Supported I/O Adapters In P5-595 And P5-590 Systems - IBM p5 590 System Handbook

Powering down all the system enclosures on critical power faults.
Verifying power configuration.
Reporting power and environmental faults, as well as faults in the RAS
infrastructure network itself, on operator panels and through the service
processor.
Assigning and writing location information into various VPD elements in the
system.
Note: It is the cabling between the RIO-2 drawer and the BPA that defines the
numbering of the I/O drawer not the physical location of the drawer.
The power and RAS infrastructure monitors power, fans, and thermal conditions
in the system for problem conditions. These conditions are reported either
through an interrupt mechanism (for critical faults requiring immediate operating
system action) or through messages passed from the RAS infrastructure to the
service processor to Run-Time Abstraction Service (RTAS).

2.7.8 Supported I/O adapters in p5-595 and p5-590 systems

The following are configuration rules for the I/O drawer.
I/O Drawer (5791/5794) adapters placement (p5-590 and p5-595 only)
The FC 5791 drawer provides 20 blind-swap hot-plug PCI-X slots and 4
integrated DASD backplanes that support up to 16 hot-swappable disk bays. The
FC 5794 drawer is the same as FC 5791 but supports only two integrated DASD
backplanes that support up to eight hot-swappable disk bays. The 20 PCI-X slots
are divided into six PCI Host Bridges (PHB) as follows:
PHB1 = slots 1, 2, 3, 4
PHB2 = slots 5,6,7; Z1 onboard
PHB3 = slots 8,9,10, Z2 onboard
PHB4 = slots 11, 12, 13, 14
PHB5 = slots 15, 16, 17, Z1 onboard
PHB6 = slots 18, 19, 20, Z2 onboard
