[c-nsp] Cisco 4900M onboard X2 and twingig convertors

[Sam Stickland]

Hi,

Is anyone able to confirm whether the onboard X2 slots on the 4900M 
support the twin-gig modules?

Some of the documentation suggests they are only supported on the 8-Port 
(2:1) 10 Gigabit Ethernet (X2) Half Card, but I haven't seen any that 
definitively rules out there use on the onboard slots.

Thanks,

Sam
