 The jumpers control SCSI Device ID, Auto Spin Up, Unit Attention,
 SCSI Terminator Connection, Target Initiated Synchronous Negotiation
 and the LED Driver Output.

 Notes: 1. The jumper position of JP1, 2, and 3 define SCSI ID of the
 drive
 If JP1,JP2,JP3 are Off, Off, Off the SCSI ID is 0
 If JP1,JP2,JP3 are On,  Off, Off the SCSI ID is 1
 If JP1,JP2,JP3 are Off, On,  Off the SCSI ID is 2
 If JP1,JP2,JP3 are On,  On,  Off the SCSI ID is 3
 If JP1,JP2,JP3 are Off, Off, On  the SCSI ID is 4
 If JP1,JP2,JP3 are On,  Off, On  the SCSI ID is 5
 If JP1,JP2,JP3 are Off, On,  On  the SCSI ID is 6 (shipping default)
 If JP1,JP2,JP3 are On,  On,  On  the SCSI ID is 7

 2. If JP4 is Off, the drive will spin up automatically after power on
                   reset.
    If JP4 is On,  the drive will not spin up unless the host system
                   issues a start command to the drive.

 3. If JP5 is On,  Unit Attention after power on reset or SCSI bus
                   reset is disabled.

 4. If JP6 is On,  the internal SCSI active terminator works.

 5. If JP7 is On,  Target Initiated Synchronous Negotiation is
                   disabled, and then the Initiator is required to
                   start a negotiation handshake if Synchronous SCSI
                   transfers are desired.

 6. Jumpers JP8, JP9, JP10 and JP11 are not used.

 7. Jumper JP12 can be used to drive a LED for SCSI Busy. Pin 24 is
    +5V, and Pin 23 will drive a load up to 8mA.

 The drive will operate in all axis (6 directions).

 The maximum allowable penetration of the mounting screws is 6 x 3,5mm
 or 4 x 6 mm. The recommended mounting screw torque is 6 to 10kgF.cm
 (0.6-1.0Nm).

  -+  +------------+|  pin 3    + 5 Volts Return
  ------------------+  pin 4    + 5 VDC


 Connectors
 ----------
 The DC power connector is designed to mate with AMP part 1-480424-0
 (using AMP pins P/N 350078-4). Equivalent connectors may be used.

 The SCSI Signal Connector is a 50 pin connector meeting the ANSI SCSI
 specification. Note: It is intended that the hard disk drive should
 only be in electrical contact with the chassis of the PC at a
 designated set of mounting holes. Other electrical contact may
 degrade error rate performance. As a result of this it is recommended
 that there should be no metal contact to the hard disk drive except
 at the mounting holes or the side rails into which the mounting holes
 are tapped.


 DC Power Requirements
 ---------------------
 The following voltage specifications apply at the drive power
 connector. Damage to the drive electronics may result if the power
 supply cable is connected or disconnected while power is being
 applied to the drive (No hot plug/unplug is allowed). There are
 inductive loads in the drive which could cause destructively high
 voltage spikes on the drive if the power connection is opened. There
 is no special power on/off sequencing required.

 Nominal Supply
 Voltages                +5 volts      +12 volts
 Power Supply Ripple
 {mV}(0-10{Mhz}P-P)      100 max       150 max
 Voltage Supply
 Tolerance (incl. ripple) +/-5%        +10%/-8%

 Power Supply
 Current
  Start up (Peak)         0.51A        1.16A
  Idle (average)          0.23A        0.12A
  R/W (average)           0.57A        0.14A
  Seek (average)          0.41A        0.27A
  Standby                 0.20         0.01A

 During the drive start up and seeking, 12 volt ripple is generated by
 the drive (referred to as dynamic loading). If several drives have
 their power daisy chained together then the power supply ripple plus
 other drive's dynamic loading must remain within the regulation
 tolerance of +10/-8%. A common supply with separate power leads to
 each drive is a more desirable method of power distribution.

 To prevent external electrical noise from interfering with the
 drive's performance, the drive must be held by four screws in a user
 system frame which has no electrical level deference at the four
 screws position, and has less than +/-300 millivolts peak to peak
 level deference to the drive power connector ground.

 45 Ground       46 -C/D
 47 Ground       48 REQ
 49 Ground       50 -I/O


 SCSI cable
 ----------
 The disk drive uses single-ended drivers and receivers which will
 permit cable lengths of up to 6 meters (19.68 feet). For a single
 ended cable a 50 conductor flat cable or a 25 signal twisted cable
 can be used with a maximum length of 6.0 meters, and a stub length
 not exceeding 0.1 meters.


 SCSI BUS Terminator
 -------------------
 The file has an internal Active SCSI bus terminator, and can be
 controlled on/off with one jumper block provided at the card edge.
 The user is responsible for properly terminating and powering the
 SCSI bus in the system.

 -----------------------------
 The drive meets the following EMC requirements when installed in the
 user system and exercised with a random accessing routine at maximum
 data rate: United States Federal Communication Commission (FCC) Rules
 and Regulations Part 15, Subject J Computer Devices "Class B Limits".
 European Economic Community (EEC) directive #76/889 related to the
 control of radio frequency interference and the Verband Deutscher
 Elektrotechniker (VDE) requirements of Germany (GOP).


 WARNING: This disk drive can be damaged by Electro-Static Discharge,
 please follow recommended ESD procedures before unpacking or handling
 the drive. Ask your dealer for details if you need assistance.

 PACKAGING: The drive must be protected against Electro-Static
 Discharge especially when being handled. The safest way to avoid
 damage is to put the drive in an anti static bag before ESD wrist
 straps are removed. Drives should only be shipped in approved
 containers, severe damage can be caused to the drive if the packaging
 does not adequately protect against the shock levels induced when a
 box is dropped. Consult your IBM marketing representative if you do
 not have an approved shipping container.
