•Replace an FPC in an M40 Router

•
•	On an M40 router, the FPCs are hot-insertable and hot-removable, so you can remove and
•	replace them without powering down the router. When you remove an FPC, the router
•	continues to function, but the PICs installed on the FPC do not receive or transmit data.
•
•	For instructions, see the following sections:

•Remove an FPC from an M40 Router

•
•	The FPCs on an M40 router are located on the front of the chassis below the craft interface.
•	Each FPC, fully configured with four PICs, weighs about 3 lbs (1.5 kg).
•
•	To remove an FPC from an M40 router, follow this procedure:
•
•	1. Place an antistatic foam mat on a flat, stable surface to receive the FPC. If a foam mat is
•	not available, substitute a standard flat antistatic mat but use extra care when laying the
•	FPC on it to avoid damaging the electrical components. If any of the PICs on the FPC use
•	fiber-optic cable, also have ready a rubber safety cap for each transceiver and cable.
•
•	2. Attach an ESD wrist strap to your bare wrist and connect the strap to one of the ESD
•	points on the chassis.
•
•	3. Label the cables connected to each PIC on the FPC so that you can reconnect each cable
•	to the correct PIC.
