I had mentioned a couple of days ago about the batteries in the UPS for the security system at work. Well I changed them tonight, took all of 15 minutes, everything connected got rebooted. So in the end I had 5 or 6 cameras not working. The DVR showed their status as connected. I rebooted the DVR a few times and got the same. I remotely connected using my laptop and could view all the missing cameras as well as play back recorded video.
So while I couldn't see why rebooting a couple switches would do any good since I could see the cameras worked when connected remotely but decided to try it as it couldn't hurt.
Both switches are POE BTW. Well I got back to my "office" and there they were on the screen that's connected to the DVR. Hey, this is what I do everyday, it about got away from me. I was getting ready to ask for help.....right here in this thread.
