6 ASUS PCI-SC875 User’s Manual

The following illustrations show the 50pin internal connector used with the ASUS

PCI-SC875. 68-pin Wide-SCSI connectors may also be used with Wide-SCSI de-

vices.

To connect internal SCSI devices, follow these steps:

1. Plug the SCSI connector at one end of the SCSI ribbon cable into one of the host

adapter’s internal SCSI connectors. Line up the colored stripe on the ribbon

cable with the number 1 printed below the connector on the host adapter. This is

called maintaining pin-1 orientation. Maintain pin-1 orientation throughout the

SCSI bus, or the devices will not work properly.

2. Plug the last connector on the ribbon cable into the SCSI connector on the inter-

nal SCSI device.

3. To connect a second internal SCSI device, plug the middle connector of the

SCSI ribbon cable into the SCSI connector on the second internal SCSI device.

4. To connect three or more internal SCSI devices to a SCSI bus, plug the remain-

ing middle SCSI connectors into the other internal devices.
