Chapter 3 Installing the Module
Assigning Ethernet Address Parameters
Overview
As shipped from the factory, the NOE 771 x0 module 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 Configuring the Ethernet Address Parameters in Chapter 4.
You can also assign IP address parameters using the BOOTP Lite software utility.
See Using BOOTP Lite to Assign Address Parameters in this chapter.
CAUTION
DUPLICATE ADDRESS HAZARD
Be sure that your NOE 771 x0 module 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.
Using a BOOTP
Server
A BOOTP server is a program which 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.
How an
unconfigured
(“as shipped”)
module obtains
an IP address
On startup, an unconfigured NOE 771 x0 module will attempt to obtain an IP
address by issuing BOOTP requests. When a response from a BOOTP server is
obtained, that IP address will be used. If there is no BOOTP response received in
two minutes, the module will use the default IP Address.
