Hot-plug Hardware

Hot-plug: hot-plug boards and modules have special connectors which supply electrical power to the board or module before the data pins make contact. Boards and devices which do not have hot-plug connectors cannot be inserted or removed while the system is running.

I/O boards and CPU/memory boards used in Enterprise x000 and x500 systems are hot-plug devices. Some devices, such as the clock board and peripheral power supply (PPS), are not hot-plug modules and cannot be removed while the system is running.
