Note: Rosalie will warm the detector by 5 deg C the day before. Normal operation temps are blue -110.1 deg C (163 K) and red -125.0 deg C.
Without a UPS: run the kcwiPowerDown script (same as if we were installing or removing KCWI from the telescope). On k2-insttech (vm-k2obs:2), from the background menu → KCWI Control → KCWI Engineering → Power Down KCWI. Answer any required questions and watch to make sure it is powered down successfully.
MORE PROBLEMS THEN I GUESSED, THE UPS SECTION NEEDS TO BE MODIFIED TO HAVE A “KCWI START KRDS” AFTER POWER IS SWITCHED TO THE UPS, BECAUSE THE CONTROLLER DOESN’T KNOW WHAT TEMP TO MAINTAIN WITHOUT SETTINGS SENT FROM KCWISERVER ONCE.
With a UPS:
With comms: Immediately prior to power down, summit techs should open an
xterm@kcwiserverfrom the k2-insttech (vm-k2obs:2) background menu, and typekcwiOutagePowerDown "off"to run the script to shut most of KCWI down, leaving on the Blue Lakeshore (blue temp control), the Red detector (red temp control), blue and red ion pumps (pressure control), and the lantronix (comms with ion pumps).Manually:

Go up to KCWI and physically switch to UPS power. Open the electronics cabinet door and position a Tall Ladder for access.
Physically turn on Eaton 1 (green Power light should light up) and turn on plug 4, a (orange?) light should show over the 4. This is the Blue Lakeshore / blue detector heater. Turn on the Blue Lakeshore if it doesn’t turn on automatically. It should monitor and control the temp of channel 1 (blue detector) automatically.
Physically turn on Eaton 2 (green Power light should light up) and turn on plug 3, a (orange?) light should show over the 3. This is the Red detector controller/heater. It should turn itself on.
Check the UPS. If time/voltage draw looks reasonable (>2 hrs power remaining), we want to turn on the ion pumps.
Physically turn on plugs 6 on BOTH Eaton 1 and 2.
Climb the Tall Ladder to the Very Top of the electronics cabinet to access the Ion Pumps.
For BOTH BLUE AND RED: Press the blue power button (bottom left corner) and see the power light come on.
For BOTH BLUE AND RED: Once powered up, Press and HOLD the red HV (high voltage) button in the upper left corner until the light comes on and the display shows pressures, likely around 2-4e-6 torr.
Ion pumps look like this, although you will only see the screen:
If on UPS power, leave electronics cabinet door OPEN.
