Initializing WE-2100T’s IP Address
1. Determine whether your WE-2100T will use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2. If WE-2100T is used in a Static IP environment, you can use Network Enabler
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the
new IP address.
3. If WE-2100T is used in a Dynamic IP environment, you can use Network Enabler
Administration suite, Web Console, Telnet Console, or Serial Console to configure
WE-2100T to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.
Consult your network administrator on how to reserve a fixed IP address (for your WE-2100T) 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 WE-2100T module.
Factory Default IP Address
WE-2100T is configured with the following default private IP address:
Ethernet default IP address: 192.168.126.254
WLAN 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.
WE-2100T 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.)
Network Enabler Administration Suite
Network Enabler Administration Suite consists of some useful utilities that are used to configure
and manage your WE-2100T embedded module.
See Chapter 7 for details on how to install Network Enabler Administration Suite, and how
to use this suite of useful utilities to set up IP addresses and configure your WE-2100T
embedded module.
ARP
You can use the ARP (Address Resolution Protocol) command to set up an IP address for your
WE-2100T. The ARP command tells your computer to associate the WE-2100T’s MAC address
with the intended IP address. You must then use Telnet to access the WE-2100T, at which point
the WE-2100T’s IP address will be reconfigured.
In order to use this setup method, both your computer and WE-2100T must be connected to the same
LAN.
You may also use a cross-over Ethernet cable to connect the WE-2100T directly to your computer’s
Ethernet card.
Your WE-2100T 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 WE-2100T from your network administrator.
2. Obtain the WE-2100T’s MAC address from the label on the module.
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:
