The 10GE baseboard ports and the 4 port half cards do not support the TwinGig converter. Only 8 port half cards can support the TwinGig converter.
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6021/ps9310/Data_Sheet_Cat_4900M.html Check under Table 2. This will show the Ports Using Cisco TwinGig Converter Module. We started using media converters for fiber links as I did not want to waste a slot with the expensive 8port half card module.
