    Replace the SFM

    The SFMs are hot-removable and hot-insertable. You can remove and replace SFMs without powering down the router or disrupting the routing functions. However, you must take an SFM offline before replacing it.

    Inserting or removing an SFM causes a brief interruption in forwarding performance (about 500 ms) as the Packet Forwarding Engine reconfigures the distribution of packets across the remaining SFMs.

    To replace an SFM, see Return the Failed Component or the procedure to return a field-replaceable unit in the M40e or M160 router hardware guide.
