NPort Administration Suite
NPort Administration Suite consists of some useful utility programs that are used to configure and
manage your NPorts.
See Chapter 5 for details on how to install NPort Administration Suite, and how to use this suite
of useful utilities to set up IP addresses and configure your NPort.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort. The ARP command tells your computer to associate the NPort’s MAC address with the
intended IP address. You must then use Telnet to access the NPort, at which point the Device Server’s
IP address will be reconfigured.
In order to use this setup method, both your computer and NPort must be connected to the same LAN.
Or, you may use a cross-over Ethernet cable to connect the NPort directly to your computer’s Ethernet
card.
Your NPort must be configured with the factory default IP address—192.168.127.254—before
executing the ARP command, as described below.
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort from your network administrator.
2. Obtain the NPort’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. You will need to change both numbers, as described above in points 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 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.
