woops, sent the email too quickly.... here you go... normally one would consider TTM, however in this case, the upgrade fixes bugs and solves technology issues. there might not be heavy TTM considerations, but there are 10/100/1000 TTM considerations to make. you may realize that 1-3 years down the road you will be replacing 6148 modules with Cat6k modules (not currently available except on the Cat 4000, 3550, and 2950 platforms) that do 10/100/1000 (obviously copper). this should be calculated as a hard cost when doing returns-based investment for cisco gear. you should also consider the support costs and upgrade conditions, as well as many other soft costs for proper ROI. fortunately, for the Cat6k platform, you don't pay for anything support-wise besides the chassis, power supplies, and OSM modules (if you have any). I believe that Cisco also charges support on some fabric-enabled LC's, in particular - 16-port Gigabit Ethernet modules. You may see Cisco (as with other vendors) charge per LC on high-end platforms like the Cat6k, especially when feature-rich vs. feature-free modules are concerned.
