The host system's SCSI controller usually uses the ID that has the highest priority in the SCSI I/O system. This is always ID7. ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority in a 16-bit I/O system. The lower priority SCSI IDs are normally used for other SCSI devices such as this Medalist 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. Note. This drive is a SCAM (SCSI Configured Auto Magically) compliant drive. If the system into which you are installing this drive requires SCAM compliant drives, you do not need to be concerned about the drive ID jumper settings, as the system automatically assigns your new drive the ID it wants it to have. The system may or may not use the existing drive ID jumper settings. Setting the drive ID doesn't hurt anything, but is not necessary in a SCAM compliant system. The Medalist disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, refer to the appropriate drive section for your model. 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. Drive termination ----------------- If you are installing a Medalist 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. Note. Some controllers prefer to remain terminated even if they are in the middle of the chain. Also, some controllers treat the internal and external chains as separate logical buses. This means you may need to terminate both the first and last devices on both logical buses to achieve proper termination. If necessary, refer to your system or controller documentation to see how this is handled in your particular system. 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, refer to the appropriate drive-specific section. I/O circuits and data path widths W and WC models have a wide (16-bit) SCSI data bus rather than the standard (non-wide) 8-bit SCSI data bus; however, you can use these wide drives on a standard (non-wide) 8-bit data bus using a terminated 68-pin to 50-pin SCSI cable. For devices having differential I/O circuits, a maximum cable length of 25 meters (82 feet) is allowed. A maximum of 8 devices can be connected on an 8-bit wide data bus, and a maximum of 16 devices can be connected on a 16-bit wide data bus. N drives --------- Terminating the drive N model 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 TE from pins 15 and 16 of connector J2. If you install the drive on the end of the SCSI bus, enable termination by installing a jumper on pins 15 and 16 of connector J2. Terminator power ---------------- There are four possible terminator power (TP) configurations for N model drives. You will not normally need to change this option and can leave the drive configured as it was shipped from the factory. W/WD drives section Setting the SCSI ID jumpers ----------------------------------------------- Use the J6 jumper block to set the SCSI ID. To change the SCSI ID, install jumpers on the appropriate pins. Optional connections to switching circuits in host equipment are provided on J1 auxiliary to set the SCSI ID. Terminating the drive --------------------- W model 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 TE from pins 15 and 16 of connector J2. If you install the drive on the end of the SCSI bus, enable termination by installing a jumper on pins 15 and 16 of connector J2. Note. Use active (ANSI SCSI-2 Alternative 2) terminators when terminating the bus. Terminator power ---------------- There are four possible terminator power (TP) configurations for W model drives. You will not normally need to change this option and can leave the drive configured as it was shipped from the factory. WC drives ---------- WC/DC drives section Setting the SCSI ID jumpers The SCSI ID for WC model drives is normally set over the SCSI bus by the host system using connector contacts 39 (ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Users need not install jumpers to select SCSI ID. Terminating the drive --------------------- WC model drives do not have internal terminators or any other way of adding internal termination to the drive. External termination for these drives is normally supplied by the host equipment when termination is required.

Providing adequate cooling -------------------------- The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50*C. The drive's product manual (32661-001) describes how to evaluate the air-flow design. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation. 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. The air-flow patterns can be created by the fans either pushing or drawing air. The overall flow pattern can be directed from front to back, back to front, or side to side. 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. 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. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST39140N/W/WC JUMPER SETTING 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 metal-oxide semi- conductors 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 carrier or tray prior to inserting it into the system. Important safety information and precautions -------------------------------------------- Caution. Use forced-air ventilation when benchtesting the drive to ensure proper cooling of drive components. Use proper safety techniques for safe, reliable operation of this unit. 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 conditions or practices that may endanger you or oth-ers. 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: - Follow all cautions and warnings in the procedures. - Use sound safety practices when operating, installing, or removing the unit. - Use caution when troubleshooting a unit that has voltages present. Turn off power to the unit before removing it. - 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. - Follow the precautions listed above in Electrostatic discharge protection. - Do not remove any circuit boards from the drive. 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. 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 components and void the warranty. As a component, this drive is designed to be installed and operated in accordance with UL1950, EN60950, CSA C22.2 950- M89, and VDE0805. Seagate takes all reasonable steps to ensure that its products are certifiable to currently accepted standards. Typical applica- tions of these disc drives include customer packaging and subsystem design. Safety agencies conditionally certify component assemblies, such as the Medalist disc drive, based on their final acceptability in the enduse product. The subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety- regulatory agency compliance in their enduse 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 stand-alone unit. Engineering radiated emissions test results are available through the Seagate Safety Department to assist the subsystem designer. General description ------------------- Medalist Pro SCSI disc drives are highspeed, 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. Formatting the drive -------------------- Warning. Formatting a drive erases all user data. Be sure that you understand this principle before formatting any hard disc drive. It is not necessary to format a drive that previously has been used to store data, unless your intention is to erase all user data. Note. Seagate is not responsible for lost user data. 1. Turn on DC power. 2. Boot the system from a system floppy disc or from a previ-ously installed hard disc drive if there is one. 3. Format the disc drive. Medalist Pro disc drives are designed to operate with a variety of operating systems. Please refer to your system or SCSI controller manual for information about formatting and setting up the drive.
