1-10 System OverviewI/O Expansion SlotsThe server's expansion capabilities meet the needs of file and application servers forhigh performance I/O by providing a combination of PCI and ISA expansion slots.The system board has two full-length 66 MHz PCI connector slots (see A in figurebelow) that can accommodate either a 32 or 64 bit PCI card and one full-length 33 MHzPCI connector slot (see B in figure below) that can accommodate either a 32 or 64 bitPCI card, as shown in the following figure. The top two PCI connector slots (PCI 1 andPCI 2) support bus speeds up to 66 MHz. The third connector slot (PCI 3) only supportsa bus speed of up to 33 MHz.Note: The bus speed for the two 66 MHz PCI connector slots(PCI 1 or PCI 2) is decreased to 33 MHz, if a PCI card is installedinto connector slot PCI 3 or if a 33 MHz PCI card is installed into anyone of the two 66 MHz PCI connector slots.PCI features:! Bus speed up to 66 MHz (PCI 1 and PCI 2)! Bus speed up to 33 Mhz (PCI 3)! 32-bit memory addressing! 5 V/3.3 V signaling environment! Burst transfers up to a peak of 264 MB/s (64 bit, 33 MHz PCI) and 528 MB/s(64 bit, 66 MHz PCI)! 8-, 16-, 32-, or 64-bit data transfers! Plug and Play ready! Parity enabled.
