We have got Cat6509 switch with Sup720 and 12.2(17a)SX IOS. There are already two WS-F6748-DFC3B blades in this switch working absolutely fine. We have got a new WS-F6748-CFC blade and have plugged it in slot 3. In "show module" the new card is present and the "power module 3" command was accepted. But the card does not get any power at all and "show power module 3" command reports that the blade is plugged in, its administrative status is up but its power status is down (in brackets it also says "not supported"). Does anybody know if we are supposed to do something different to make the switch to provide power for the 6748-CFC blade?
