Regarding the SUP1A module, I have been reading that if the SUP1A comes with only a PFC installed, you can't install a MSFC or MSFC2 on it. However, if the SUP1A comes with a MSFC, then you can install a MSFC or MSFC2. Why is this?
The reason why I am asking this is because I ran across this. IS this a way for Cisco to make you buys a SUP1A with a MSFC?
