LANCOM 821 ADSL/ISDN – LANCOM 1621 ADSL/ISDN – LANCOM 1711 VPN

Chapter 2: Installation

The LAN connector identifies automatically the transfer rate (10/100 Mbps) of the connected network device (autosensing). A parallel connec- tion of devices with different speeds and types is possible.

You should never have more than one unconfigured LANCOM in a network segment at any given time. All unconfigured LANCOM devices use the same IP address (with the final digits '254'), which would result in an address conflict. To avoid problems, always config- ure multiple LANCOM devices one at a time, immediately assigning each device a unique IP address (one that does not end with '254').821/1621 only
