Using a Quantum 984 HSBY System

Advanced Options

Advanced	When pressing the Advanced Options button in the Hot Standby dialog, you get the
Options button	opportunity to allow different firmware versions on the Primary and Standby
	controller while running in full Hot Standby mode.
	Concept shown

This lets you upgrade the controllers step by step to a new firmware version without having to shutdown the system. Since this is only necessary in rare situations, it is recommended that you disable this mode by configuration and to enable it by the reference data editor or Zoom screen when needed. By default, the controllers must have the same versions of firmware. This means the Standby controller would not go online while having a newer or older firmware version than the one on the Primary controller.
