0. Switch off the agilent camera in the FACT Container
   • open the page 10.0.100.100 from a computer in the internal network of La Palma (can be your computer if you use vpn)
   • push 'Camera Off' to stop the camera (now only 'Bias Power' and '24VDC Interlock Power' should be 'yes')
1. wait for about 15 min
2. switch the agilent on
   • open the page 10.0.100.100 from a computer in the internal network of La Palma
   • push 'Camera On' to start the camera (now all 5 points should be 'yes')
3. make sure that clock-conditioner is locked
4. follow the preparation#startup Start-Up procedure to get the system running again

To check if the clock-conditioner is locked, you may check in the gui in the tab

• 'Trigger' the led next to the pulldown 'DRS sampling frequency'
• 'FAD' with mouse over on the LED next to 'Reference Clock' whether all 40 values are roughly 1/1024
