Page 11: Connection Considerations
Connection considerations If using a combination of Wide 16-bit devices and Narrow 8-bit devices on the same connector, Wide devices must be connected first (closest to Exhibit 3.1-2 Several types of internal and external cable connectors. Termination The SCSI bus is a chain of SCSI devices. The devices at both ends of any SCSI chain must be terminated for the SCSI bus to function correctly. - Page 12 This can be done in several ways. Many Single-Ended Ultra SCSI and earlier 9 ATTO Technology ExpressPCI Ultra/WIDE SCSI Host Adapters Installation and Operation Manual devices provide a jumper setting for applying termination: place a jumper over the pins designated for termination on the last device on the internal cable.
- Page 13 host adapters supply Termination power: termination power to the bus at all times and many SCSI devices are also able to supply termination power. SCSI signal quality, particularly with long or marginal quality cables, may be improved if the device supplies the termination power. Contact your device manufacturer for more information on your device’s ability to supply termination power.
