I have a Catalyst 6509 with Sup720 and have previous SFM capable 48 Port GE Cards. We needed new line modules and budget for SFM wasn't there, so the non SFM line cards were purchased. They were shown as compatible and mixable and now when installed are showing up as unsupported.
9 48 FRU type (0x6003, 0x399(921)) WS-X6148A-GE-TX
%C6KPWR-SP-4-UNSUPPORTED: unsupported module in slot 9, power not allowed: Unknown Card Type
Anyone have any ideas??? Is it an IOS issue?
