The default| | A0 | OPEN x | value is six. | +---------+-----------+-------------------------------------------+ SS Self-Seek Jumper -------------------- The self seek test continuously exercises the actuator of the drive. To enable the self-seek test, install a jumper across the SS pins. Alternatively, the host can initiate a self-seek test by issuing a SEND DIAGNOSTIC command, with the self-seek bit set to one. When power is applied to the drive with the self-seek test enabled, the drive initiates a self-seek test. The SCSI-bus device identification (SCSI ID) currently selected determines the self-seek test performed. - If the SCSI ID is set to 6 (factory default), the drive will perform random seek patterns, verifying target ID's after every seek. The pattern will repeat as long as power is applied to the drive or until an error has occurred. - If the SCSI ID is set to any value other than 6, the drive will perform a bufferfly seek pattern, beginning with a single track seek at the middle cylinders and extending out to a full stroke seek. The pattern will repeat as long as power is applied to the drive. NOTE The self-seek test continously exercises the drive actuator until the jumper is removed from the SS jumper pins. ProDrive 40/80/105S drives are shipped from the factory with jumper SS not installed (self test disabled). EP Enable Parity Jumper ------------------------ The EP jumper option controls the checking of parity across the SCSI bus. When this jumper is installed, parity generation and parity checking of data across the SCSI bus is enabled. With this jumper removed, parity checking is not performed, although parity is still generated. ProDrive 40/80/105S drives are shipped from the factory with jumper EP installed (parity enabled). WS Wait/Spin Jumper -------------------- The WS jumper controls the Wait/Spin option. When a jumper is installed on the WS pins, the ProDrive 40/80/105S motor will not spin on power-up until the host sends the START/STOP UNIT command across the SCSI bus. This permits power sequencing so that the system power supply is not overloaded by multiple devices demanding peak start current at the same time. Once the drive receives the Start/STOP UNIT command, it will be ready within 15 seconds. When the WS jumper is not installed, the motor will automatically start spinning upon power up and be ready within 15 seconds. ProDrive 40/80/105S disk drives are shipped from the factory with jumper WS not installed (Wait/Spin option disabled). A2/A1/A0 SCSI-Bus Device Identification ---------------------------------------- The SCSI bus can support up to eight devices, including the host system. The identification number of each device determines its priority level. Prior to installing the ProDrive 40/80/105S hard disk drive, you must choose its SCSI-device identification number. Jumpers installed across three pair of jumper pins - A2, A1 and A0 - in various combinations permit the assignment of the drive's identification number. These three pairs of jumper together comprise a 3-bit binary number, in which A2 is the most-significant bit and A0 is the least significant bit. With a jumper installed, a pair of pins represents a 1; with no jumper installed a 0. Thus, with jumpers installed across all of the pins, the device identification is 7; with no jumpers installed, the device identification is 0. Quantum ships the ProDrive 120/170/210S hard disk drive from the factory with the A2 and A1 jumpers installed - that is, the drive's default SCSI-device identification is 6. If the jumpers are changed, the new device identification takes effect at the next power on. +----------+-----------------------+ | SCSI ID | Jumpers | | | A2 | A1 | A0 | +----------+-------+-------+-------+ | 0 | OPEN | OPEN | OPEN | +----------+-------+-------+-------+ | 1 | OPEN | OPEN | CLOSED| +----------+-------+-------+-------+ | 2 | OPEN | CLOSED| OPEN | +----------+-------+-------+-------+ | 3 | OPEN | CLOSED| CLOSED| +----------+-------+-------+-------+ | 4 | CLOSED| OPEN | OPEN | +----------+-------+-------+-------+ | 5 | CLOSED| OPEN | CLOSED| +----------+-------+-------+-------+ |x 6 | CLOSED| CLOSED| OPEN | +----------+-------+-------+-------+ | 7 | CLOSED| CLOSED| CLOSED| +----------+-------+-------+-------+ The SCSI bus supports up to eigth devices, including the host system.
