 Jumper Setting
 ==============

 J1 Option Jumper
 ----------------
 The MK-438FB and MK-53XBF have one jumper block, J1 (use 2mm jumper
 part numbers: P/N 037001 [Toshiba] or P/N 86730-001 [Dupont].

 CAUTION
 Manufacturing pin location is for factory use only. If jumper is
 installed, data will be destroyed on drive.

 MANUFACTURING ENABLE (J1-PIN 1&2) - CAUTION FACTORY USE ONLY

 UNIT ATTENTION ENABLE (J1-PINS 3&4) - PRESENT WHEN SHIPPED
 Removal will inhibit ubit attention at power on or SCSI reset.

 START ON COMMAND ENABLE (J1-PINS 5&6) - PRESENT WHEN SHIPPED
 When removed the spindle motor will start only on receipt of the
 Start Unit command.

 SCSI BUS PARITY ENABLE (J1-PINS 7&8) - PRESENT WHEN SHIPPED
 When removed, drive will not check for parity.

 SPINDLE SYNCHRONIZATION (J1-PINS 9-12) - PINS 11&12 NOT PRESENT WHEN
 SHIPPED SPARE JUMPER LOCATED AT PINS 9&10 WHEN SHIPPED
 Spindle Synchronization capability accommodated using a 4-pin cable
 connector (pins 9 - 12 of jumper block).

 TERMINATOR POWER SOURCE (J1-PINS 13&14) - PRESENT WHEN SHIPPED
 When removed, drive does not supply terminator power. The SCSI BUS
 requires termination to be installed on the last unit located on the
 BUS. There are two versions of the PCB. One version use three (3) SIP
 Resistors (RN1, RN2 & RN3) to provide BUS termination. The other
 version uses a SCSI in-line cable terminator (this terminator is
 shipped with the drive in a separate bag).

 EXTERNAL LED (J1-PINS 15&16) - NOT PRESENT WHEN SHIPPED
 An external LED may be driven by connecting the cathode to pin 16 and
 the anode to pin 15 on the jumper block.

 SCSI BUS ID (J1 PINS 17-22)
 Jumper J1, pins 17-22, are used to select the SCSI ID of the drive.
 The drive can be selected to have any ID in the range 0 through 7. No
 two devices on the same SCSI bus can have the same ID.

   +----------+-----------------------+
   | SCSI ID  | 17&18   19&20   21&22 |
   |          | ID2   | ID1   | ID0   |

 Notes on Installation
 =====================

 Mounting
 --------
 When mounting the drive, adequate clearance should be provided from
 the outer surface of the HDA and PCB to allow vibration to be ab-
 sorbed by the drive shock mounts and to allow for the passage of
 cooling ir over the drive.

 WARNING
 The side mounting screw must not penetrate into the drive frame more
 than 0.10 inches (2.5mm) or damage to the HDA will result. Length of
 screw = Thickness of mounting material + 0.05 - 0.10 inches. Typical
 screw length for most applications is 3/16". (A washer should be used
 to meet non-standard screw length requirements.)


 Cooling and disk drive enclosure
 --------------------------------
 The MK-438FB and MK-53XFB can be mounted vertically or horizontally.
 Convection cooling is used. It is recommended that cabinetry design
 allow for adequate air flow. The disk enclosure must be designed to
 maintain an even temperature within the drive's environmental limits
 and throughout the drive's various components.


 Terminator Resistors
 --------------------
 The resistors must be removed on all but the last physical device on
 the SCSI BUS.


 Optional Hard Disk Drive Kits
 -----------------------------
 If desired, an optional 3.5" hard drive mounting kit (P/N HDD002KU)
 is available for mounting the hard drive in a 5.25" half height
 cavity. Also available are PC/AT mounting rails (P/N AT8001T).

 The following accesories are available:

 P/N 290000003-A0  SCSI ID cable for remote selection of ID
 P/N CAB-01-24     SCSI 50 Pin Flat Ribbon Cable
 P/N 140-001       External SCSI Bus single-ended terminator
                   (Method Electronics, Inc. P/N SP-550-06-0)
 P/N 270008-A1     LED extension cable assembly

 Versions of ONTRACK's DiskManager for DOS, Macintosh operating
 systems and DiskManager-N for Novell Network systems can be used with
 this drive.


 General Description
 -------------------
 The MK-438FB and MK-53XFB series consist of 3.5-inch hard disk drives
 designed primarily for high performance personal computers such as
 IBM PC/AT or compatible, Apple Macintosh and Sun Micro Work Stations.

 CAUTION
 Please use caution when handling and installing drive. Avoid
 excessive shock, vibration and static build up in the installation
 environment. The MK-438FB and MK-53XFB are precision devices, do not
 drop drive onto a surface. Until drive is mounted in your system, its
 built in shock absorbers are inactive and even a small drop may
 cause permanent damage.
