Replacing an FPC
The FPC is hot-removable and hot-insertable. You can remove or replace it without powering down the router and disrupting routing functions. However, you must first take the FPC offline by pressing the FPC offline button on the router craft interface for all router platforms except the M5 and M10 routers.
Action
To return a failed FPC, see Return the Failed Component. To replace an FPC, see the appropriate router hardware guide.
