Hot Pluggable Components Overview
The Sun Fire X4500 server hot-plug technology allows a component to be added,
upgraded, or replaced while the system is running without affecting hardware
integrity.
Hot-plugging provides the ability to physically add, remove, or replace a hard disk
drive while the system is running, and other hard disks in the system provide
continuous service. Before a hot-pluggable component is removed from the Sun Fire
X4500 server, the component must be taken offline from the operating system first,
but does not require that the server be powered off.
On the Sun Fire X4500 server, you can hot-plug the following components:
