Stack construction method 2: Manual configuration
Description
With this method, user should configure every unit individually and enable stacking on each unit. Once
the units are connected together, they automatically form a stack. With this method, the unit with the
highest priority becomes the active controller, and ID assignment is determined by the sequence in
which user physically connects the units. The example used below is 12 units to form a linear stack.
Steps
Manual stack formation:
• Configure the highest priority on an intended active controller.
• Configure second highest priority on an intended standby controller.
