    Iv recently purchased a couple of router and switches and all that i would recommend is that you ask them to send you a show version. I purchased a 2611xm from ebay and when it arrived it was just a 2611 so the rest i have bough i got them to send me a show version before.

    I think this is a tuff one to answer in a short simple post. It also doesn’t help that you don’t know much about Cisco switches and routers.
    If you are buying from someone whom you meet on craigslist, that makes it harder to test out in a public environment. When I bought my (4) 2950 from a guy off of craigslist, I truly was hoping that at least two of them worked perfectly… lol
    It’s when you get home that you can test them out, but again, since you are new to it. It is going to be a learning process for you.

    Fortunately Cisco switches are NOT junk and they work for the most part, but things can go wrong such as having a bad port or won’t post.

    Ask port POST results

    show version
    sh inventory
    sh environment

    I'd say these three should give you most of the relevant information.

    If you can't power the switches on and you're can literally just take a look at it's externals. I would just do some basic things such as checking for damage, make sure it generally looks in good condition and not many signs of loads of use.
