DK424 Release 4.0 Upgrade Procedure

1.Using DKAdmin or DKBackup Release 4.0, download the customer data from the currently installed processor. Save this “Customer” data as a backup in case you must re- install the current processor and/or processor ROM/Flash memory release level.

Note You must use DKAdmin or DKBackup Release 4.0 for this procedure. Prior releases of these programs do not provide DK Release 4.0 Upload/Download/Upgrade capabilities.

2. Using DKAdmin or DKBackup, create a new customer for the upgrade.

Important! When creating the new customer, select the currently installed processor type and release level—not the R4.0 Release level.

3.Using DKAdmin or DKBackup, select the customer created in Step 2 (not Step 1).

4.Start the upgrade procedure, using the Upgrade (F5) function from the “Backup/Restore Data” menu.

5.Choose Yes when prompted to Backup From DK First.

6.After the current data is downloaded, follow the DKAdmin/DKBackup screen instructions to change the processor and/or ROMs/flash memory and reinitialize. The procedure for changing ROMs and flash memory is provided in figures on the following pages of this appendix.

Important! When changing the processor and ROM/flash memory for the “Upgrade to” processsor, you can add one RSIU to complete the upgrade at 9600 bps. However:

Do not add a new station or Tie/DID line PCBs.

Do not change the order in which the PCBs are installed in the slots.

Be sure to reinitialize the “Upgrade to” processor twice and set the DK TTY port with Programs 76 and 03.

7.Continue with the upgrade procedure as prompted by the DKAdmin or DKBackup screens until the process is complete.

Note An upgrade example, “DK424 Release 4.0 Upgrade Programming Example” on Page 154, describes what changes take place in the customer data during the DKAdmin/DKBackup upgrade procedure to make the upgrade transparent to the end user.
