• Four PCI/PCI-X card slots on two busses. These 64-bit slots can contain 33-MHz
and 66-MHz PCI cards, or 66-MHZ and 100-MHz PCI-X cards. Your base compute
system comes standard with an IO9 PCI card that is installed in the lowermost of
these slots.
Note: Because the IO9 card is a PCI card that runs at 66 MHz, the slot in the same
bus as the IO9 card (bus 1, slot 2) can only run in PCI mode and no faster than 66
MHz.
• Two DB-9 serial ports. One labeled
enables you to connect a system console to the L1 controller on the compute
module. The other, labeled
modem to the compute module.
• Type B USB (Universal Serial Bus) L1 port, which connects the compute module to
an L2 controller.
• Factory-installed serial daughtercard (in the base compute module), which includes
the following:
– Three DB-9 serial ports, which connect RS-232/RS-422 serial devices, such as
modems or printers, to the server system.
– Two PS/2 connectors, one to connect a PS/2 keyboard, and one to connect a
PS/2 mouse.
• IO9 card, which provides the following connectors and functions to your compute
module:
– Real-time interrupt input (RTI) port, and real-time interrupt output (RTO) port.
– 10/100/1000 BaseT Ethernet port.
– 68-pin VHDCI Ultra3 SCSI connector.
Table 3-1 compares an Origin 300 server system with an Origin 350 server system, and
highlights the expanded functionality of the compute module.
