PRIORITY: TEST_TYPE: APPROVED_QE: INPUT: 1. Use DLM which has different version of some peripheral modules (IIT, IOT, Finisher, etc) and NC software set is lesser than machine software set number. 2. Ensure USB ports are enabled in the device. FILES: TESTCASE_HEADLINE: POSU - When NC software set number is lesser than Machine software set number TESTCASE_VERSION: AUTOMATABLE_NOTAUTOMATABLE: FEATURE: APPROVE_SE: SPEC_VERSION: 1.0115.

Once the NC has synchronized after upgrade the CCS compares the NC Software Set Number with the Machine Software Set Number and if there are any mismatches POSU will be performed using NC software set.\ Note: Only the modules which has different software versions will be upgraded via POSU.

If these NC versions are different the machine commences a software downgrade using the NC Software Set. Only platforms/modules which contain no valid version or a different version to that contained in the NC Software Set are modified.  PROCEDURE: 1. Copy the DLM file into Altboot directory of USB. 2. Insert the USB in enabled port of the device and Reboot the device.
