Hot-Pluggable FRUs
A FRU is defined as hot-pluggable if it can be removed from the chassis while the system remains

The following FRUs are hot-pluggable:
• Removing and Replacing a Disk Drive
• Removing and Replacing a Core I/O Board
• Removing and Replacing a Cell Board
• Removing and Replacing a PCI/PCI-X Card
Hot-Swappable FRUs
A FRU is hot-swappable if it can be removed from the chassis while the server remains operational
and requires no software intervention prior to removing the FRU.
The following Frus are hot-swappable:
• Removing and Replacing a Front Smart Fan Assembly
• Removing and Replacing a Rear Smart Fan Assembly

• Removing and Replacing a Bulk Power Supply
Other FRUs
To remove and replace the FRUs that are neither hot-pluggable nor hot-swappagle, you must
shut down HP-UX in the nPartition where the FRU resides, and power to the FRU must be turned
off before removing it. For complete instructions, see “Shutting Down nPartitions and Powering
Off Hardware Components ” (page 96) and Appendix D.
