Initializing NPort 5200’s IP Address
1.
Determine whether your NPort 5200 needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2.
If NPort 5200 is used in a Static IP environment,
you can use NPort 5200 Administration
Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.
3.
If NPort 5200 is used in a Dynamic IP environment,
you can use NPort 5200 Administration
Suite, Web Console, Telnet Console, or Serial Console to configure NPort 5200 to get an IP
address dynamically with DHCP, DHCP/BOOTP, or BOOTP.
ATTENTION
Consult your network administrator to learn how to reserve a fixed IP address for your NPort
5200 in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. For most
applications, you should assign a fixed IP address to your NPort 5200.
Factory Default IP Address
NPort 5200 device servers 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 access a device configured with a private IP address directly from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort 5200 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.)
NPort 5200 Administration Suite
NPort 5200 Administration Suite consists of useful utility programs that are used to configure and
manage your NPort 5200 device server.
See Chapter 5 for details on how to install NPort 5200 Administration Suite, and how to use
this suite of useful utilities to set up IP addresses and configure your NPort 5200 Series serial
device servers.
ARP
You can use the ARP (Address Resolution Protocol) command to set up an IP address for your
NPort 5200. The ARP command tells your computer to associate the NPort 5200’s MAC address
with the intended IP address. You must then use Telnet to access the NPort 5200, 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 5200 must be connected to the
same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5200 directly to
your computer’s Ethernet card. Your NPort 5200 must be configured with the factory default IP
address

before executing the ARP command, as described below.
