The EQB1_DBOX_03  was found in timing_errorc since 06h48m_UTC (see the attached plot), usually this occurred dutrng each maintenance period . 

The recovery was performed between 2026-10-09-10h41m16-UTC and 2026-10-09-10h43m45-UTC.

Below the details of the procedure to perform to recover the correct running confitions

Fom this VirgoOnline VPM window 

• remove the SQ1_dbox_rack server from the FbsDet server 
• stop the  EQB1_HD_CC server 
• from the SQB1_dbox_rack server
  • re-configure the full EQB1_DBOX_03 dbox board 
    • in the DMS interface, the Daq_EER_DBOX3_timing_error  flag shoud be green but the  EQB1_HD_CC_DAC_ssfs_flags  and the  SQZ_CC_DAC_ssfs_flags are red now
  • then re-configure the  EQB1_HD_CC_DAC  FAST_DAC mezzanine 
• restart the  EQB1_HD_CC server 
  • in the DMS interface, the  EQB1_HD_CC_DAC_ssfs_flags  shoud be green

As there is some signals from the  EQB1_DEMOD_03  demodulation mezzanine sent the SQZ coherent control FAST_DAC mezzanine, this one has to be re-synchronized.

From this VirgoOnline VPM window 

• stop the  SQZ_CC_Ctrl server
• from the SQZ_DBOX_DET_EERoom server
  • re-configure the  SQZ_CC_DAC FAST_DAC mezzanine
• restart the  SQZ_CC_Ctrl server
  • in the DMS interface, the  SQZ_CC_DAC_ssfs_flags  shoud be green
• perform  the reloadConfig of FbsDet server to restore the SMS data collection of the SQB1_dbox_rack server
