Hot-Pluggable Frus - IBM pSeries 690 Service Manual

Hot-Pluggable FRUs

Notes:
1. The Linux operating system does not support some hot-pluggable procedures.
2. Linux does not support hot-plugging any hot-pluggable PCI adapters or devices. A system with Linux
installed on one or more partitions must be shutdown and powered off before replacing any PCI
adapter or device assigned to a Linux partition. Follow the non-hot-pluggable adapter or device
procedures when replacing a PCI adapter or device in any partition with Linux installed.
3. You do not have to power off the system to remove a hot-pluggable FRU from the processor
subsystem or from I/O subsystems.
FRUs can be considered as not concurrently replaceable, concurrently replaceable with hot plug, or
concurrently replaceable. The following table indicates which FRUs are hot-pluggable or
non-hot-pluggable. Each FRU shown is identified as available for concurrent maintenance if applicable.
