Four 66-MHz PCI/PCI-X slots are shared in groups of two. Shared slots have many speed and
mode change restrictions during hot-plug add or remove operations. For more information on
PCI/PCI-X card configuration and restrictions, see “PCI/PCI-X/PCIe Configurations” (page 194).
Four of the server PCI/PCI-X slots are not shared. Two of the nonshared slots are 133 MHz
PCI/PCI-X, and two of the slots are 266-MHz PCI/PCI-X. Shared slots have many speed and mode
change restrictions during hot-plug add or remove operations.

PCI/PCI-X/PCIe IOBP
On the 10 slot PCI/PCI-X/PCIe IOBP there are a total of eight Public slots (four PCI-X mode 1 and
four PCIe), two Private Fast-core slots (PCI/PCI-X mode 1 64-bit/66-MHz), and one Private Slow-core
UCIO slot (PCI 32-bit/33-MHz). The eight Public slots are further divided into three speed/bandwidth
configurations:
• Two PDHP, which operate at 64-bit/66-MHz PCI-X
• Two PSHP, operating at 64-bit/133-MHz PCI-X
• Four PCIe 8-lane (x8) 2.5 Gbps, two of which are switched
The two 66 MHz PCI/PCI-X slots are shared. Shared slots have many speed and mode change
restrictions during hot-plug add or remove operations.
