[c-nsp] WS-6500-SFM insertion into production box, much of an impact?

[Rubens Kuhl]

Remember that full SFM usage requires all modules to be
fabric-enabled. If there are any line cards that aren't fabric
enabled, all traffic will still go thru the bus, doesn't matter if it
is an OIR or from power-up.

Your question is if this OIR stands for Online Insertion and Removal
or for Online Insertion and Reboot... although I don't know the
answer, what I saw over the years is that even if it doesn't require a
reboot, you will want to do one, because any issues will have after
that will make you wonder whether if it's due to OIR or not, so you
will end up rebooting anyway.

So, reboot while you have a planned window to do so, not when you are
under pressure.
