The customer requires a non-disruptive software upgrade on a Nexus 5548UP. The ISSU compatibility output confirms that the upgrade is completely non-disruptive however a power sequence upgrade is required on module 1. According to Cisco documentation, 'After a successful power sequence upgrade, you must switch off the power to the system and then power it up' and that's it! The customer does not wish to restart the device. What will happen if the switch is not reloaded? Will the device continue to run on the existing power sequencer image and only the new image when reloaded?
