dows or with command ifconfig in the console under Linux). In this case, the
LANCOM can be accessed with address x.x.x.254 (the "x"s stand for the first
three blocks in the IP address of the configuration computer).
Network with DHCP server
If a DHCP server for the assignment of IP addresses is active in the LAN, an
unconfigured LANCOM device disables its own DHCP server, switches to DHCP
client mode and retrieves an IP address from the DHCP server in the LAN.
However, this IP address is initially unknown and accessing the device
depends on the name resolution:
If the LAN also has a DNS server for name resolution and this communi-
cates the IP address/name assignment to the DHCP server, the device can
be reached under name "LANCOM-<MAC address>", e.g. "LANCOM-
00a057xxxxxx".

The MAC address on a sticker on the base of the device.

If there is no DNS server in the LAN, or if it is not coupled to the DHCP
server, the device cannot be reached via the name. In this case the follow-
ing options remain:
Under LANconfig use the function "Find devices", or under WEBconfig
use the "search for other devices" option from any other networked
LANCOM.
Use suitable tools to find out the IP address assigned to the LANCOM
by DHCP and access the device directly using this IP address.
Login
When prompted for user name and password when accessing the device,
enter your personal data in the appropriate fields. Observe the use of upper
and lower case.
If you used the general configuration access, only enter the corresponding
password. The user name field remains blank in this case.
