Troubleshooting

Procedure for restarting the rack

There are two important power buttons

The button on the electronics console with the ring of light controls the power to the rack. This light changes colors when the rack is powered up.

The 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 rack needs to be rebooted.

• If the Acq starts with some noisy channels, usually restarting the Acq will make the noise go away.
• If the HLU does not work, you must reboot the entire rack.

To restart (reboot) the rack:

1. First you power off the rack. Press the button on the console.
2. Next you must power off the HLU box which is located on top of the new rack. Press it to turn off the HLU.
3. Return to the console and power the rack back on.
4. Wait about 10 seconds.
5. Next, turn the HLU box back on.
6. Now you can launch Acq.
