Another occurance this afternoon of a h1lsc0 timing glitch while there was activity in the CER. As before, the IOChassis itself was not impacted, only its timing slave unit which is independently powered. I restarted all the models on h1lsc0 and h1oaf1 (OAF1 tripped because it is timing slave to LSC). Sequence was: stop all LSC models, stop all OAF1 models, start all LSC models, start all OAF1 models.

I then reset the DIAGs on all front ends, cleared the DAQ CRC counters. Within a few minutes the CW hardware injection restarted, all is now GREEN.
