Bus, high-speed link (HSL or RIO) isolation information
Symbolic FRUs, failing items (FIs), and bus isolation procedures
use the terms "partition" and "logical partition" to indicate any
single partition in a system that has multiple partitions. If the system you
are working on does not have multiple partitions, then the terms refer to
the primary partition.
Please read all safety notices below before servicing the system and while
performing a procedure.
Note:
Unless instructed otherwise, always power off the system before removing,
exchanging, or installing a field-replaceable unit (FRU).
