At my workplace they're trying to extend network infrastructure and confused over PoE and Non-PoE switches/routers. They want to opt for Non-PoE ones over PoE ones on cost grounds. Can some network techies please advise what alternative Non-PoE switches/routers are out there to replace C3750E(S) or C3650E(S) advised by the cisco agents? How much will we be better off in terms of total cost? Which are the best ones? Your advise will be highly appreciated!
