• Two PCI slots (P5-P6) support full-length 32- or 64-bit boards at clock
rates of 33 MHz. These slots only support +5 VDC power and Universal
boards. These slots have keys in the upper half of the board slot to prevent
3.3 volt boards from being inserted into the slots.
CAUTION Some accessory board outputs may exceed U.S. National
Electrical code (NFPA 70) Class 2 or limited power source
limits and must use appropriate interconnect cabling in
accordance with the National Electrical Code.
• I/O connections – The system board provides connections to support the
video monitor, mouse, keyboard, one serial port, one management port,
one parallel port, and an embedded NIC port.
