The MSR 50 series supports hot swapping. Thus, you can remove or install FICs
when the router is running without disconnecting the power supply. But before
that, you must first execute the remove slot command; otherwise, unknown
errors might occur. When you replace the removed FICs, you do not need to
execute the undo remove slot command however.
If you execute the remove slot command inadvertently, you can cancel that
operation by using the undo remove slot command.
Tools required
■ ESD-preventive wrist strap
Removing a FIC
Step 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 of
the slot along the guides until disengaging it totally from the slot.
Installing a FIC
Step 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 angles
thus 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 a
SIC/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 the
corresponding LEDs on the cover of the Router chassis: ON means that the
SIC/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 section
introducing the SIC/MIM/FIC for its LED status and description);
■ The SIC/MIM/FIC accepts the configuration and works well using the display
command.
