NOTE: The differences between the PCI X backplane and the PCIe backplane are as follows:
• Twelve ropes are bundled in two rope pairs to 6 LBAs to support 6 slots for PCI and PCI-X
cards instead of 14. These ropes are capable of 133MHz.
• Sixteen ropes are bundled into dual fat ropes to 8 LBAs to support 8 additional slots for
PCIe cards. These ropes are capable of 266MHz.

1 Each slot will auto select the proper speed for the card installed up to the maximum speed for the slot. Placing high
speed cards into slow speed slots will cause the card to be driven at the slow speed.
2 Slot is driven by a single rope and has a maximum speed of 66 MHz.
Core I/O Card
Up to two core I/O cards can be plugged into the server. Two core I/O cards enable two I/O
partitions to exist in the server. The server can have up to two partitions. When a Server Expansion
Unit with two core I/O cards is attached to the server, two additional partitions can be configured.
A core I/O card can be replaced with standby power 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.
