I/O Expansion Slots
The server's expansion capabilities meet the needs of file and application servers for
high performance I/O by providing a combination of PCI and ISA expansion slots.
high performance I/O by providing a combination of PCI and ISA expansion slots.
The system board has two 66 MHz PCI connector slots (Figure 1-6, A) that can
accommodate either a 32 or 64 bit PCI card and one 33 MHz PCI connector slot (Figure
1-6, B) that can accommodate either a 32 or 64 bit PCI card. The top two PCI connector
slots (PCI 1 and PCI 2) support bus speeds up to 66 MHz. The third connector slot
(PCI 3) supports a bus speed of up to 33 MHz.

(PCI 3) supports a 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 installed into
connector slot PCI 3 or if a 33 MHz PCI card is installed into any one
of the two 66 MHz PCI connector slots.
