I've been using an APC 1000XL on my home rack for a while now, about 7 years or so at least. When moving I accidentally dropped the UPS on the driveway and tore through the control panel ribbon cable completely... crap.
Without this wire functional the thing was about as useful as an anchor on dry land and just as heavy! I finally tore into it a bit recently and recorded the video. Feel free to listen to me ramble on a bit and tinker.
I'll be uploading more videos in the future, some pertaining to the IT/Linux/Network/Developer things as well. If you guys would like a video on a certain topic please let me know! I'd love some ideas.
