If the logic analysis system powers itself down
16900A, 16902A, and 16902B logic analysis systems
The power LEDs on the frame help to figure out why a frame has powered 
itself down. For safety purposes, when any of these LEDs are lit the frame 
will not power back up until the power cord has been disconnected and 
then reconnected.
The colors indicate:
• Green — front power supply failure.
• Yellow — side power supply failure.
• Red — fan failure or ‘overtemp’.
For any of the above conditions, go to
