Installing NM-16A & NM-8 A/S on 2612 and 2651XM Routers. Do you need to configure anything after the installation of modules or they are pretty much plug and play devices.
I thought this is a cheaper option than buying 2511 Acess Router and 2522 Serial Router.
What do you guys think? I already have the 2612 and 2651XM so it'll save me money if i just buy the modules.
