WP10398 Replace h1iscey front end computer

Erik, Fil, Marc, Dave:

Due to recent spontaneous reboots the h1iscey W2245 front end computer was replaced with the x1lsc0 machine. During the replacement a problem was discovered with the second Adnaco backplane in the IO Chassis, if any card is inserted into its first slot the computer would not boot. The second adnaco bp was disconnected and all the cards from it were moved to the third (previously empty) backplane. When recovering this system we discovered that sw-ey-h1daq was not working correctly. Its ssh server was down, and port 6 would not engage. Following a power cycle of this switch, which caused a disruption of all DAQ traffic from EY and MY to the DAQ, the problem was resolved. See Erik's alog for details.

WP10406 h1omc model change

We installed Jeff's new h1omc model. A DAQ restart was required.

WP10413 h1lsc model change

WP10391 Upgrade of susaux h34 and h56

Dave:

The h1iopsusaux[h34, h56] models had their contec1616 part removed, completing their IO Chassis upgrade. A DAQ restart was required.

DAQ restart

Dave:

The DAQ was restarted for the above model changes. h1daqgds1 needed a second restart to sync its channel list.

Beckhoff SDF upgrade

Daniel, Dave:

The Beckhoff Slow Controls SDF monitor.req files needed to be updated. This required a restart of all these systems (h1sys[cs,ex,ey][aux, isc, tcs]sdf and h1syscssqzsdf). Daniel updated the safe.snap files accordingly.

WP10404 h0vacly upgrade

Patrick, Dave:

The vacuum controls Beckhoff unit h0vacly was imaged and modified to add HAM7 and RT vacuum gauges. Vacuum alarms were bypassed for the duration, and the CP1 fill was delayed until 17:10. A new INI file was generated, requiring a DAQ+EDC restart

DAQ and EDC restart, part deux

Jonathan, Dave:

To complete the h0vacly upgrade.
