WP13110 IO Chassis Timing Card Upgrade

Marc, Erik, Dave:

Today we upgraded the IO Chassis Timing Card firmware, sync ribbon cable and RCG (where needed) on:

Front End Timing Card Firmware Sync Ribbon Cable RGC5.5.2 update
h1psl0 yes yes yes
h1susauxh13 no yes no
h1susauxh2 no yes yes
h1seih16 yes yes yes
h1susauxh56 yes yes yes

There were no issues. DCC doc T2600142 was updated.

WP13163 h1isiham6 build against latest blend_switch_library

Jim, Ibrahim, Erik, Dave:

h1isiham6 was updated to use the latest blend switch library, it was the last ISI HAM model to do so.

We combined this with the upgrade of its IO Chassis, and also rebuilt all of h1seih16's models against RCG5.5.2.

A DAQ restart was required.

Move EDC back to h1susauxb13

Erik, Dave:

Back in Dec 2025 at the start of the upgrades we moved the EDC from what was then susauxb123 so it would not be impacted by the BBSS preparation work.

Now that we have completed the BBSS prep, EDC has come home to what is now called h1susauxb13 (sans BS).

This didn't quite go as smoothly as planned and required several restarts of both DAQ legs before it was correct.

The basic squence was:

1. Erik made the puppet changes such that h1edc would not start on h1susauxh56 but would do so on h1susauxb13.

2. Following the upgrade of h1susauxh56's IO Chassis, we powered this up to verify no edc on it.

3. We then hand restarted edc on susauxb13, then started the DAQ 0leg. We had DAQ errors at this point.

4. After a reboot of susauxb13 we found the issue, the daq receiver was not being restarted on DC0, just the daqd service. One DC0 was restarted this way, it had a good edc status. Unfortunately it started not quite in sequence and a clean 0-leg restart later got all the delta-times positive.

5. Restarting the 1leg went a bit better, but NDS1 did not restart cleanly and needed a manual start.

h1susauxh56 is now ready for its BHD upgrade with no impact on EDC trending.

DAQ Restart

Erik, Dave:

As mentioned above this was quite a messy start due to the move of EDC to susauxb13. The EDC INI was also changed to add the non-RGC FEC/SDF channels for the new models started in the past week (spih23, suslo12, susauxh6).

The h1isiham6 ini was also part of this DAQ restart to add the +12 STS GND channels.
