 Use the J4 connector to set the SCSI ID. To change the SCSI ID,
 install jumpers on the appropriate pins as shown.

 SCSI ID jumpers
 ---------------
 Each device on the SCSI chain must have a unique SCSI ID. The
 host system's SCSI controller usually uses the highest-numbered
 ID available; therefore the lower-numbered SCSI IDs are normally
 used for the other SCSI devices such as this Barracuda disc drive.

 NOTE
 Most SCSI controllers (host adapters) allow you to skip a SCSI ID.
 For example, you can have ID0, ID1, and ID3 (skipping ID2). Other
 controllers do not allow this so be sure to refer to your system or
 controller user's manual for details about its requirements for
 proper SCSI device installation.

 Most Barracuda disc drives are factory set with the SCSI ID set
 at 0. If, after completing the installation process, the drive's
 LED does not show on/off activity when the host is trying to
 communicate with the drive, a duplicate SCSI ID may be the
 problem. If this is the case, change the ID so that each device
 on the SCSI chain has its own unique ID.

 Also check your system or controller user's manual to ensure that
 you have not violated its SCSI ID numbering recommendations.


 WC/DC drives
 ------------
 Setting the SCSI ID jumpers
 The SCSI ID for WC drives is normally set over the SCSI bus by the
 host system using connector contacts 39 (ID0), 40 (ID2), 79 (ID1),
 and 80 (ID3). Systems designers may, optionally, install a remote
 operator panel connection to set the SCSI ID.


 J1 Terminating the drive N/ND
 -----------------------------
 +-------+
 | X * 1 | J1  Enable SCSI terminator (DEFAULT)
 | X * * |
 +-------+
 +-------+
 | * * 1 | J1  Disable SCSI terminator
 | 6 * * |
 +-------+

 If you are installing a Barracuda 2LP drive in a system that has
 other SCSI devices installed, terminate only the end devices on
 the SCSI chain. A SCSI "device" is any disc drive, scanner, tape-
 backup unit, or other piece of hardware connected to your system
 using the SCSI bus.

 N/ND drives
 -----------
 ST31250N and ST32550N drives are terminated with permanently mounted
 IC active terminators. If you install one of these drives and it is
 not on the end of the SCSI bus, disable the terminators by removing
 the jumper from pins 5 and 6 of connector J1. If you install the
 drive on the end of the SCSI bus, enable termination by installing
 a jumper on pins 5 and 6 of connector J1.

 NOTE
 Use active terminators when terminating the bus.

 ST31250ND and ST32550ND drives do not have internal terminators or
 any other way of adding internal termination to the drive. You
 must provide external active termination (ANSI SCSI-2 Alternative
 2) to these drives when termination is required.


 Terminating the drive (W Models)
 --------------------------------
 ST31250W and ST32550W drives are terminated with permanently mounted
 IC active terminators. If you install one of these drives and it is
 not on the end of the SCSI bus, disable the terminators by removing
 the jumper from pins 5 and 6 of connector J1. If you install the
 drive on the end of the SCSI bus, enable termination by installing a
 jumper on pins 5 and 6 of connector J1.

 NOTE
 Use active terminators when terminating the bus.

 ST31250WD and ST32550WD drives do not have internal terminators or
 any other way of adding internal termination to the drive. You must
 provide external active termination (ANSI SCSI-2 Alternative 2) to
 these drives when termination is required.


 Terminating the drive WC Models
 -------------------------------
 ST31250WC and ST32550WC drives do not have internal terminators or
 any other way of adding internal termination to the drive. You must
 provide single-ended external active termination (ANSI SCSI-2
 Alternative 2) to these drives when termination is required.


 Terminator power
 ----------------
 You usually will not need to change this option and can normally
 leave the drive configured as it was shipped from the factory.
 For information about how to change the terminator power option on
 your drive.


 Terminator power W Models
 -------------------------
 There are four possible terminator power configurations for ST31250W
 and ST32550W drives. You will not normally need to change this option
 and can leave the drive configured as it was shipped from the
 factory.

 ST31250WD and ST32550WD drives should be configured with a jumper
 connecting J1 pins 1 and 3 (and no jumper on J1 pins 2 and 4).

 There are four possible terminator power configurations for ST31250N
 and ST32550N drives. You will not normally need to change this option
 and can leave the drive configured as it was shipped from the
 factory.

 ST31250ND and ST32550ND drives should be configured with a jumper
 connecting J1 pins 1 and 3 (and no jumper on J1 pins 2 and 4).

    +-----+---------------+
          + Spindle Sync Ground

 If you are installing two or more Barracuda drives, you may
 (optionally) synchronize their spindles to reduce the latency
 associated with switching from one drive to another. Spindle sync
 cables are used to connect the drives.

 After connecting each drive with spindle sync cables, designate a
 master spindle sync reference source. This master source is normally
 a disc drive located on the same SCSI bus as the other drives you
 want to synchronize with. To designate a drive as the master, use
 SCSI interface commands.


 Synchronizing spindles WC Models
 --------------------------------
 Spindle synchronization for WC drives is normally handled on the
 SSCI bus by the host system using connector contact 37 for the
 spindle sync reference signal. System designers may, optionally,
 install a spindle sync cable using pin 6 on the J4 connector to
 provide +SSREF.

 Enabling write cache
 --------------------
 Write caching is a feature that allows the drive to transfer write
 data to its own cache, tell the controller that the task is complete,
 and then actually complete the write at a later time. This improves
 write performance by freeing the CPU to go on to its next command.

 WARNING
 Information can be lost is you enable write cache and there is a
 system failure (for example, power failure) before the data has
 actually been physically written to the disc.

 OEM drives are shipped with write cache disabled by default. If
 you want to enable the write cache, refer to your system's drive
 controller and software utility documentation. Seagate provides an
 ASPI utility that you can use in a PC compatible system to enable
 the write cache.

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


 Mounting the drive and connecting cables
 ----------------------------------------
 Do not touch the connector pins or any components on the control
 board without observing static-discharge precautions. Always handle
 the drive by the frame only.

 The drive may be mounted in any orientation (horizontally,
 vertically, and any combination thereof); however, you must ensure
 that the drive receives adequate air flow for cooling.

 1. Mount the drive to the host system's chassis using four 6-32
    UNC screws. Two mounting holes are in each side of the drive
    and there are four mounting holes in the bottom of the drive.

    The maximum length that the screws should extend into the chassis
    mounting holes is 0.15 inch (3.81 mm), measured from the outer
    surface of the chassis. Tighten the screws down evenly. Do not
    overtighten or force the screw if it does not seem to screw in
    easily, because this means the threads are not properly aligned.
    In this case, back the screw out and try again.

 2. Verify that all connections between the drive and the host system
    are correctly installed.

 3. Verify that you have correctly installed jumpers.

 4. Connect the 50-pin SCSI cable into the drive's SCSI connector.
    Take care not to stretch or crimp this cable, and do not block
    the system's cooling air flow with the cable.

   The drive receives DC power through a 4-pin connector mounted next
   to the SCSI connector. The output of a power supply must meet SELV
   (safety extra low voltage) as defined in IEC 950. To connect the
   DC power cable to the drive, insert the cable end into the drive's
   DC power connector.

 NOTE
 Signal ground on the power control board (PCB) and the head and
 disc assembly (HDA) are connected together in this drive and you
 cannot separate them. The equipment in which you have mounted the
 drive is connected directly to the HDA and PCB without electrically
 isolating shock mounts. Maximizing the conductive contact area
 between HDA ground and system ground may reduce radiated emissions.
 If you do not want the system chassis to be connected to the HDA/PCB
 ground, you must provide a nonconductive (electrically isolating)
 method of mounting the drive in the host system. This may increase
 radiated emissions and is the system designer's responsibility.

 5. Replace the host system's cover.

 This mounting procedure does not apply to WC or DC model drives!
 To mount a WC or DC drive, plug the drive into the system's single
 connector attachment (SCA) position on the system's back panel.


 Providing adequate cooling
 --------------------------
 The enclosure design must ensure adequate cooling for the drive.
 The maximum ambient temperature is 50*C.

 We recommend orienting the drive or directing the air flow in a
 way that creates the least amount of air-flow resistance while
 providing air flow above the circuit boards and around the head and
 disc assembly (HDA). Also, choose the shortest possible path between
 the air inlet and exit. This minimizes the distance traveled by air
 that is heated by the drive and by other nearby heat sources.

SEAGATE  ST31250/32550N/ND/W/WD/WC/DC INSTALL.GUIDE 83328920, REV. E

 Preface
 -------
 This manual contains information for users of the Seagate ST31250
 and ST32550 Barracuda 2LP SCSI disc drives. It provides support
 services, performance specifications, and initial setup information.
 Additional information is available in the Barracuda 2LP Product
 Manual (part number 83328930). Contact your Seagate sales
 representative if you need to order this publication.


 Electrostatic discharge protection
 ----------------------------------
 Caution.
 Removal of circuit boards by personnel not performing depot
 repair will damage components and may void the warranty.

 All drive electronic assemblies are sensitive to static electricity,
 due to the electrostatically sensitive devices used within the drive
 circuitry. Although some devices such as metaloxide semiconductors
 are extremely sensitive, all semiconductors, as well as some
 resistors and capacitors, may be damaged or degraded by exposure
 to static electricity.

 Electrostatic damage to electronic devices may be caused by the
 direct discharge of a charged conductor or by exposure to the
 static fields surrounding charged objects. To avoid damaging drive
 electronic assemblies, observe the following precautions when
 installing or servicing the drive:

 - Ground yourself to the drive whenever the drive electronics are
   or will be exposed. Connect yourself to ground with a wrist strap
   (Seagate part number 12263496). Connection may be made to any
   grounded metal assembly. As a general rule, remember that you and
   the drive electronics must all be grounded to avoid potentially
   damaging static discharges.

 - Turn off the power before removing or installing the DC power
   cable.

 - Do not remove any circuit boards from the drive.

 - Never use an ohmmeter on any circuit boards.

 - When installing the drive on a carrier or tray, discharge the
   static electricity from the carrier or tray prior to inserting it
   into the system.


 Important safety information and precautions
 --------------------------------------------
 Caution. Use forced-air ventilation when bench testing the drive to
 ensure proper cooling of drive components.

 Use proper safety and repair techniques for safe, reliable operation
 of this unit. Service should be done only by qualified persons.

 The procedures in this manual and labels on the unit contain warnings
 and cautions that must be carefully read and followed to minimize or
 eliminate the risk of personal injury. The warnings point out condi-
 tions or practices that may endanger you or others. The cautions
 point out conditions or practices that may damage the unit, possibly
 making it unsafe for use.

 Always observe the following warnings and precautions:

 - Perform all maintenance by following the procedures in this manual.

 - Follow all cautions and warnings in the procedures.

 - Use sound safety practices when operating or repairing the unit.

 - Use caution when troubleshooting a unit that has voltages present.
   Turn off power to the unit before servicing it.

 - Wear safety shoes when removing or replacing heavy parts.

 - Ensure that the internal temperature of the rack or cabinet does
   not exceed the limits defined for the drive when the drive is
   mounted in an equipment rack or cabinet. When units are stacked
   vertically, pay special attention to the top where temperatures
   are usually highest.

 - Do not remove any circuit boards from the drive chassis. Return
   the entire drive for depot repair if any circuit board is
   defective. Removal of circuit boards by personnel not performing
   depot repair will damage components and may void the warranty.

 - Do not remove the head and disc assembly (HDA) from the drive
   chassis. Return the entire drive for depot repair if the HDA is
   defective.

 - Do not attempt to disassemble the HDA. It is not field repairable.
   If the sealed HDA is opened by personnel not performing depot
   repair, this will damage compo-nents and void the warranty.

 As a component, this drive is designed to be installed and operated
 in accordance with UL1950, IEC950, EN60950, CSA C22.2 950, and
 VDE0805.

 Typical applications of these disc drives include customer packag-
 ing and subsystem design. Safety agencies conditionally certify
 component assemblies, such as the Barracuda disc drive, based on
 their final acceptability in the end-use product. The subsystem
 designers are responsible for meeting these conditions of accept-
 ability in obtaining safety, regulatory agency compliance in their
 end-use products and for certifying where required by law. A
 necessary part of meeting safety requirements is the provision
 for overcurrent protection on drive SELV supply voltages.

 This unit is a component part and as such is not meant to comply
 with FCC or similar national requirements as a standalone unit.
 Engineering radiated emissions test results are available through
 the Seagate Safety Department to assist the subsystem designer.


 General description
 -------------------
 Barracuda 2LP SCSI disc drives are high-speed, randomaccess digital-
 data storage devices.

 The drive is a component for installation in an enclosure designed
 for the drive. This is often a rack within the system or an external
 enclosure designed to house one or more disc drives or other
 peripheral units. In either case, the disc drive must receive
 adequate cooling and it must be sufficiently grounded and
 shielded from emissions. The Barracuda 2LP Product Manual (part
 number 83328930) contains guidelines for a properly designed
 enclosure.
