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 hot-swappable:
•
Controller modules (in dual-active mode)
•
Host connection modules
•
PSUs
•
Cooling modules
•
BBUs
•
Hard drives
NOTE:
Instructions on how to replace these hot-swappable components are given
in Chapter 5.
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 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.
