another h1oaf0 DAC error at 14:02 PST

Another event at 14:02 PST , proc status file for IOP model posted below.

If this is a timing error (and at this point we are not certain of this), our first change was to replace the fiber optics cable between the IO Chassis timing slave and the timing fanout chassis. A new cable was installed before the system was restarted.

Note, the existing fiber was found to be not cable tied to the bundle of fibers at the timing fan-out card, rather was floating by itself.

Sequence was:

* we did not do the TCS-AI power sequence this time and unfortunately this may have tripped the TCS chillers.

From Dave's above alog: "* we did not do the TCS-AI power sequence this time and unfortunately this may have tripped the TCS chillers."

This unfortunately did trip the TCS chillers and therefore the TCS CO2 lasers.  I reset them all around14:30 PST; everything came up without issue.
