A SCSI Devices SCSI Guidelines When installing and operating SCSI devices, you must follow these guidelines: Ä ■ A narrow (50-pin) SCSI controller allows you to daisy-chain up to 7 additional SCSI devices. Counting the controller, that amounts to 8 total SCSI devices. ■ A wide (68-pin) SCSI controller allows you to daisy-chain up to 15 additional SCSI devices. Counting the controller, that amounts to 16 total SCSI devices.
SCSI Devices ■ 68-pin SCSI controllers require a 53 inch maximum length-twisted pair, LVD cable with built-in terminator, maximum of 5 drives with a minimum driving spacing of 5.25 inches. ■ Every SCSI chain or circuit must be terminated (closed) at both ends. Some system boards have both ends of the SCSI cable connected to, and terminated by, the system board. Termination can be accomplished in one of several ways: ■ ❏ Use a cable with a built-in terminator.
SCSI Devices Using SCSISelect with SCSI Devices The Ultra160 and faster SCSI host adapters includes the SCSISelect utility to configure the host adapter and to run the SCSI disk utilities.
