Practical Installation Case

During modernization of a power plant engineering workstation, an AIP434 Hard Disk Module was installed to replace an aging storage device.

Although the hardware installation was completed successfully, the workstation failed to access historical databases because the latest backup had not been restored.

After restoring the engineering database and process history:

• The workstation booted successfully.
• Historical data became fully accessible.
• Engineering software functioned normally.
• The maintenance team resumed plant support operations without data loss.

Frequently Asked Questions
