Is there anything useful on Cisco's site, to allow me to configure/upgrade hardware with compatible components, in detail and w/options?
For example - I have right now a 2821 with the 2 built-in Ethernets, and one slot filled with (1) VWIC 2MFT-T1-DI, and (3) WIC-1DSU-T1-V2. I am looking into options of adding 2 (two) more VWIC 2MFT-T1-DI (would that be such a thing as dual module of those?!?), and 2 (two) more WIC-1DSU-T1-V2 (would that be such a thing as module supporting dual of those?!?), and - of course - the "feature" card capable of accommodating the above upgrades (in whicehever shape they would come)
TIA, Papi
