Can someone help me plz. At my job at a hotel we need to install this equipment. It is to be used as a backup for our servers already in place. My question is that I know nothing about these and as I read up on them I am confused about them. To me them seem to be like a router that takes over when the other systems fail. The thing is that the company wants like $5,000 for the system and so much per month for maintenance fee. I am trying to get around this by purchasing one maybe off of ebay and mantaining it myself. I was wondering if anyone could piont me in the right direction and give me a little education on this. The hotel is small (79 rooms). Thank you so much for you time and help.
