CDS Maintenance Summary

WP7716 Revert SUS QUAD models to reduce number of violin mode damping filters.

Jeff K, Dave:

All four SUS quad models were restarted, the recent addition of extra violin mode damping filters was reverted. DAQ restart was needed.

Fixed ADC channel bug in h1pemcs

Dave:

I fixed the ESD voltage monitor channels in h1pemcs and restarted the model. DAQ restart was not needed.

Guardian ISI_HAM3 node restarted after lock file removed

TJ, Dave:

We removed a lock file which was preventing GRD ISI_HAM3 from restarting.

h1seih23 IO Chassis power cycle to hard reset BIO card

Hugh, Dave:

We power cycled h1seih23 (cpu and IO Chassis) in order to hard reset of the Contec 64/64 binary IO card. This is part of the watchdog tripping investigation when digital/analog filters are switched. Looks like it did not improve the situation.

The power up sequence as defined in T1600332 was followed (https://dcc.ligo.org/LIGO-T1600332)
