•
One connector that connects the PCI riser to the IP45 motherboard
•
Two 64-bit universal PCI connectors that seat the PCI cards
•
One nonstandard PCI connector that connects the PCI riser to the I/O-8 board
assembly
•
One 50-pin AMP connector that connects the PCI riser to the I/O-8 board assembly
Note: Refer to the SGI Supportfolio Online home page at http://support.sgi.com for a
list of supported PCI option cards.
The SCSI backplane provides a connection between the internal SCSI interface on the
I/O-8 board and up to two disk drives. The SCSI backplane supports Ultra3 SCSI LVD
disks with a peak transfer rate of 160 MB/s. Refer to the SGI Supportfolio Online home
page at http://support.sgi.com for an updated list of supported drives.
The chassis accommodates up to two sled-mounted 3.5-in. by 1.0-in. Ultra3 SCSI LVD
drives. The backplane supports 10,000-RPM and 15,000-RPM drives.
The SGI Origin 300 base module uses a nonredundant modified WTX power supply with
an input of 110/220 Vac (auto-sensing) and a maximum output of 460 W (3.3/5/12 Vdc).
The DC power from the power supply is delivered via a cable harness, which has
multiple connectors for power delivery.
The Origin 300 base module is cooled by three fans in an N+1 redundant configuration.
The power supply also uses an N+1 redundant cooling configuration; it is cooled by two
fans. The direction of the airflow is front to back through the enclosure.
