Before You Begin

Initial Checks

CAUTION

UNINTENTIONAL OPERATION

If you do not enter the correct address pairs into the BOOTP server, you could communicate to the wrong device.

Confirm that the MAC address matches the intended IP address in your BOOTP server.

Having two or more devices with the same IP address may cause unpredictable operation of your network.

Confirm that your Ethernet module receives a unique IP address.

Failure to follow these instructions can result in injury or equipment damage.

Complete the following checks before installing the module.

Determine how the module is assigned its Ethernet address parameters. The default method is BOOTP.
Verify that your Ethernet network is properly constructed.
Verify that you are using the proper cabling scheme for your application.

Determine the Appropriate Ethernet Address Parameters

The module obtains Ethernet address parameters in one of the following ways. Consult your system administrator to determine which method is suitable.

Configure new IP, gateway, and subnet mask addresses.

— or —
The module obtains its Ethernet address parameters from a BOOTP server.

If the administrator assigns new address parameters, configure the module through the Control Expert interface module configuration screen.

Verify the Network Topology

Schneider Electric recommends that you connect an NOE module to another NOE module or other device through a hub or a switch (as shown in the following correct network topology graphic).

The following figure shows two incorrect network topologies.
