If all the detectors read out, then everything is working and you are good to proceed with your observations.
ICC Detector Restart
If one or more of the detectors still do not read out or the SCP or DTP freezes, the next step is to try running the detector reset script.
...
Note: Resetting the H-band detector can leave a strong electronic signal on the detector that looks like a bright column. It will slowly fades away over time. Take a 30 second test exposure to see if it is there. You might want to wait 10-20 minutes before continuing observations to allow time for most of the signal to fade away.
Manually Power Cycling the Detectors
If running the detector restart script does not resolve the issue, you will need to power cycle the detector readout electronics controllers. Do the following:
