NPort W2150/2250 Plus Series User’s Manual Initial IP Configuration
3-2
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 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
Network Interface IP Configuration IP Address Netmask
LAN Static 192.168.126.254 255.255.255.0
WLAN Static 192.168.127.254 255.255.255.0
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 NPort Search Utility. After
NPort Search Utility 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 NPort Search Utility.
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.
