1.4. Hot-swappable Components
1.4.1 Hot-swap Capabilities
The FALCON subsystem comes with hot-swappable components 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.
1.4.2 Components
The following components are all hot-swappable:
RAID controller modules
PSU modules
Host I/O modules
Cooling modules
Hard drives
BBU modules
1.4.3 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 the
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 subsystem can result.
