10 IBM Certification Study Guide AIX HACMP
Your slot configuration must also allow for the disk I/O adapters you need to
support the cluster’s shared disk (volume group) configuration. If you intend
to use disk mirroring for shared volume groups, which is strongly
recommended, then you will need to use slots for additional disk I/O
adapters, providing I/O adapter redundancy across separate buses.
The following table tells you the number of additional adapters you can put
into the different RS/6000 models. Ethernet environments can sometimes
make use of the integrated ethernet port provided by some models. No such
feature is available for token-ring, FDDI or ATM; you must use an I/O slot to
provide token-ring adapter redundancy.

The switch adapter is onboard and does not need an extra slot.
