In preparation for NAOJ blackout, I completely shutdown all filter cavity related electronics.

All cleanroom equipment - lasers, NIM racks, photodetector power supplies, measurement instruments, computer, homodyne PSU, AOM RF amplifier PSU, rack RF amplifier PSU, filter fan. Then I switched off the power at the cluster behind PR/IMC_IN, which is the cleanroom main power.

External equipment - all oplev lasers, PD/QPD, coil drivers and pico controllers (PR, BS, IN, END), SR560, NIM racks, ADC, camera adapters, workstation, monitor, air conditioning main control
