This morning the DMS reported a failure of the laser chiller that triggered the laser over temperature protection. Upon investigation, we found that the chiller indeed needs servicing, since it seems it is not cooling the water anymore. Note that it does not show any failure error.
Since the spare chiller is still being serviced (will be back next week), we managed to re-install an old Virgo+ laser chiller, intentionally left in the intercapedine for emergency.
The old server has been restarted, the correspondign process is running on the VPM and there is a working flag on the DMS.
The CO2 laser also has been restarted and seems to be working fine.
