CAUTION:

■You should connect a cable to the port with the correct mark. Misplugging is prone to impair the card and even damage the router.

■When using T1 cable outdoors, you are recommended to install a special lightning arrester on the input end of the cable in order to avoid lightning more effectively.

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

Step 1: Plug one end of T1 cable into the RJ45 connector of FIC-2VT1.

Step 2: Connect the other end of T1 cable to the peer device;

Step 3: Check the status of LINK LED on the FIC-2VT1 panel: OFF means the link is not connected. In the latter case, check the line.
