We turned off the HV bypass for upcoming HAM7 pump down.  The power is located in the racks on the Mezannine in the Mechanical Room.

We 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.

We reconnected the pressure sensor while we were there in place of the bypass.
