must remain empty. All GX+ cards are hot-pluggable. The RIO-2 ports are used for I/O expansion to external I/O drawers. The supported I/O drawers are the 7311 Model D10, 7311 Model D11, and 7311 Model D20.

The Remote I/O expansion card must be installed starting with the first p5-570 building block.

2.4.2 SP bus

In addition to the processor drawer interconnect cable (described in 2.2.1, “Processor drawer interconnect cables” on page 24), the interconnection of multiple p5-570 building blocks requires the proper SP Flex cable to ensure the vital data communications between the building blocks. (See Figure 2-9 on page 28.) The SP Flex cable contains the system interconnect signals such as JTAG, I2C, clocks, and others.

2.5 Internal I/O subsystem

The internal I/O subsystem resides on the system planar, and the SP is packaged on a separate service processor card. Each card is a separate FRU. An internal RIO-2 bus is imbedded in the system planar. The system planar contains both the Enterprise RIO-2 hub and the PCI-X Host bridge chip to connect to the integrated I/O that is packaged on the system planar. Two RIO-2 ports of the Enterprise hub chip are used for the integrated I/O and the remaining two ports are routed to external connectors.

2.5.1 PCI-X slots and adapters

PCI-X, where the X stands for extended, is an enhanced PCI bus that delivers a bandwidth of up to 1 GBps, running a 64-bit bus at 133 MHz. PCI-X is backward-compatible, so the p5-570 can support existing 3.3 V PCI adapters.

The system planar provides six PCI-X slots and several integrated PCI devices that interface the three PCI-X to PCI-X bridges to the primary PCI-X buses on the PCI-X Host bridge chip.

PCI-X slot 6 can accept a short PCI-X or PCI card, and its space is shared with the Remote I/O expansion card, therefore if the Remote I/O expansion card is installed, this slot must remain empty. The remaining PCI-X slots are full-length cards. The dual 1 Gb Ethernet adapter is integrated on the system planar.
