* 133 MHz operation with only one adapter installed on this PCI bus at system power on.
v You can install both PCI and PCI-X adapters on the same bus. However, if you
install a PCI adapter and a PCI-X adapter on the same bus, the PCI-X features
of the PCI-X adapter will be disabled, and the adapter will function as a PCI
adapter.
v You can install PCI or PCI-X adapters of speeds faster than what is labeled for a
particular PCI-X bus. For example, if you install two 133 MHz adapters into slots
that are labeled as 100 MHz slots, the adapters will operate at 100 MHz.
v If you install a 33 MHz and a 66 MHz adapter on the same bus, the bus speed
will match that of the slowest adapter.
v If a single 133 MHz adapter is installed on PCI-X bus B (slots 3 and 4) and the
other slot on PCI-X bus B is empty, the adapter will operate at 133 MHz.
v The server scans PCI-X slots in the following order: the xSeries 455 integrated
devices are scanned first; then, PCI-X slots 1, 2, 3, 4, 5, and 6. If an RXE-100
enclosure is attached to an xSeries 455 server, the scan order is as follows: the
xSeries 455 integrated devices are scanned first; then, PCI-X slots 1, 2, 3, 4, 5,
and 6; then, the RXE-100 slots 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.
v Your server supports 3.3 V and universal adapters; it does not support 5.0 V
adapters.
