I'm looking at the datasheet for the WS-X6708-10G-3C at this link:
It says that the Supervisor 720 is supported, but doesn't give any specifics. I have a Supervisor 720 with a PFC-3A. Am I correct in thinking that you cannot run the X6708-10G-3C without a PFC-3C?
Second question - in order to get to the PFC-3C, am I correct in thinking that there is not an upgrade path? Basically, we need to replace the Supervisor 720 (PFC3A) with a VS-S720-10G-3C?
