Hi Greg,
What port is the sample changer connected to? If it's on TTY05 then
it's possible the PCI card in the IPSO has failed. The first thing I
would probably try would be to connect the cable from the cryoplatform to
TTY01 on the IPSO and run cf and change the TTY port for the cryoplatform to
TTY01 in cf as well. Then, fingers crossed, you can connect to the
cryoplatform.
Also, if it's passively warming up, you might try just hitting the warmup
button to see if it will warm up actively--if whatever caused the error has
resolved itself then at least you can get the system warmed up so that more
troubleshooting is possible. And then when it's warmed up, if you like,
and if you still haven't re-established communication, you can power cycle
the cryoplatform to see if that gets it back.
If the serial card has failed then it's possible to replace that if it's a
19" IPSO. If it's an AQS IPSO then it might still be possible but those
things require a lot more disassembly to replace that card.
Cheers,Mike

Hello All
Yesterday our AVIII with a helium cold probe had some issue=
s. It was originally reported as a sample changer issue by a user. The system
ran their sample and when they were changing the sample the system error-ed
out with a sample changer error. When we arrived we also noticed the cryo
platform (gen II model I think) was in error and warming. Tried to open
cryopanel and it errors with cannot connect to server. Power cycled everything
in various orders, but no luck. CF indicates that the cryo platform is
connected on the IPSO IP on TTY04 which is correct. We are running Alma 9
for over a year now with Topspin 3.7. We did confirm several services are
still running etc. Any thoughts or suggestions would be greatly appreciated.
Thanks
Greg
