NPort IA and IAW5000A-I/O

Overview

This chapter presents several ways to assign the NPort's IP address for the first time. Please refer to
Chapter 2 for instructions on connecting to the network.
The web console is the recommended method for configuring the NPort. Please refer to Chapter 6 to 12 for
details on using the web console for configuration. With the NPort's default setting (Ethernet Bridge function
disabled), please ensure the Ethernet cable is connected before powering up the NPort. Then, proceed to
following IP configuration options.

If your NPort is configured to obtain its IP settings from a DHCP or BOOTP server, but it is unable to get a
response, then it will use the factory default IP address and netmask.
ATTENTION
If you forget the IP address of your NPort, you can look it up using the Device Search Utility (DSU). After
the DSU has found all NPorts on the network, each unit will be listed with its IP address. Please refer to
Chapter 5 for additional information on using the DSU.

Using ARP to Assign IP Address

The ARP (Address Resolution Protocol) command can be used to assign an IP address to the NPort. The ARP
command tells your computer to associate the NPort's MAC address with the specified IP address. You must
then use Telnet to access the NPort, at which point the device server's IP address will be reconfigured. This
method only works when the NPort is configured with default IP settings.
1. Select a valid IP address for your NPort. Consult with your network administrator if necessary.
2. Obtain the NPort's MAC address from the label on its bottom panel.
3. From the DOS prompt, execute the arp -s command with the desired IP address and the NPort's MAC
address, as in the following example:
arp -s 192.168.200.100 00-90-E8-xx-xx-xx
In this example 192.168.200.100 is the new IP address that will be assigned to the NPort, and 00-90-
E8-xx-xx-xx is the NPort's MAC address.
4. From the DOS prompt, execute a special Telnet command using port 6000, as in the following example:
telnet 192.168.200.100 6000
In this example, 192.168.200.100 is the new IP address that will be assigned to the NPort.
