These procedures are intended for use by trained and experienced HP service personnel only.
Hot-Pluggable FRUs

operational, but requires software intervention before removing the FRU.
The following FRUs are hot-pluggable:

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 before removing the FRU.
