NPort IA5150/5250 Series User’s Manual
Initial IP Address Configuration
3-3
ATTENTION
In order to use this setup method, both your computer and NPort IA5150/5250 must be
connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort
IA5150/5250 directly to your computer’s Ethernet card. Before executing the ARP command,
your NPort IA5150/5250 must be configured with the factory default IP address
(192.168.127.254), and your computer and the NPort IA must be on the same subnet.
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 the 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 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.
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 IA5150/5250’s IP address. This can be done using Telnet.
