Disconnected ethernet and plugged into test computer and it connected and ran and took images and was sensitive to light. When it started taking images teh fan turned on and continued to run after disconnecting from computer and reconnecting to SONG system. Camera cooled down a little over the next 20min, but was still quite warm. Otherwise it now seems to be running (with the fan on) fine.
