Hot-swappable Components
2.7.1
Hot-swap Capabilities
The RAID subsystem comes with a number of hot-swappable components. A hot-swap compo-
nent is one that can be exchanged while the subsystem is still online without affecting the 
operational integrity of the subsystem. These components should only be removed from the 
subsystem when they are being replaced. At no other time should these components be 
removed from the subsystem.
2.7.2
Components
The following components are hot-swappable:
•
Power supply units (PSUs)
•
Cooling modules
•
BBU
•
Hard drives 
2.7.3
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.
