Front Panel Key Codes

Inspect Cables

Remove the front panel assembly and visually inspect the ribbon cable that connects the

front panel to the motherboard. Also, inspect the interconnecting ribbon cable between A1

and A2. Make sure the cables are properly connected. Replace any bad cables.

Test Using a Controller

If a controller is available, write a simple command to the analyzer. If the analyzer

successfully executes the command, the problem is either the A2 front panel interface or

W17 (A2 to motherboard ribbon cable) is faulty.
