Thre are two maxnet controllers that control the QWP motors. They are named polhemaxnet (this is in the same rack as the coil power supplies) and polhemaxnet2 (this is in the rack below the pivot). If you believe one of them is no longer responding, try pinging them with 'ping polhemaxnet' (or 'ping polhemaxnet2'). If it does not respond, it likely needs to be reset.
polhemaxnet is on hcreboot5 and polhemaxnet2 is on hcreboot6. Follow the instructions on those pages to power cycle the controller that is hung up.
After the controller has been rebooted, the software needs to be restarted by logging into the raspberry pi that runs the IOC.
First log onto the pi with 'ssh pi@polhe3pi2'
For good measure, kill the process for the rebooted controller first (in case it didnt close properly)
For the Transverse and Longitudinal 1 polarizers, use 'killall polarizers_2' For the longitudinal 2 polarizers use 'killall polarizers_secondSet'
Finally run './startProc' to start the software
Once the software is restarted, the stages will need to be homed again before use.
