Connect the RS-232 straight-through serial cable between the Console port on the back of the VPN Concentrator and the COM1 or serial port on the console/PC.
If you are using a PC with a browser to manage the VPN Concentrator, be sure the PC is connected to the same private LAN as the VPN Concentrator.
To make the VPN Concentrator operational, you must connect at least two interfaces, usually Ethernet 1 and Ethernet 2.
