The most common settings are used to define the drive SCSI ID and bus termination. Quantum SCSI drives have additional jumper settings used for optional features found on the drive. Listed below are the various jumper options that may be found on Quantum SCSI drives and the corresponding feature that they enable. DS - Delay Spin At power on or reset the drive motor starts to spin automatically and the drive prepares itself to perform read or write operations. With the Spin Delay feature enabled, at power on or reset the host [SCSI adapter] must send a START/STOP UNIT command to activate the drive motor for read or write operations. Spin Delay allows the drive to perform power sequencing to prevent an overload of the system power supply due to simultaneous, peak start-up current demands from multiple devices. EP - Enable Parity When enabled the drive generates parity information and performs parity checking of data across the SCSI bus. When disabled, parity information is still generated but not checked. J13 - Termination Power When enabled this jumper supplies +5vdc termination power from the drive to the SCSI bus. With this jumper removed the SCSI bus must supply termination power. This jumper was used in place of the Term Power jumper on earlier model drives that supported Term Power as an option. At the factory, Quantum configures the disk drive with the J13 jumper enabled; that is, with a jumper installed across the pins labeled J13. To disable Termination Power supply from the disk drive, remove the jumper across the pins labeled J13. PF - Program Flash This jumper is used on drives which support flash programming of drive firmware. This feature is found on early models only. This is not used in the field and should be open, ignore this jumper. SCSI-Bus Device Identification Used in combination, the jumper settings across the SCSI ID reference pins determine the disk drive's SCSI-bus device I.D. SD - Spin Delay At power on or reset the drive motor starts to spin automatically and the drive prepares itself to perform read or write operations. With the Spin Delay feature enabled, at power on or reset the host [SCSI adapter] must send a START/STOP UNIT command to activate the drive motor for read or write operations. Spin Delay allows the drive to perform power sequencing to prevent an overload of the system power supply due to simultaneous, peak start-up current demands from multiple devices. SS - Self Seek With the Self Seek jumper enabled the drive performs, at power on, a continuous seek diagnostic. This diagnostic will not terminate until: 1) Power is removed, 2) SS jumper removed. This feature performs no other function on the drive and should not be used. SY - Spindle Sync Used with disk drives that support synchronized spindle operation. Master or slave synchronized operation is set through a SCSI Mode Select Page. When the drive operates as a Master drive, it generates a spindle synchronization reference signal. When operating as a slave, the drive synchronizes its spindle according to the input reference. The drive always maintains local speed regulation when no reference signal is applied. TE - Termination Enable One of the requirements of the SCSI bus is that it be properly terminated. If more than one SCSI device is connected to the host, only the last device must be terminated. The Terminator Enable (TE) jumper, when installed, enables an active termination circuit, thereby terminating the SCSI bus. With the TE jumper removed, bus termination is disabled. At the factory, Quantum configures the disk drive with termination enabled; that is, with a jumper installed across the termination pins on the corresponding jumper. To disable termination, the jumper must be removed. TP - Termination Power The Termination Power (TP) jumper, when installed, enables termination power to be provided by the disk drive. At the factory, Quantum configures the disk drive with termination power enabled; that is, with a jumper installed across the termination power pins on the corresponding jumper. To disable termination power, remove the jumper. WP - Write Protect This feature, when present, is used to enable write protection on the drive. Installing the WP jumper disables the write feature to the drive and makes the device read only. At the factory, Quantum configures the disk drive with the WP jumper disabled. WS - Wait Spin At power on or reset the drive motor starts to spin automatically and the drive prepares itself to perform read or write operations. With the Wait Spin feature enabled, at power on or reset the host [SCSI adapter] must send a START/STOP UNIT command to activate the drive motor for read or write operations. Wait Spin allows the drive to perform power sequencing to prevent an overload of the system power supply due to simultaneous, peak start-up current demands from multiple devices. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM VIKING II NOTES ON INSTALLATION Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Mounting -------- The mounting holes on the Quantum Viking II 4.55/9.10S hard disk drive allow the drive to be mounted in any orientation. Mounting Screw Clearance ------------------------ Please note that the printed-circuit board assembly (PCBA) is very close to the mounting holes. For mounting #6-32 UNC screws are recommended. Mounting screws should be no longer than 0.22 inches (5.59 mm) and maximum torque applied to the screws must not exceed 14 inch-pounds (1.57 N-m). Clearance from the drive to any other surface (except mounting surfaces) must be a minimum of 0.05 inches (1.25 mm). Shock Clip ---------- The Quantum Viking II 4.55/9.10S hard disk drive comes equipped with a shock clip affixed to one side of the drive. The shock clip provides an extra level of isolation from the occurrence of a short duration non-operational shock, particularly when the drive is mounted on a rigid platform. Note: To prevent the possibility of a cross-threaded screw, it is suggested that the screws associated with the fixed bottom mounting locations be started before the screw associated with the shock clip. It is always good practice to install all the screws completely prior to the final torque process. Ventilation ----------- The Quantum Viking II 4.55/9.10S hard disk drive operates without a cooling fan, provided the ambient air temperature does not exceed 131*F (55*C).
