512512final.qxd 12/17/99 2:05 PM Page 5 Check the SCSI IDs The Adaptec SCSI Card 29160N and each device you connect to it must have a unique SCSI ID number ranging from 0 to 15. No two devices can have the same number. The Adaptec SCSI Card 29160N is preset to ID 7 and should not be changed. If you boot from a SCSI hard disk, make sure the hard disk SCSI ID is set to 0 or 1. Most SCSI hard disks come from the factory preset to ID 0. The IDs for internal devices are usually set with jumpers; external devices are usually set with a switch on the back of the device. Terminate the Ends To ensure reliable communication on the SCSI bus, the device at the end of each cable, or the end of the cable itself, must have a terminator installed (or enabled). Terminators must be removed, or termination must be disabled, on devices between the ends of each cable. 5
