<div class="">If it's not too late, I'd be in support of increasing the PDU quantity a bit (or adding another PR). Maybe something closer to the number of cRios in Hall B (that are too far from others to share a PDU). What would that number be? I suspect
it's not a big expense and probably worthwhile, as I think we've seen these cRios occasionally need a reboot and these PDUs can come in handy in the future for other devices nearby (each socket is independently controllable).</div>

Yes, I think it would be helpful to put the cRIOs on something that lets them be rebooted remotely if they aren't available on the network.</div>
