Additional Tasks

Calibration Data Backup and Restore
In order for the instrument being repaired to not need all of the instrument
adjustments and performance verification tests to be run after the A5 Disk
Drive is replaced the calibration data will need to be backed up onto an
external drive prior to removing the existing disk drive.
While the backing up and restoring of the calibration data to the new disk
drive will return the instrument performance to the state that it was prior
to a repair this does not guarantee that all instrument performance
parameters meet their specified values. A full instrument calibration
would be required to verify this.
Data Backup
There are two different backup procedures that might need to be followed.
Which backup procedure to be run will depend on whether the software will
run or not.
If the Instrument Software Application Will Run
1. Connect a USB keyboard and mouse to two of the instrument rear panel
2. Connect a USB FLASH drive to one of the front panel USB port.
3. Press System, Alignments, Backup or Restore Align Data.
4. After the XSA application closes the Alignment Data Wizard window as
476
USB ports
shown in Figure 16-1 will appear.
