Ultra320 SCSI Connectors: SCSI1 (Optional)

SCSI (Small Computer System Interface) is a parallel interface standard for
attaching peripheral devices to computers. Ultra320 SCSI is the seventh generation
of SCSI I/O technology, and has a maximum data rate speed of 320 MB/sec. SCSI's
commitment to backward compatibility and legacy support are the primary reasons for
its durability as an I/O interface, making SCSI the industry standard for disk drive
connection in virtually all high-performance servers.

SCSI LED Connector: J14 (Optional)

This connector is used to connect to a LED for showing the activity of SCSI
devices attached to the SCSI connectors.
