MiiNePort E2/E3
Static vs. Dynamic IP Address
You should first determine whether the module will be assigned a Static IP or Dynamic IP (either DHCP or
BOOTP application).
•
If the module is used in a Static IP environment, you need to configure the IP address directly.
•
If the module is used in a Dynamic IP environment, you need to configure the module to obtain an IP
address dynamically with DHCP, DHCP/BOOTP, BOOTP, or AUTOIP.
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 MiiNePort module is configured with the following default private 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. 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 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 crossover 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.
To configure the IP address using ARP, follow these instructions:
1. Obtain a valid IP address for the module from your network administrator.
2. Obtain the module's MAC address from the label on the module.
3. Execute the arp -s command from your computer's MS-DOS prompt by typing:
arp –s <new IP address> 00-90-E8-tt-tt-tt
For example,
arp –s 192.168.200.100 00-90-E8-00-00-00
In this example, 192.168.200.100 is the new IP address and 00-90-E8-00-00-00 is the module's MAC
address, as obtained in steps 1 and 2.
4. Execute a special Telnet command by typing:
telnet <new IP address> 6000
For example,
telnet 192.168.200.100 6000
