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.
