Some components in the modular system are removable and serviceable.
Serviceable components are two types:
CRUs can be removed and replaced by any qualified technician.
FRUs must be removed and installed only by authorized Oracle service personnel.
Components have three service classifications:
Hot-pluggable – Using the proper software commands, you can install or remove hot-pluggable components while the modular system is running.
Hot-swappable – You can install or remove hot-swappable components while the modular system is running, without using any software commands.
Cold-swappable – You must remove power from the modular system to service the components.
