Hardware installation
The installation of the LANCOM Router base station takes place in the follow-
ing steps:
Antennas
– screw the antennas supplied to the back of the LANCOM
Wireless Router. Depending on how the antennas are to be used, the
'Antenna Grouping' parameter may need to be configured in order
provide the desired MIMO behavior (
→
'Advanced Wireless LAN
Configuration').
Antennas are only to be attached or changed when the device is
switched off. Mounting or demounting antennas while the device
switched on may cause the destruction of the WLAN module!
When assembling separately purchased mobile radio antennas please
note that the maximum allowed transmission power of the wireless
LAN according to EIRP in the country in question may not be
exceeded. The system operator is responsible for adhering to the
threshold values.
LAN
– First connect the LANCOM Router base station to your LAN or to
an individual PC. For that purpose, plug the included network cable (green
plugs) into the LAN connector of the device
and the other end into a
free network connecting socket of your local network, into a free socket
of a hub/switch or into the network socket of an individual PC.
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 Router
in a network segment at any given time. All unconfigured LANCOM
Router devices use the same IP address (with the final digits '254'),
which would result in an address conflict. To avoid problems, always
configure multiple LANCOM Router devices one at a time, immedi-
ately assigning each device a unique IP address (one that does not
end with '254').

DSL
– connect the WAN interface
to the DSL modem socket using the
supplied DSL connector cable (dark blue plugs).
