2.5	Hot-Swappable Components
2.5.1	Hot-Swap Capabilities
	The subsystem comes with a number of hot-swappable components. A hot-swap component
	is one that can be exchanged while the subsystem is still online without affecting the opera-
	tional integrity of the subsystem. These components should only be removed from the subsys-
	tem when they are being replaced. At no other time should these components be removed
	from the subsystem.
2.5.2	Components
	The following components are all hot-swappable:
	• Power supply units (PSUs)
	•	Cooling fan modules
	•	Hard drives
	•	BBU module
2.5.3	Normalized Airflow
	Proper subsystem cooling is referred to as “normalized” airflow. Normalized airflow ensures

the sufficient cooling of the subsystem and is only attained when all components are properly installed. Therefore, a failed component should only be hot-swapped when a replacement is available. If a failed component is removed but not replaced, permanent damage to the sub- system can result.

Insert the new PSU module into the subsystem Once the previously removed cooling module has been installed, insert the new PSU module into the subsystem. Make sure the extraction lever is in its downright position so that the saddle notches on the lower edges of the handle can lock on to the edge metal brackets along the chassis inner walls.
