My company moved offices across the country and I have inherited 4 AP121 devices. A couple of them look like they were previously used but a couple are new-in-box. I would really like to utilize them but after looking around in the community and connecting through putty, I am a bit stumped. Do I need a current Aerohive subscription of some sort to be able to use these? I am perplexed at how to access the HiveManager GUI and cannot login as a previous IT consultant must have purchased these so I don't have an account to access. Please help or let me know if these are just paperweights at this point. Thanks.
