NPort 5110 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 5110 from your network administrator.
2. Obtain NPort 5110’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 5110. You will need to change both numbers, as described above in
items 1 and 2.
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 5110 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 5110’s IP address. This can be done using 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 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 5110 is
password protected.
