Initializing NPort IA5150/5250’s IP Address
1. Determine whether your NPort IA5150/5250 needs to use a Static IP or Dynamic IP (either
DHCP or BOOTP application).
2. If NPort IA5150/5250 is used in a Static IP environment, you can use NPort IA5150/5250
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the
new IP address.
new IP address.
3. If NPort IA5150/5250 is used in a Dynamic IP environment, you can use NPort
IA5150/5250 Administration Suite, Web Console, Telnet Console, or Serial Console to
configure NPort IA5150/5250 to get an IP address dynamically with DHCP, DHCP/BOOTP,
or BOOTP.

ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your NPort
IA5150/5250 in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In
most applications, you should assign a fixed IP address to your NPort IA5150/5250.

Factory Default IP Address
NPort IA5150/5250 products are configured with the following default private IP address:
Default IP address:
192.168.127.254
(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not
possible to directly access a device configured with a private IP address from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort IA5150/5250 applications that require sending data over a public network, such as the
Internet, require setting up the server with a valid public IP address, which can be leased from a
local ISP.)

ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort IA5150/5250. The ARP command tells your computer to associate the NPort
IA5150/5250’s MAC address with the intended IP address. You must then use Telnet to access the
NPort IA5150/5250, at which point the device server’s IP address will be reconfigured.

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.
