Great explanation – thank you!
I have one question, we have a lot of ISR routers with PVDM2′s already installed. If we want to upgrade to the ISR G2′s (2900, 3900) is there someway we can use those or do we have to buy PVDM3′s?

Hi Neil,
The PVDM2s are made for the ISR routers (28/3800 series) and will not work “natively” on the 29/3900 series. But if you already own the PVDM2′s and simply want to upgrade the ISRs to ISR2s (in your case) you can do this with an adapter. The PVDM2s will plug into the adapter and the adapter will plug into the 29/3900 ISR2. This way you can leverage your current investment in PVDM2s.
Thanks,
Michael
