Initialize the AU processor with factory settings. Check the Cau ID number of the AU processor with Xtools Discover, confirm that the On/Off switch is set correctly and check the dial tones at the subscribers. 3-Turn off the power switch of the AU processor and start it in Service mode. Scan with Xtools / Explore and when Xtools finds it, double-click to link.   4- Click Remove Firmware and delete the old version of Xymphony. 5- Click Firmware Upload and upload the version of Xymphony the current CAU is using.  6- As described in item 4, select Remove Firmware again, delete the Xymphony version that the current CAU does not use, and upload the Xymphony version that the current CAU uses with Firmware upload as described in item 5. 7- Click on File system Cleanup and press the ok button   8- Restart the AU processor with factory settings, scan with Xtools / Discover and double click to connect when Xtools finds it. 9- Click WebServer and define username and password.   10-Click System / Time and set the date and time of the AU processor.
