I have had this issue for a couple weeks now. I made another post about it thinking I had solved the problem but I haven’t. Background is that I have been running this system for about a year and a half. The last half year I have been running 12 DC-125s plus console. All this issue started when the ATI Firepro 2270 Video card’s heat sink warped making the card overheat and quit. I have since replaced the video card.
I have 12 DC-125s and one Console. I can plug in 11 DC-125s with Console but when I plug in the 12th one, a different DC-125 quits and the newly plugged in DC-125 works. When I unplug the 12th one, the one that quits starts working.
No matter which DC-125 I pick to plug in last, it will always take out one of the other DC-125s to work.
I am beside myself trying to figure out this issue. I have also ran the displaylink tool and have it if you would like. I didn’t really know where to look to determine the issue. I ran the tool with 12 DC-125s plugged in plus console.
Just a note, the console is USB plugged into a hub. That hub is plugged into root on the server. Everything else is behind one or two hubs.
I know you guys are phenomenal to help. Any ideas? Thank you so much!
