Note - you can't use twingig converters in the base 10G ports of a 4900M
- you have to buy the 8-port X2 half-card if you want to use the twingig
converters. 

(you say 10/100/1000 card so I am guessing you intended to use a copper
gig half-card in the first slot.) 

I have a handful of 4900Ms, they work fine pushing fair amounts of
traffic at multi-gig rate (they're in place handling the first-level
uplinks from my TOR 4948-10Gs). I don't do anything terribly fancy with
'em, but they seem as solid as the rest of the 4900s. DOM works nicely
with 12.2(54)SG, finally.
