The leftmost PCI-X slot (bus 1, slot 1) seats an IO9 card that has the following connectors:
• SCSI 68-pin VHDCI connector. This external SCSI port connects to SCSI devices.
• Ethernet RJ45 connector. This autonegotiating 10/100/1000BaseT Ethernet port
connects the system to an Ethernet network.
• RTO and RTI stereo jack connectors. RTO (output) enables a Cx-brick to interrupt
an external device. RTI (input) enables an external device to interrupt a Cx-brick.
The IO9 card also connects to a daughtercard (standard component) that has the
following connectors:
• Two DB-9 RS-232 serial port connectors. These ports can be used as COM ports to
connect to modems or other serial devices.
Note: An optional serial port daughtercard can be attached to your IO9 card by an SGI
system support engineer (SSE). This card adds two additional serial ports to the IX-brick.
