H2 maintenance day

About 50% of the H2 front ends were upgraded to RCG 2.5.1 last week, this week I cleanly rebuilt and restarted all H2 frontends against 2.5.1 in conjuction with the timing change.

All of H2's timing signals were moved from the old h2 timing master to the new h1 timing master. The old h2 timing master is being decommissioned.

errors in the burt restore of the safe.snap files were seen on h2peml0, h2tcsitmy and h2pemey (my problem, I'll fix these).

Problems with a large ADC input on h2hpietmy is being tracked to a HEPI pump issue at EY.

The 24MHz RF amplifier at EY is showing a timing problem on the fanout, and its fpga led is blinking red sometimes.
