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.
The system might update system firmware when it boots. Do not abort this process. The
procedure requires you to interrupt the boot process, which you can typically do at any time after
prompted to do so. However, if the system updates the system firmware when it boots, you must
wait until after the update is complete before interrupting the boot process.
Steps
1. If you are not already grounded, properly ground yourself.
2. If you have not already done so, replace the cover on the controller module.
3. Align the end of the controller module with the opening in the chassis, and then gently push the controller
module halfway into the system.
Do not completely insert the controller module in the chassis until instructed to do so.
4. Cable the management and console ports only, so that you can access the system to perform the tasks in
the following sections.
You will connect the rest of the cables to the controller module later in this procedure.
5. Complete the reinstallation of the controller module:
