This connector supplies power to the hard disk activity LED. The read or
write activities of any device connected to the SCSI connectors or the
SATA connectors cause this LED to light up.

This motherboard comes with the Adaptec
® AIC-7901X PCI-X SCSI
controller that supports one 68-Pin Ultra320 SCSI connector. The SCSI
channel can support a maximum of 15 SCSI devices as specified by
Ultra320 standards.

This motherboard has a 68-Pin Ultra320 SCSI connector.
The onboard SCSI chipset incorporates an advanced multimode I/O cell
that supports both single-ended (SE), Ultra2, Ultra160, and Ultra320
devices. With Ultra320 devices, the SCSI bus platform performs at full
Ultra320 speeds (up to 320 MB/s) and extended cabling 12m (or 25m
in a point-to-point configuration). When an SE device is attached, the
bus defaults to an SE speed and 1.5m cable length.
Connect SCSI devices as specified. A SCSI channel should have only one
type of SCSI standard (e.g. Ultra320, Ultra160, Ultra2, Ultra-Wide).
Mixing SCSI devices on a single channel decreases performance of the
slower device.
