NPort IA5150/5250 Series User’s Manual 
Initial IP Address Configuration 
 
3-3
Take the following steps to use ARP to configure the IP address: 
1.  Obtain a valid IP address for your NPort IA5150/5250 from your network administrator. 
2.  Obtain NPort IA5150/5250’s MAC address from the label on its bottom panel. 
3.  Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing: 
arp -s 192.168.200.100 00-90-E8-xx-xx-xx 
This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC 
address for your NPort IA5150/5250. (Be sure to use the actual IP address and MAC address 
for your NPort IA5150/5250.) 
4.  Next, execute a special Telnet command by typing: 
 
telnet 192.168.200.100 6000 
After issuing this command, a Connect failed message will appear, as shown here. After the 
NPort IA5150/5250 reboots, its IP address should be updated to the new address, and you can 
reconnect using either Telnet, Web, or Administrator to check that the update was successful.

Depending on how your computer and network are configured, you may find it convenient to use 
network access to set up your NPort IA5150/5250’s IP address. This can be done using Telnet.
