NE-4100 Series User’s Manual Initial IP Address Configuration
5-2
Static vs. Dynamic IP Address
Determine whether the module will use a Static IP or Dynamic IP (either DHCP or BOOTP
application).
z If the module is used in a Static IP environment, you will configure the IP address directly.
z If the module is used in a Dynamic IP environment, you will configure the module to obtain
an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for the module 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 the module.
Factory Default IP Address
The module is configured with the following default private IP address:
192.168.127.254
Please note that 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. 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.
NE-4100 Series Administration Suite
The NE-4100 Series Administration Suite consists of some useful utilities that are used to
configure and manage the module. Please refer to
Chapter 7 for details on using the NE-4100
Series Administration Suite to set up the module’s IP addresses.
ARP
You can use the ARP (Address Resolution Protocol) command to set up the module’s IP address.
The ARP command tells your computer to associate the module’s MAC address with the intended
IP address. You must then use Telnet to access the module, at which point the module’s IP address
will be reconfigured.
ATTENTION
In order to use ARP, both your computer and the module must be connected to the same LAN.
You may also use a cross-over Ethernet cable to connect the module directly to your computer’s
Ethernet port.
Your module must be configured with the factory default IP address before executing the ARP
command.
