Things Judit had to do in the lab to recover after power outage:

  • Shutters - cycled the power using the manual switch on the SHUTTER box in the rack
  • Homed Newport stage VIS beams (same as Esp BC2 gui VISB axis)
  • Bootlaunch_master on ctrscrut to get the BS servers running
  • Homed all 6 Newport BS stages (using guis Esp BS1 and BS2)
  • Labao DM electronics were all fine, all those UPSes kept the power
  • Started up labao computer
  • Pushed power button on the USB hub for labao cameras (on top of the shelf above W1) before starting labao servers so that the servers could find the cameras
  • Labao shutters were OK, on same UPSes as labao DM
  • Cycled ApertureWheels power and inited all 6 Aperture Wheels
  • Started up tiptilt computer → check was forced due to not clean shutdown
  • Soft rebooted tiptilt computer with entering BIOS and RE-SAVED it for proper clock start
  • Homed all axes of tiptilt zabers (ZABER 2) using ENG gui, because they lost their position. [Best to do this when the beams are aligned with labao and corner cubes are in, so that the movements can be seen in tiptilt gui. Laser ND=6. One click on Home button on any axis homes all axes. After homing, for each axes GO TO SETPOS takes it to the latest position in the cfg file. It is likely that the zaber positions need to be adjusted and fresh set positions saved.]
  • All pops were out and PERI positions lost → All 6 PERI axes had to be homed and AFTER THAT set pop5 first with POPPERIGTK and adjusted M10 as needed.

Additional Notes After Power Outage on August, 17, 2021

  • Reinitialize the NIRO Filter Wheel. Open the niro_filter_gtk and click REINIT. Check to see if the indicator wheel on the NIRO camera is pointing to the correct filter after it is homed. Do not turn the wheel by hand. If it points to the wrong filter, home the filter wheel, and compare counts for each filter (or look for metrology light in J-band) to confirm the correct filters are in position. Then loosen the screw on the indicator wheel and align so that it points to the correct filter label.
  • Leave plenty of time to do a full check of the alignment on all beams.
  • Check alignment of MIRC-X and MYSTIC using STS. Make sure the fiber stages and internal delays are consistent with the positions recorded in the manual/headers. All of the MIRC-X and MYSTIC components are on UPS, so they should retain their positions, but it's always good to check in case one of the UPS fails.
