Hello,
Have been having trouble with the AQS rack on my older AV2 600. Things were
okay but had been looking into another problem. Decided to power down then
on the AQS rack and has not worked since.
Main thing I see is an error when trying to use Unitool to communicate with
the AQS. The error is:
ERROR B219 from AQS: initialization is still in progress. Last message
ignored. Try later again!
I can telnet to spect, launch Top spin but there does not seem to be a way
I can remember around this. It is as if all the blinking on the CCU is a
constant attempt to keep initializing the AQS setup. Power supplies, fans
and other likely suspects are okay. Also tried removing some boards thinking
they may hold up the initialization.
Any ideas?
Thanks,
Mike
