LAN Interface Card Configuration
Since the default IP address is a so- called local address, it will not be
routed by any network device. Thus, the PC and the card must reside in
the same subnet.
The user may open a Telnet session using the default IP address and
change the parameters stored in the non- volatile memory of the card. He
may then close the session, select the initialization mode “Using Stored”,
power- on again and establish the TCP/IP connection using the new
parameters.
When the card is wired to the PC directly (e.g. using a cross- over cable or
a local hub), separated from the local area network, the user may simply
keep the default parameters to establish the TCP/IP connection.
DHCP
When the initialization mode “DHCP” is selected, the card tries to
download the parameters from a DHCP Server. The parameters obtained
become the active parameters immediately. They are not stored to the
non- volatile memory of the card.
Beside requesting the network parameters, the card also submits its
hostname to the DHCP Server. The hostname equals the MAC address of
the card, e.g. "0030d3177321". It is the DHCP server's responsibility to
forward the hostname/address information to the Domain Name Server.
The card does not offer any services for hostname resolution (e.g.
NetBIOS).

In the “Using Default” mode, the parameters stored in the memory of the card are not
cleared automatically. If not changed by the user, they are still available, when switching
back to the mode “Using Stored”.
