Hi Valery,

I checked the cRIO remotely and couldn’t connect to it. I then went to Hall B and checked it and it looks like something happened with the cRIO and it has a boot error.

It’ll need to be swapped for a spare so I’ll start that process

No, I'll take a look at it and let you know.

Tyler,
I noticed that the nitrogen volume interlock heartbeat is frozen.
Is it normal?
Thanks,
Valery
