Power cycle procedure for camera/USB fiber extender
NOTE: This may not be necessary if one uses Dan's ~ddamiani/reset_andor.sh script described below.
Occasionally after power cycling the camera or everything if there was a power outage the USB fiber extender will come back in a bad state where it won't communicate with the camera. One time we saw these errors in /var/log/messages when the VLS camera broke:
...
- Power off the camera (NOTE: to do this I believe you have unplug the power supply, since the power supply just has a rocker switch which I think selects between standard-cooling/deep-cooling?). The only LED that gives any indication of power is a green one inside the power supply, visible only if you put your eye somewhere near the deep-cooling ("||") side of the rocker switch at a specific angle.
- Power off the camera side of the extender
- Unplug the server-side extender USB cable from daq-rix-andor-01. The DIR andor extender has the black USB cable (top USB port) and the VLS andor extender is the silver cable (bottom USB port).
- Re-plug the server-side extender USB cable into daq-rix-andor-01.
- Power on the camera side of the extender. You should see the link led turn on on the extender, and the host led blink slowly.
- Power on the camera. The host led on the camera side extender show turn on solid now, and the activity led should blink intermittently.
- Restart the IOC (the existing IOC process my be locked up and may need to be kill -9 to die) or alternatively just reboot daq-rix-andor-01.
Remote Power Cycling of Cameras
As of Nov. 17, 2023 rix now has a control panel to remotely power cycle andor cameras:

Workaround for RIX ANDOR-DIR hang
NOTE: We have seen cases where this does not work and we are forced to power cycle daq-rix-andor-01 to recover.
This is for when the camera is visible with "lsusb | grep Andor" (note uppercase "A") but the camera isn't communicating:
