Segment C: 64-bit / 133 MHz PCI-X Capable Subsystem
The 64-bit/133 MHz PCI-X segment includes:
One 3.3 V keyed full-length, full height PCI expansion slots that can support PCI-X add in
cards up to 133 MHz (PCI-X Slot 1). This slot is backward compatible to 64-bit/100 MHz, 64-
bit/66 MHz, 64-bit/33 MHz, and universal keyed 32-bit/33 MHz PCI cards.
Dual Channel Gigabit Ethernet Controller (Intel 82546EB)
The PCI-X features include:
Bus speed up to 133 MHz
3.3 V signaling environment
Burst transfers up to a peak of 1000 Megabytes per second (MB/s)
8-, 16-, 32-, or 64- bit data transfers
Plug-and-Play ready
Parity enabled
NOTES
If you install a slower card into the PCI-X 64/133 connector, the bus speed for the
connector and for the onboard NICs will be lowered to the speed of the installed card.
Segment B: 64-bit / 100 MHz PCI-X Capable Subsystem
The 64-bit/100 MHz PCI-X segment includes the following embedded device and connectors:
Two 3.3 V keyed full-length, full height PCI expansion slots that can support PCI-X add in
cards running at 100 MHz (PCI-X Slots 2 and 3)
bit/66 MHz, 64-bit/33 MHz and universal keyed 32-bit/33 MHz PCI cards.
Integrated Adaptec AIC-7902 U320 Dual Channel SCSI Controller
The PCI-X features include:
Bus speed up to 100 MHz
3.3 V signaling environment
Burst transfers up to a peak of 800 Megabytes per second (MB/s)
8-, 16-, 32-, or 64-bit data transfers
Plug-and-Play ready
Parity enabled
NOTE
If you install a slower card into one of the PCI-X 64/100 connectors, the bus speed
for both connectors and for the onboard SCSI will be lowered to the speed of the
slowest adapter.
