Drive Removal and Replacement
1. Turn the instrument off and remove the AC power cord.
2. Before replacing the A5 disk drive it is highly recommended that the
factory calibration data be backed up to an external drive if at all possible.
If this data is not backed up prior to replacing the disk drive all instrument
adjustments and performance verification tests will need to be run after
the drive is replaced.
For information on how to backup this data see the “Calibration Data
Backup and Restore” section in Chapter 17, “Post-Repair Procedures.” of
this manual.
If this data cannot be backed up because the instrument will not fully
boot, go ahead and change the A5 Disk Drive and perform all adjustments
listed in Chapter 17, “Post-Repair Procedures.” for the A5 assembly.
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation. Refer to the
documentation that pertains to your instrument for information about static-safe workstations
and ordering static-safe accessories.
