III. Installing SIC
Follow these steps to install a SIC:
Step 1: Place the rear panel of the Router towards you;
Step 2: Turn off the power switch of the Router and unplug the power cord;
Step 3: Take out the SIC and align its remote edge with the edge of the slot on the
Router’s rear panel;
Step 4: Push the SIC into the Router until it closely mates with the rear panel of the
Router;
Step 5: Fasten the SIC into the Router with captive screws;
Step 6: Power on the Router, and check the LEDs of the corresponding slot on the
front panel: after the initialization of the SIC, ON means that the SIC is operating
normally and OFF means that its Power-On Self-Test (POST) has failed. In the latter
case, please contact your agent.
