CDS Maintenance Summary: Tuesday 10th September 2024

WP12069 New CDS NAT router test

Jonathan:

The new CDS NAT router was tested successfully. It has been left in place as the production machine. Details in Jonathan's alog.

WP12067 Add PEM ADC to h1iscey

Fil, Erik, Dave:

The additional PEM ADC was added to h1iscey's IO Chassis. At the same time the failed A2 Adnaco backplane in the chassis was investigated.

After replacing backplanes and swapping fibers the problem was traced to the Adnaco adapter card in the front end computer, specifically the PCIe slot it was in (slot7, left-most as viewed from rear of computer).

h1iscey does not have any Contec binary IO cards, so it was possible to skip PCIe-slot7 and temporarily only use three Adnaco adapter cards.

h1iopiscey model was modified to add the new ADC. A DAQ restart was required

WP12076 Add VACSTAT EPICS channels to DAQ

Dave:

A new H1EPICS_VACSTAT.ini was added to the DAQ. EDC+DAQ restart required.

WP12075 Add RACCESS UID EPICS channels to DAQ

Dave:

H1EPICS_RACCESS.ini was expanded to add the UID channels. EDC+DAQ restart required.

WP12059 Add CDS HW Status EPICS channels to DAQ

Dave:

H1EPICS_CDSHWSTAT.ini was added to the DAQ. DAQ+EDC restart required.

DAQ Restart

Dave:

The DAQ was restarted 12:01 0-leg, 12:05 1-leg for the above changes. EDC was restarted at 12:02.

No problems with the restart, no second GDS restarts were required.

h1digivideo3 cameras briefly offline

Dave:

While tracing the digital video servers ethernet cabling I discovered the WorkStation-VLAN ethernet cable in eth0 of h1digivideo3 was not fully seated and its cameras went blue-screen.

After Erik alerted me to the issue, I pushed the ethernet cable and it reseated with a satisfying snap and the images started streaming again.
