Overview; Factory Default Ip Settings; Using Arp To Assign An Ip Address - Moxa Technologies NPort W2250A-T-EU User Manual

NPort W2150A/W2250A Series

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 5 and 6 for
details on using the web console for configuration.
ATTENTION
The LAN and WLAN interfaces cannot be used at the same time if you don't enable the Ethernet Bridge
mode (please refer to Chapter 7 for more details). If the Ethernet link is active, then WLAN connections will
be disabled. If the WLAN connection is active, then the Ethernet link will be disabled.
ATTENTION
Make sure that the Ethernet cable is connected before powering up the NPort.

Factory Default IP Settings

If your NPort is configured to obtain its IP settings from a DHCP or BOOTP server but is unable to get a
response, 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 Device Search Utility (DSU) has found all NPorts on the network, each unit will be listed with its IP
address. Please refer to Chapter 11 for additional information on using the Device Search Utility (DSU).

Using ARP to Assign an 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.
