Hi
The telecoms have 12006 GSR, and need to upgrade to 10gig module with new
SFC and CFC cards. I need to make sure that existing cards will work with
the new CFC/SFC or do I need to remove the CFC/SFC before I plug the new
cards.
If anyone knows a guide documentation on this, also I can't do a much trial
and error as it's a LIVE environment, and the client is a major telecom
Regards,
