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

821/1621 only	ADSL – connect the ADSL interface	to the splitter using the supplied
	ADSL connector cable (transparent plugs).
1711 only	DSL – connect the WAN interface	to the DSL modem socket using the
	supplied DSL connector cable (dark blue plugs).
	ISDN – to connect the LANCOM to the ISDN, plug one end of the supplied
	ISDN connector cable (light blue plugs) in the ISDN/S0 port (LANCOM
	821 ADSL/ISDN and LANCOM 1621 ADSL/ISDN) or			(LANCOM 1711
	VPN) of the router and the other end into an ISDN/S0 multi-device mode
	or point-to-point mode connection.
	Configuration port – you may optionally connect the router directly to
	the serial port (RS-232, V.24) of a PC. Use the cable supplied for this pur-
	pose. Connect the configuration port of the LANCOM			(LANCOM 821
	ADSL/ISDN and LANCOM 1621 ADSL/ISDN) or		(LANCOM 1711 VPN)
	with a free serial port of the PC.

Alternatively you may connect an external modem (analogue or GSM) to the serial port using the LANCOM modem adapter kit, if you would like to make use of an additional WAN line for remote maintenance, backup con- nections or dynamic VPN.

Connect to power – Connect socket	of the unit to a power supply
using the included power adapter.

Use the supplied power supply unit only! Using an unsuitable power supply unit may cause damage or injury.
