Restore product data To ensure that customer-specific configuration information and data are preserved, back up the product data to a portable USB storage device prior to removing these assemblies. Restore the data after replacing the assembly. NOTE: You can also restore product data using the Embedded Web Server (EWS). See the product user guide for information. 1. From the Home screen on the product control panel, touch the Device Maintenance button. 2. Open the following menus: ● Backup/Restore ● Restore Data 3. Insert the portable USB storage device. 4. Select the backup file, and then touch Restore . 5. Touch Restore .
Save and repair process The save and repair process occurs automatically whenever the formatter PCA, interconnect PCA, or encrypted hard disk drive (HDD) are replaced. This process is transparent to the user. CAUTION: Replacing the formatter PCA and interconnect PCA at the same time or swapping these assemblies between products can render the product unusable. ● Formatter PCA: When a replacement formatter PCA is installed and the product is turned on, NVRAM values from the interconnect PCA are transferred automatically to the replacement formatter PCA. This process allows the product to return to normal operation with all of the necessary product history. ● Interconnect PCA:
When a replacement interconnect PCA is installed, NVRAM values from the formatter PCA are transferred automatically to the replacement interconnect PCA. This process allows the product to return to normal operation with all of the necessary product history. ● Hard disk drive (HDD): When a replacement hard disk drive is installed and product is turned on, the replacement hard disk drive is locked to the formatter PCA of the product. The encryption key is placed in the NVRAM of the formatter PCA and copied to the NVRAM of the interconnect PCA.
This allows the backed up NVRAM values from the interconnect PCA to be restored to a replacement formatter PCA when either the formatter PCA or interconnect PCA are replaced. This process also allows the hard disk drive to function when it is transferred from a defective formatter PCA to a replacement formatter PCA. The hard disk drive cannot be used in another product or accessed from outside the product. Post-service test Perform the following test to verify that the repair or replacement was successful. 16 Chapter 2 Removal and replacement ENWW
