Hi Tyler,
<div class=""><br class="">
</div>
<div class="">The switch has been replaced, and it looks like the N2 cRio EPICS hearbeat is still not alive and so in alarm state.

<div class="">Hi Nathan and Sergei,</div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class="">I saw that all three RICH hardware interlock cRIOs had stopped communicating over the network around 4:30am. </div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class="">Since all three went down at the same time, I suspected a power issue, but when I went down to the hall just now, all three were running fine. </div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class="">I then noticed that network switch “hallb-c3-4-sw” that the three systems are connected to did not have any of its traffic indicator lights blinking. </div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class="">Do you all know of any network outages or other issues with that switch?</div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class=""><br class="">
</div>
<div dir="ltr" class="">Also, as an aside for RICH collaborators, both sectors are still getting 40 slm of nitrogen, so I am confident that the humidity in both sectors is still low despite not currently being able to remotely see the data. </div>
