Open the ASICS LV panel on the TPC-PS rack from the Wiener_MainPanel. You should on-off status for FT 1-11. To turn on or off all ASIC power, enter the "ON/OFF" password ("abc123") and then use the Off or On buttons as indicated. Follow the instructions on the page, and turn on the -3.3V before turning on the +3.3 V. Turn off in the reverse order.
To turn on or off power to a single feedthrough, hit "Open non-expert overview Panel", then hit "Expert Panel" for the feedthrough you want to control. Put in the password when prompted, and then you may turn channels on one by one. Follow the instructions on the page, and turn on the -3.3V before turning on the +3.3 V. Do this for all feedthroughs, and then you can configure the ASICs.
