Chapter 1: Introduction
1.4 Hot-swappable
Components
1.4.1 Hot-swap
Capabilities
The F16F 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 hot-swappable:
BBUs
Controller modules (in a dual-controller configuration)
Host connection modules
Drive loop extension modules
PSUs
Hard disk 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 removed when a replacement is available.
If a failed component is removed without a replacement, disruptions to
airflow will result causing the subsystem to quickly overheat.
