Remove FIC Use the following procedure to remove a FIC
1 Issue command to remove FIC.
2 Place the Router with the front panel forward.
3 Remove the cables connected to the FIC.
4 Loosen the captive screws at both sides of the FIC.
5 Pull the ejector levers at both sides of the FIC outward, pull the FIC out of the slot
along the guides until disengaging it totally from the slot.
Install FIC Use the following procedure to install a FIC.
1 Place the Router with the front panel forward.
2 Align the remote edge of the FIC with the slot edge, push it into the slot, pull the
ejector levers inward until it presses against the FIC panel (the angles thus formed
between the FIC panel and the levers are the minimum angles).
3 Fix the FIC in the chassis by fastening the captive screws.
4 Repeat these steps to install all the other FICs.
Troubleshooting The 6000 FICs have LEDs for status reporting. Generally, you can locate the
problem by performing the following operations if an FIC is not working normally.
■
Check the interface cables, making sure that you have used the correct cables.
■
View the LEDs on the FIC panel, ensuring that the FIC is working normally.
■
Executing the configured display command, ensuring that the interface has
accepted the configuration and is working normally.
■
If anomalies occur without executing the remove slot command, you can
perform the following operation.
■
Restart the router (sometimes the router automatically restarts), and check if
the problem has been solved.
