Server component classification
The server components are classified into three major categories:
• Hot-swappable
• Hot-pluggable
• Cold-swappable
A brief explanation of each category and the classifications for the server components follow.
Hot-swappable components
A component is defined as hot-swappable if you can remove it from the server while the server
remains operational, and requires no software intervention prior to removing the component.
NOTE: Hot-swappable components are signified with red touch points.
The following are hot-swappable components:
• Power supplies (only if two are installed)
• Server fan
Hot-pluggable components
A component is defined as hot-pluggable if you can remove it from the server while the server
remains operational, but software intervention is required prior to removing the component.
NOTE: Hot-pluggable components are signified with red touch points.
The only hot-pluggable components are the SAS disk drives:
Cold-swappable components
To remove and replace cold-swappable components (components that are neither hot-swappable
nor hot-pluggable), shut down the operating system and power off the server. For complete
instructions on shutting down the operating system and powering off the server, see Chapter 4
(page 61).
