<ol>

<div dir="ltr">If the remote reboot does not work, then someone may have to go down and physically unplug and then replug the power cable from the chassis. </div>

<div dir="ltr">If rebooting doesn’t work, then I’m not sure the path forward since we do not have a spare cRIO expansion chassis for RICH S1. </div>

<div dir="ltr">Since there’s still airflows and air pressure for S4, there’s still probably airflow for since the air flow is coming from the same buffer tank and there isn’t a way to change air flow settings for S1 unless someone went and changed the settings
on the physical panel. </div>

<div dir="ltr">I’m away from home now but I’ve been able to look at some of the RICH S1 things remotely. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">I can see that the two air flows, air pressure, and Nitrogen flow for RICH S1 are not updating. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">But, I can also see that the temperatures and humidities are updating for RICH S1. And I can see that there is air pressure and air flow from the buffer tank for S4. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">With this, I think there has been an issue with part of the S1 chassis (specifically the expansion cRIO) that is causing the issue.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">In reality, there is still probably airflow to S1, we just can’t monitor it currently. </div>
