Introduction
Overview

The PCI-X backplane is physically one board but behaves as two independent partitions. SBA 0 and its
associated LBAs and eight PCI-X slots form one I/O partition. SBA 1 and its associated LBAs and eight PCI-X
slots form the other I/O partition. One I/O partition can be powered down separate from the other I/O
partition.
Core I/O Card
Up to two core I/O cards may be plugged into the HP 9000 rp8420 server. Two core I/O cards allows for two
I/O partitions to exist in the HP 9000 rp8420 server. A single server may support up to two partitions and
with a Server Expansion Unit (SEU) attached to the server, will support up to four partitions.
The core I/O card can be replaced with standby power (5V) applied. The system power to the core I/O is
handled in the hardware the same way a hot-plug PCI/PCI-X card is handled. Standby power to core I/O is
handled by power manager devices to limit inrush current during insertion.

a. If the slot is used as a PCI slot, then either the 33MHz or 66MHz PCI frequency is supported. If
the slot is used as a PCI-X slot, then either the 66MHz or 133MHz PCI-X frequency is supported.
