Chapter 3: Basic configuration

address x.x.x.254 ( “x” stands for the first three blocks in the IP address of the configuration PC).

Network with DHCP server

If a DHCP server is active in the LAN to assign IP addresses, an unconfigured LANCOM device will turn off its own DHCP server. It will change into DHCP client mode and will obtain an IP address from the DHCP server of the LAN. This IP address is not known at first. The accessibility of the device depends on the name resolution:

If there is a DNS server for name resolution in the LAN, which inter- changes the assignment of IP addresses to names with the DHCP server, then the device can be accessed by the name “LANCOM <MAC address>” (e.g. “LANCOM-00a057xxxxxx”).

The MAC address can be found on a label at the bottom of the device.

If there is no DNS server in the LAN, or it is not linked to the DHCP server, then the device can not be reached by the name. The following options remain in this case:

Figure out the DHCP-assigned IP address of the LANCOM by suitable tools and contact the device directly with this IP address.

Use LANconfig.

Connect a PC with a terminal program via the serial configuration interface to the device.

Starting the wizards in WEBconfig

Start your web browser (e.g. Internet Explorer, Netscape Navigator, Opera) and call the LANCOM there:

http://<IP address of the LANCOM>
