NPort 5200 Series Initial IP Address Configuration
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort 5200 from your network administrator.
2. Obtain the NPort 5200’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
5200. (Be sure to use the actual IP address and MAC address for your NPort 5200.)
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 5200
reboots, its IP address will be updated to the new address, and you can reconnect using either Telnet, Web,
or Administrator to check that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use network
access to set up your NPort 5200’s IP address. This can be done using the Telnet.
1. From the Windows desktop, click on Start and then select Run.
2. Type telnet 192.168.127.254 (use the correct IP address if different from the default) in the Open text
input box, and then click on OK.
3. When the Telnet window opens, if you are prompted to input the Console password, input the password
and then press Enter.
Note that this page will only appear if the NPort 5200 is password protected.
