Dear All,
we are hoping for some input from the community to fix these issues.
After a reboot of the Mercury (computer and console; running VJ 4.1?) we
noticed the junction board was beeping, red light for beeper was on, the
rest of lights were off; no communication could be established between the
console and PC; su acproc failed to connect.
We first replaced the junction board with one from a different console but
got the same error.
Trouble shooting with the help of Simon Sham revealed that their Mercury
had had similar issues and it was fixed by exchanging the power supply.
We installed a power supply from a different console. Now the console came
up quiet but acquisition was inactive even though voltages from the power
supply seemed ok. After reboot of the computer, an error light showed up on
the two connected boards on the left side of the console (APTO red, FFMT
orange).
We proceeded to exchange these boards for ones from the other console. We
could now get a connection to the computer but no RF power to the
spectrometer. After a short time the console went back to beeping and the
red error light on the junction board was back on.
We then tried all permutations of the 2 junction boards and the 4 other
boards (from both consoles) but eventually got the same error lights and
either no connection to the PC or if we had a connection we did not have RF
output.
Thinking the problem might be the backplane, we then put all the correct
boards back into the other console and moved that whole console (which had
been functional prior to us removing the boards) to the spectrometer and
connected it.
After a reboot we got all the same error lights on the 2 connected boards
as well as the junction board. The beeper is on.
At this point we are stuck and not quite sure how to proceed. Any
suggestions are welcome!!
Regards,
Heike
