SCSI Termination SCSI Termination The DAC960PG and DAC960PJ are equipped with automatic SCSI termination circuitry. If the controller is at the end of a SCSI bus, it automatically enables on-board termination. If all the SCSI devices on a channel are connected either to an internal connector of a channel, or to an external connector of a channel, the end of the SCSI bus farthest from the controller must have a terminator installed. In this case, the controller automatically enables on-boar

Preinstallation Planning Figure 2-1. DAC960 Controller Termination Examples ☛ Note For this discussion, assume that the illustrated internal and external connectors are both on the same channel. It is better to terminate the ends of the SCSI bus itself than it is to terminate the end devices on the bus. This allows hot swap devices to be added or removed from the SCSI bus without affecting termination. Manual No. 775012 2-3

Preinstallation Planning SCSI Drive Preparation Prepare the drives for installation as follows: Remove any terminators attached to the drive or set any drive termination jumpers to the disabled position. Set the SCSI addresses on the drives. ☛ Note Each drive on a channel must have a unique ID chosen from 0 through 6 or 8 through 15. ID 7 cannot be used as a drive ID because it is reserved for the controller. Enable term power on the drives. Refer to the drive manual for specific infor
