Hi Dan,
Well, that problem sounds familiar- last week I had a user complain of the same issues with our 4 year old VNMRS console (your colleague forgot to mention what vintage Agilent console the problem was occurring on) and rebooting the master the next morning took about two hours for all the controller boards to "dance" properly. I posted this problem over at the Spinsights community and there is a shell script that can be run to test the Ethernet communications amongst all the controllers. Mine tested all fine (although I ran the test after the console appeared to be fully idle). Since that occurrence, the spectrometer has run 3D's for the last six days without issue. The +5V which supplies the card cage is a little low on mine ~4.85V), so perhaps it is on the edge and had dipped further when the issues were occurring? Otherwise.....gremlins?

Hello Folks,
A colleague has a problem with an Agilent 600 console.
I'll copy his notes below. Any help will be appreciated.
Dan
The first hint of a possible problem came yesterday morning with the spectrometer being unresponsive accompanied by an "ACode Error." An RF card-cage reset, via its Master Board, appeared to solve that problem, and the instrument worked fine through late this afternoon. However, when I tried to begin with the next sample, I noticed that a "Set Up Parameters" command ("su") failed, and the system went into an "Inactive" mode. Master Board resets appeared to briefly return the system to "Idle," but it would suddenly turn back to "Inactive" without issuing any other commands. I then notice that the scrolling LED's displays on the RF boards were no longer showing their regular displays, and they eventually failed to give any "patterns" together. The card cage's power supply was indicating that all its DC Voltages were present with green panel lights, but I wasn't able to check test points with a multimeter. As I mentioned above, none of the other obvious power-cycles proved useful.
