We turned off the HV bypass for upcoming HAM7 work. The power is located in the racks on the Mezannine in the Mechanical Room.
I followed Fil's instruction by first turning off the 24V for the interlock chassis, followed by removal of the bypass from the interlock chassis and then switching off the SQZ_PZT power. Finally I switched off the SQZ_TTFSS power, so that all high voltage is off.
