Component Fillers
Depending on configuration, each server is shipped with replacement fillers for hard drives and
processor modules. A filler is an empty metal or plastic component that does not contain any
functioning system hardware or cable connectors.
The fillers are installed at the factory and must remain in the server until you replace them with
a functional component to ensure proper airflow through the sytem. If you remove a filler and
continue to operate your system with an empty slot, the server might overheat due to improper
airflow. For instructions on removing or installing a filler for a server component, refer to the
topic in this document about servicing that component.
