Jumpers

QUANTUM VIKING II JUMPER SETTING

Jumper Settings
----------------

SCSI Disk Jumper Definitions
----------------------------
Quantum SCSI disk drives have multiple jumper setting options
and are used to set specific drive features. 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.

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).
