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.

The following components are all hot-swappable:

•

Power supply units (PSUs)

•

Cooling fan modules

•

Hard drives

•

BBU module

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.
