Hello, first post here!
I'm working on my CCNA, and buying new hardware is addicting! I'm scouring the auctions daily for good deals/equipment I wish I could buy if I had money

I happened to pick up two routers that have an NM-1A-OC3MM. I've briefly read some short documentation on it, but is there anything I can do with them? Will they come in handy during studying for CCNA/CCNP/CCIE/??
