Installing the controller
After you install the components from the old controller module into the new controller module, you must
install the new controller module into the system chassis and boot the operating system.
About this task
For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller
module is especially important because it attempts to reboot as soon as you completely seat it in the
chassis.
