Not relevant if you are using the 40g ports, but on the 4300-32f I ran into an issue using 10g ports - the 4300-f requires you to use the expansion module located on the far left hand side of the chassis for vc. I couldn't get the regular 1/10g module to work and JTAC agreed it requires the expansion module not the uplink module. The 1/10 module does work for Vc ports on the 'T' versions. Just FYI for the group...
