NPort 5200A Series
Initializing the NPort 5200A's IP Address
Determine whether your NPort 5200A needs to use a Static IP or Dynamic IP (either DHCP or BOOTP
application).
If the NPort 5200A is used in a Static IP environment, you can use NPort Administration Suite, ARP, Web
Console, Telnet Console, or Serial Console to configure the new IP address.
If the NPort 5200A is used in a Dynamic IP environment, you can use NPort Administration Suite, the
Web Console, the Telnet Console, or the Serial Console to configure the NPort 5200A 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 5200A 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 5200A.
Factory Default IP Address
NPort 5200A products are configured with the following default private IP address:
Default IP address:
(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 5200A 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 Administration Suite
NPort Administration Suite consists of useful utility programs that are used to configure and manage your NPort
5200A units.
See Chapter 6 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 5200A serial device servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort
5200A. The ARP command tells your computer to associate the NPort 5200A's MAC address with the intended
IP address. You must then use Telnet to access the NPort 5200A, at which point the device server's IP address
will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and the NPort 5200A must be connected to the same
LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5200A directly to your computer's
Ethernet card. Your NPort 5200A 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 5200A from your network administrator.
2. Obtain the NPort 5200A's MAC address from the label on its bottom panel.
192.168.127.254
