Relatively painless start-up. Had an issue with firefox where all bookmarks had been forgotten.
All drop down menues in the DAQ did not work.
Kill all firefox processes to restore.

Had to restart DHCP to get the rasp pi working again.

At first no pulser was visible in all p-side FEEs. Cable and BNC adapter on output of inverter were switched out
and the inverter output
was switched from B to A.

After this pulser signals were visible in all ASICS bar NNAIDA 14 ASIC 1. Power cycle was needed to regain this.
No ADC data and no fast discriminator data. Waveform showed baseline at 16K compared to 8K expected.

Layouts 1,2,3,4,7 and 8 attached (Zoomed in waveforms are included for 7 and 8 around baseline) attachments 1-8

Temperatures included as attachment 9

Leakages and bias all ok see attachment 10
Ambient T 24.3C Humidity 34.5% Dew point 7.6C (Measurements taken AM)

system wide checks all ok.
