Recovery from power outage

Richard powered up h1seih23 from the front panel, it is now running.

We power cycled h1psl0, it is back.

Erik reconfigured EX Dolphin front ends to communicate with port 8 of the EY Dolphin switch to get them to get the models going. CDSRFM at EX points to port 7 of EY's switch.

All models are running, only IPC errors are long-range-dolphin.

Should someone from operations start activating the SEI and SUS systems?

After the power outage, I went out to the site ~10pm Pacific to check status of purge air skid. Kobelco, water pump and drying towers were all running upon arrival. I verified the dew point was still ok (-41.8C measured at HAM1) and verified the drying towers switched normally. Note: Purge air was only connected to HAM1 since doors are off, corner volume is vented but not actively purging with no doors off.

While there I also restarted the controller for 3 of the FCT ion pumps and reset solenoid valve on aux cart connected to GV5 annulus. All looks ok. Left site ~10:40pm.

Regarding the 4UHV ion pump controller, the autostart setting is enabled now, thus the unit should power ON after a power glitch.  See some of the instructions to access the general menu.
