Robert, Alastair, Dave:

Robert noticed ADC comb noise on a corner station microphone PEM channel. We power cycled the h1oaf0 IO Chassis with the procedure:

• take h1oaf0 out of dolphin fabric (not truely needed, just for insurance)
• powerdown the computer using "powerdown" command in terminal as root
• switch off IOChassis using its front panel switch
• switch on IOChassis using its front panel switch
• switch on computer using its front panel switch

Unfortunately we forgot to tell Alastair his TCS DAC outputs will go to zero volts, which in the case of the chiller setpoints causes laser issues if it is zero for more than 5 minutes. After the front end models were back up and running Alastair recoverted the TCS lasers. I am now starting the effort to write restart instructions to capture these dependencies.

Good news, Robert reports the restart fixed his noise problem.

On a slightly unrelated note, Jeff had installed a new version of h1calcs model which required a DAQ restart.
