Hot-swappable Components

2.5.1

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.

2.5.3

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.
