2.6.6 Connecting Interface Cable

Caution:

zYou should connect a cable to the port with the correct mark. Misplugging is prone to impair the SIC/MIM and even damage the router.

zYou are recommended to install a special lightning arrester on the input end of the telephone line in order to avoid the lightning effects more efficiently.

If the SIC has been properly installed, follow these steps to connect the cable:

Step 1: Insert the end with ferrite core into one LINE port of Router 1-Port Analog Modem SIC;

Step 2: Plug the other end of the cable into the telephone wall jack;

Step 3: Power on the Router, and check the LEDs of the corresponding slot on the

front panel: ON means that the SIC is operating normally and OFF means that the POST of the SIC has failed. In the latter case, please contact your agent.
