I'm also looking for the same information. I'm not sure if you've seen it but a
member of the forum (liviu.gheorghe) gave me the link below:
http://www.cisco.com/warp/public/cc/so/neso/vvda/iptl/5nine_wp.pdf
It was very useful but it did not contain most of the information that I needed.
Information about the MTBF of the 6500 and some modules were provided
but I think a complete list for all of the modules doesn't exist at CCO.
I would be very glad if somebody out there knows if it exists or not,
and if it does, where?
