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
