The button on the DSQ 3500 Electronics Control Console (EC Console) with the ring of light controls the power to the electronics rack. This light changes colors when the rack is powered up.
The Head Locatization Unit (HLU) power box, on the top of the new rack, has a button with a light within it. Press this button to turn on and off the HLU unit.

There are times that the MEG electronics rack needs to be rebooted.

  • If the Acq starts with some noisy channels, usually restarting the Acq will make the noise go away, if not reboot.
