4. Hardware Installation:
Prepare your Internet information, and then follow the steps below to install your IPF-2002L.
※ For the Cable ISP subscriber:
Cable ISPs usually provide DHCP to its subscribers, and each time they only allow one user
to logon. Therefore, most ISPs require their subscribers report the MAC address of their
internet device to allow them to use the service. If you want to apply another account for
IPF-2002L, just simply report the MAC address of your IPF-2002L to your ISP provider.
If you want to use multiple internet devices in the same time, you need a router to connect to the
ISP, and connect your internet devices to the router. Then replace the original MAC address to
your router’s MAC address.
4.1 Connection with a Router
Plug one end of the RJ-45 cable to one of the LAN port on the IPF-2002L, and plug another end
to one of the LAN port of your router. Once “Ready for call” is shown on the screen, the
hardware installation is completed. There is another LAN port available for you to connect to
another internet device or to your PC.

IPF-2002LUser Manual

4.2 Connection without a Router
Plug one end of the RJ-45 cable to one of the LAN port on IPF-2002L, and plug another end to
one of the LAN port of your HUB. Once “Ready for call” is shown on the screen, the hardware
installation is completed. There is another LAN port available for you to connect to another
internet device or to your PC.
