Migrate D20MX application definitions to SGConfig

Prerequisites
Procedure
D20MX HARDWARE USER'S MANUAL
A previously committed version of the firmware may be recovered from secondary
storage.
This feature is intended to be used when the primary version of the firmware has become
corrupt. Reverting the firmware copies the firmware from secondary storage into the
primary storage.
If, after downloading a new version of the firmware, an issue is identified in the new
firmware, the previous version may be recovered. This is only possible if the new firmware
has not been committed; see Section: Committing new firmware.
To commit new firmware:
1. Login as a user that has Maintenance or Read/Write access privileges.
2. Enter the D20M Shell.
3. Enter the revert command
Result: A prompt appears to confirm copying the firmware from Secondary to Primary.
4. Enter yes to confirm the copy operation. If anything else is entered, the command is
canceled.
Result: The firmware copy operation begins. Both 'vxworks' and 'appl.out' are copied.
This operation takes approximately 3 minutes.
DO NOT shut off the power to the D20MX while the copy operation is in progress. If power
to the D20MX is disrupted, during the copy operation, the firmware will likely be corrupted.
5. Once the copy operation has completed, enter the boot command to restart the
D20MX with the reverted firmware.
