But beforethat, you must first execute the remove slot command; otherwise, unknownerrors might occur. When you replace the removed FICs, you do not need toexecute the undo remove slot command however.If you execute the remove slot command inadvertently, you can cancel thatoperation by using the undo remove slot command.Tools required■ ESD-preventive wrist strapRemoving a FICStep 1: Place the router with the front panel forward.Step 2: Remove the cables connected to the FIC.Step 3: Loosen the captive screws at both sides of the FIC.Step 4: Push the ejector levers at both sides of the FIC outward, pull the FIC out ofthe slot along the guides until disengaging it totally from the slot.Installing a FICStep 1: Place the router with the front panel forward.Step 2: Align the remote edge of the FIC with the slot edge, push it into the slot,push the ejector levers inward until it presses against the FIC panel (the anglesthus formed between the FIC panel and the levers are the minimum angles).Step 3: Fix the FIC in the chassis by fastening the captive screws.Repeat these steps to install all the other FICs.Troubleshooting H3C Series Routers provide LEDs, thus facilitating you to make sure whether aSIC/MIM/FIC is properly installed by viewing their state as follows:After the installation of a SIC/MIM/FIC, turn on the power and view thecorresponding LEDs on the cover of the Router chassis: ON means that theSIC/MIM/FIC is operating normally and OFF means that the Power-On Self-Test(POST) of the SIC/MIM/FIC has failed.If the installed SIC/MIM/FIC is in abnormal state, check that:■ Proper interface cable is used;■ The LEDs on the panel of SIC/MIM/FIC are displaying normally (see the sectionintroducing the SIC/MIM/FIC for its LED status and description);■ The SIC/MIM/FIC accepts the configuration and works well using the displaycommand.
