ad apter’s IP
address.
How an
unconfigured
(“as shipped”)
module obtains
an IP address
On startup, an unconfigured processor will attempt to obtain an IP address by
issuing BOOTP requests. When a response from a BOOTP server is obtained, t hat
IP address will be used. If a response is not heard, then the Bootp requests will
continue for as long as the unit remains powered or until a response is heard.
Specifying
Address
Parameters
Consult your system administrator to obtain a valid IP address and appropriate
gateway and subnet mask, if required. Then follow the instructions in

Setting

Ethernet Address Parameters

on page 348.

CAUTION
DUPLICATE ADDRESS HAZARD
Be sure that your Processor Adapter will receive a unique IP address. Having two or more
devices with the same IP address can cause unpredictable operation of your network.
Failure to observe this precaution can result in injury or equipment damage.
