Call the summit, and reach out to the on-duty K2 Instrument Support Tech. Confirm that NIRSPEC is (either) inside AO or back at Right NAS, safely defined with all its lines and connections re-established. You can tell them that you will be doing the post-reconfig powerup checkout, and will let them know when that is done.

This will launch the following GUIs:
motmode pos
init_all_motorsNote 1: This command will not execute if the optical plate is warmer than 69K. Check temps to verify you are in range (from any xterm):
temps
Note 2: When the init_all_motors command is active,
you will see motion to the mechanisms shown in the NIRSPEC
Instrument Control GUI. You will see all GREEN check marks when successfully completed - takes several minutes.
Note 3: It is possible this command will complete quickly (with no errors), which means it has already sensed the need to re-calibrate mechanisms and has already completed this task. You'll see all GREEN check marks in this case.
Note 1: As of April 2022, NIRSPEC has a UPS installed to keep power on the SCAM detector controller throughout the reconfig. So there should be no need to power down and power up the detector controller galil.
Note 2: It is now very unusual for you to need to restart the detector service more than once to get SCAM back to life. In pre-UPS days, initial attempts could've resulted in status = fault, or complaints in the detector dialog about the file not being written. Sometimes, it can help to toggle between full frame and sub-array (i.e. normal mode) SCAM display modes:
scam_fullframe
scam_normal
