When configured for Auto-Startup, the motor spins up after power is applied without the need of a SCSI Start Unit command. For no Auto-Start, a SSI Start Unit command is required to make the drive spin and be ready for media access operations. When in Auto-Start mode, the drive will delay it's start time by a period of time multiplied by it's own SCSI address. +----------+----------+----------+-----+ |Auto Start|Auto Start|Auto-Start|Delay| |Delay | |Mode ? |(sec)| +----------+----------+----------+-----+ |OPEN |OPEN |NO | NA | |OPEN |CLOSED |YES | 0 | |CLOSED |OPEN |YES | 10 | |CLOSED |CLOSED |YES | 4 | +----------+----------+----------+-----+ LED Pins -------- The LED pins be used to drive an external Light Emitting Diode. Up to 33 mA ( 5%) of TTL level LED drive capability is provided. NOTE This set of pins can be used to drive an LED located in a bezel connected to the front of the drive or to an external LED in systems where the front of the drive can not be easily seen. NOTE 68 pin SCSI models have two sets of pins, a set on the front and a set on the back, that are connected to the same LED driver circuit. The combined drive capability is stated above. Write Protect Pins ------------------ If the Write Protect pin is jumpered to ground the drive will inhibit SCSI commands that alter the customer data area portion of the media from being performed. Disable T.I.Sync. Negotiation Pins ---------------------------------- If a Disable Target Initiated Synchronous Negotiation pin is grounded then an Initiator is required to start a negotiation handshake if Synchronous SCSI transfer are desired. Disable SCSI Parity Pins ------------------------ Grounding this pin will disable SCSI Parity checking. Disable Unit Attention Pins --------------------------- Grounding this pin will disable the drive from building Unit Attention Sense information for commands immediately following a Power On Reset (POR) or SCSI Bus Reset. Any pending Unit Attention conditions will also be cleared at POR or SCSI Reset times. Customizing Pins ---------------- The customizing pins and their associated jumper pins are currently reserved for future use. They are for features specific to particular host systems that must be in affect immediately after power is applied to the drive. Please contact your IBM Customer Representative for functional details on other using system specific features that these pins could possibly be used for. SCSI Bus Termination Power -------------------------- Termination Power is optionally provided for systems that desire to use it. In order to use the termination power, the user needs to install a jumper between pins A01 and A02 of the TermPower Block. The jumper should only be installed on one device, which should be the last device on the SCSI bus (i.e. the drive that is phydically closest to a terminator). 68 pin models can source up to 2.0 Amps of current at 5.0 Volts ( 5%) for termination power. 50 pin models can source up to 1.5 Amps of current at 5.0 Volts ( 5%) for termination power. ********************************************************************** I N S T A L L ********************************************************************** IBM 0662-S12/S1D/SW1/SWD SPITFIRE 41K.011, VER. 2.1, 4/12/1993 Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Mounting -------- The drive can be mounted with any surface facing down. The drive is available with both side and bottom mounting holes. The maximum allowable penetration of the mounting screws is 3.8 mm. The torque applied to the mounting screws must be 0.8 Newton-meters 0.1 Newton-meters. WARNING Except for the isolated mounting holes, the body of the file is not at ground potential. Therefore any user mounting scheme must not re- sult in the file being shorted to ground. The file may be sensitive to user mounting implementation due to file distortion effects. IBM will provide technical support to assist users to overcome mounting sensitivity. Clearances ---------- A minimum of 2 mm clearance should be given to the bottom surface except for a 10mm diameter area around the bottom mounting holes. For proper cooling it is suggested that a clearance of 6 mm be provided under the file and on top of the file. There should be 7 mm of clearance between the files that are mounted with their top sides facing each other. Power Connector --------------- The DC power connector is designed to mate with a Molex 8981-4P4 crimp connector, or a Molex A-70156-2000 insulator displacement connector, or their equivalent. +------------+ pin 1 +12 VDC | 4 3 2 1 | pin 2 +12 Volts Return +------------+ pin 3 + 5 Volts Return pin 4 + 5 VDC 50-Pin SCSI Bus Connector ------------------------- 50-pin models use a Hirose MIF62B-54PB-2.54DS(02) connector on the SMD versions of the electronics circuit board and a Hirose MIF62C- 54PB-2.54DS on the SMP versions of the electronics. They are both compatible with the ANSI SCSI-2 "A" connector specifications. It is limited to 8 bit data transfers only. 68-Pin SCSI Bus Connector ------------------------- 68-pin models use an AMP 92-8012-16-1 connector that is compatible with the ANSI SCSI-3 "P" connector specifications. It can transfer data in both 8 bit (narrow) and 16 bit (wide) modes. NOTE Note that the "P" connector is not mechanically compatible with the 50-pin "A" connector as defined in the ANSI SCSI-2 standard. Therefore system cables used with 50 pin products cannot be plugged directly into the 68 pin models. Despite the difference in connector, the differential 68-pin models are electrically compatible with differential 50-pin models and other 50-pin differential SCSI products and therefore can coexist on the same bus. In order to do so, the differences in connector types would need to be accounted for in the cable. The same can be said for connecting 68 and 50 pin single-ended models to the same bus. But differential and single-ended models do not work connected to the same bus. SCSI Bus Cable -------------- Single-ended models permit cable length of up to 6 meters (19.68 feet). It should be noted however that users who plan to use "Fast" data transfers with single-ended models should follow all of the SCSI-3 guidelines for single-ended "Fast" operations. This may include a cable length of less than 6 meters. Differential models permit cable length of up to 25 meters (82.02 feet). Cables must meet the requirements for differential cables as set forth in the ANSI SCSI-2 standard under "Cable Requirements - Differential Cable". The SCSI-2 standard states that any stub from main cable must not exceed 0.1 meters for single-ended cables and 0.2 meters for differential cables. SPITFIRE has a maximum internal stub length of 0.053 meters on all SCSI signals. To remain compliant with the standard, the SCSI bus cable must not add more than 0.047 meters additional stub length to any of the single-ended SCSI signals or .147 meters to any differential SCSI signals. SCSI Bus Terminators -------------------- Single-Ended models have internal SCSI bus active terminators that can be enabled by installing a jumper between pins 13 and 14 of the Front Options Jumper Block or pins 7 and 8 of the Rear Block on 68 pin models. The using system is responsible for making sure that all required signals are terminated at both ends of the cable. Differential models do not have internal SCSI bus terminators. Some terminator possibilities are listed in the following Table. +-------------------------+-------------------------+ |50 Pin Model Terminators | 68 Pin Model Terminators| +-------------------------+-------------------------+ |Data Mate DM550-05-0 | Data Mate DM2050-01-68D | |Data Mate DM1050-02-0 | | +-------------------------+-------------------------+ Recommendations For SCSI Bus Noise Reduction -------------------------------------------- The SCSI commitee has spent a large amount of resource looking into what needs to be done to assure SCSI devices will work as specified in the SCSI-2 standard. As a result of this, the committee is recommending the following approach: 1. Use the regulated 110 ohm terminator 2. Use AWG 28 polyolefin shielded cables 3. Make sure data and parity are on the outer ring of the cable and that REQ and ACK are in the core of the cable. SCSI Bus Electrical Characteristics ----------------------------------- The following DC operating characteristics pertain to the single- ended SCSI bus transceivers. All of these parameters meet the ANSI SCSI-2 requirements. Ta = 0 to 70 deg.

The following paragraphs give a short description of each spindle synchronization mode: - The Slave drive (Slave Sync mode) receives the index from the Master drive on the -SLAVE SYNC line and synchronizes its INDEX (Slave index) to it. - Should the drive be the Master drive, (Master Sync mode), it out- puts its INDEX on the -MASTER SYNC and the -SLAVE SYNC lines. The Master drive does not synchronize its index to any other device. It simply outputs its INDEX. - In the Master Sync Control mode, a drive will synchronize its spindle to the signal it receives on the -SLAVE SYNC input. It out- puts to -MASTER SYNC a pulse that has the same period as the drive INDEX, but is not synchronized to the drive INDEX generated from the disk. - In the non-sync mode, the file will receive the -Slave SYNC signal, but it is not used by the file. Spindle Synchronization Control Lines +------------+-----------+-------------------+ |-MASTER SYNC|-SLAVE SYNC|function mode | +------------+-----------+-------------------+ |released |receive |Slave sync | +------------+-----------+-------------------+ |drive |drive |Master sync | +------------+-----------+-------------------+ |drive |receive |Master Sync Control| +------------+-----------+-------------------+ |released |receive |non sync | +------------+-----------+-------------------+ - File Synchronization with Offset The file electronics receives the Master Index and creates the delayed Slave Index from the drive INDEX. The delay is determined by using the Mode select command, Rigid Disk Drive Geometry Parameters (page 4). A rotational offset of 0/256 of a revolution up to 255/256 of a revolution may be selected in increments of 1/ 256 of a revolution. - Synchronization Time The SCSI MODE Slect command is used to select the Spindle Sync. mode. It could take up to 1.75 seconds (1.25 sec. nominally) to synchronize the Slave drive to the Master drive. While the Slave drive is synchronizing to the Master, it will not be able to read and write data. Once synchronized, the drive will maintain 20 usec synchronization tolerance. Spindle Synchronization Bus --------------------------- The spindle synchronization Bus consists of the two signal lines, -MASTER SYNC and -SLAVE SYNC. - Termination Bus termination of the -MASTER SYNC and -SLAVE SYNC signals is internal to the file. These two signals each have a 2000 ohm pullup to the +5 volt supply. A maximum of 16 files can have their -MASTER SYNC or -SLAVE SYNC lines daisy chained together. Violating this could damage the Master file driver on the -MASTER SYNC and/or -SLAVE SYNC line. - Bus Characteristics - maximum Bus length = 6 meters - 4 micro-seconds negative active pulse - 0.8 volts = valid low input - 2.0 volts = valid high input - 0.4 volts = low output - 64 milli-amps = maximum output low level sink current - high level output set by termination resistors The driver used for these two signal lines is an open collector buffer. Hot plug/unplug support ----------------------- Power supply and SCSI bus hot plug and un-plug is allowed. There is no special sequence required for connecting 5 volts, 12 volts, or ground. During a hot plug-in event the file being plugged will draw a large amount of current at the instant of plug-in. This current spike is due to charging the bypass capacitors on the file. This current pulse may cause the power supply to go out of regulation. If this supply is shared by other files then a low voltage power on reset may be initiated on those files. Therefore the recommendation for hot plugging is to have one supply for each file. Never daisy chain the power leads if hot plugging is planned. Hot plugging should be minimized to prevent wear on the power connector. Hot plugging the SCSI bus may cause glitches on the bus. To minimize the chance of glitching, it is recommended to plug in the SCSI bus before the power is applied. During hot plugging, the supplies must not go over the upper voltage limit. This means that proper ESD protection must be used during the plugging event. During hot-unplugging if th eoperation shock limit specification can be exceeded then the file should be issued a SCSI Stop Unit command which is allowed to complete before un-plugging. ********************************************************************** F E A T U R E S ********************************************************************** IBM 0662-S12/S1D/SW1/SWD SPITFIRE 41K.011, VER. 2.1, 4/12/1993 Features -------- - Industry-standard interface: ANSI/SCSI-2, single-ended (optional 68 pin from SCSI-3) - Thermal compensation on each data surface for improving on track positioning capability. - SCSI disconnect and reconnect capability - Magnetoresistive (MR) heads - May be ordered with or without a bezel - SCSI bus parity - Multiple initiator support - Closed-loop actuator servo (dedicated disk servo surface plus data reference) - Rotary voice coil motor actuator - Automatic actuator latch - Dedicated head landing zone - (0.4/4) 8/9 rate encoding - read-ahead caching - Tagged and Untagged command queuing - Command reordering - Back-to-back writes - Automatic sector reallocation - Error logging and analysis - Variable logical block length (512-744 supported) - Down-loadable SCSI firmware - Buffer memory parity - Self-diagnostics on power up - Automatic retry and data correction on read errors - In-line alternate sector assignment for high performance - Probability of not recovering data: 1 in 10(15) bits read - All mounting orientations supported - No preventative maintenance required - Two field Replaceable Units (FRU's:): Electronics and HDA - Predictive Failure Analysis - Spindle synchronization - LED driver - Write cache supported (delayed write) - Automatic power management - SCSI behavior cutomizing jumpers - Longitudinal Redundancy Code (LRC) - ECC on the fly - Deep Data Recovery Procedures (DRP) Thermal Compensation -------------------- The drive periodically compensates certain all heads to account for movements caused by thermal changes. The compensation process is initiated automatically by the drive. The compensation of one head is called a process. A process is started every 36 sec during the first hour after power is applied, and every 3 minutes thereafter. Of that process period, 210 msec is actually spent compensating a head. Multiple SCSI commands are accepted and executed without delay during a compensation process if the commands are received less than 50 msec after the completion of the previous SCSI command. There is one exception. If a head due to be compensated is not compensated within the process period (due to the rapid arrival of SCSI commands and/or commands that take a large amount of time to execute relative to a process period), then the drive delays SCSI non-Priority commands, except for Test Unit Ready, from executing until that one head is compensated. This scheme insures that each head is compensated at least every 3 minutes during the first hour after spin up, and every 15 minutes thereafter. The intent of the scheme is to minimize the negative effects of compensation on drive performance. Seek Time --------- +----------------------------------+--------+ |Single cylinder (read) msec. | 0.6 | +----------------------------------+--------+ |Single cylinder (write) msec. | 2.5 | +----------------------------------+--------+ |Average msec. typ. | 8.8 | |Full stroke (write) msec. | 18 | +----------------------------------+--------+ |Latency msec. avg. | 5.56 | +----------------------------------+--------+ SCSI Data Transfer Rate ----------------------- The SCSI data transfer rate is dependent on the mode, either synchronous or asynchronous. It also depends upon the width of the data path used. 8 and 16 bit transfers are supported. When the drive is configured for an 8 bit wide synchronous data transfer rate of 10 MB/sec (instantaneous), the average SCSI data transfer rate is realized will be at least 9.2 MB/sec. The 16 bit transfer rates are 20 MB/sec and 18.4/sec respectively. The asynchronous data transfer rate is dependent on both the initiator and target delays to the assertion and negation of the SCSI REQ and ACK signals. It is also dependent on SCSI cable delays. The drive is capable of supporting up to 5 MB/sec asynchronous data transfer rates. The SCSI data transfer rate specification only applies to the Data phase for logical block data for Read, Write, Write and Verify, etc. commands. The data rate for parameter/sense data Request Sense, Mode Select, etc... commands is not specified.

Support for Other Block Lengths ------------------------------- A new release of the SCSI Interface code is required to support block lengths less than 512 or greater than 744 bytes. A new SCSI Interface Processor code release will be made available as the business requires. Please contat your IBM Customer Representative if you have requirements for block lengths other than 512-744. SCSI Bus Termination Power Short Circuit Protection --------------------------------------------------- The ANSI SCSI-2 specification recommends for devices that optionally supply TERMPWR, to include current limiting protection for accidental short circuits. It also recommends that the maximum current available for TERMPWR should not exceed 5 Amps. UL has a different requirement that they call the 8 Amp rule. This rule states that when a power source leaves an enclosure (like SCSI TERMPWR in the SCSI cable), it must trip 8 Amps of current within 1 minute. SPITFIRE uses a resettable "Positive Temperature Coefficient" (PTC) resistor for TERMPWR short circuit protection. These devices will trip when they are over-heated due to excess current flowing through them. When the over current condition (i.e. current surge due to a hot plug or intermittent short, or a solid short circuit) is removed, the device can automatically reset, allowing TERMPWR to again be sourced from this device. SPITFIRE complies with the 8 Amp UL requirements. For systems that prefer to comply with the SCSI-2 5 Amp recommended TERMPWR limit, the 5 Volts power supplied to SPITFIRE should be limited to prevent TERMPWR from exceeding 5 Amps. This would prevent a current surge in excess of 5 Amps that may occur in the event of a short circuit, before the PTC device can actually trip. ********************************************************************** G E N E R A L ********************************************************************** IBM SCSI INSTALLATION SCSI Installation Guide Generic Installation requirements ------------------------- To install a drive inside your computer or in an external storage enclosure for SCSI devices, you must have: 1 The documentation that came with your computer or storage enclosure. 2 The documentation that came with your hard drive. 3 A small, flat blade screwdriver. 4 A SCSI controller, which is either built into the system board or on an adapter inside your computer. 5 An installation kit, if it is required for your computer. Contact your place of purchase if you are not sure. 6 If you are installing this into a PS/2 computer, you will also need the up-to-date backup copy of your reference diskette and diagnostic diskette. WARNING: Do not open the static-protective bag containing the drive until instructed to do so. Static electricity can damage the drive. Hardware and software considerations Operating system ---------------- The operating system and hardware are two of the factors that determine the number of drives a computer can support. The manuals for your computer and operating system can help you to determine the number and type of hard disk drives you can use. Power supply ------------ Two factors that determine the number of internal drives that a computer or SCSI storage enclosure can support are: 1 The available current of the power supply 2 The nominal operating current of each drive installed Most computer power supplies have output over-current protection. If the total allowed current is exceeded, the power supply shuts down. The computer must be turned off and turned on again. SCSI ID Each SCSI device connected to a SCSI adapter must be assigned a unique SCSI identification number (ID). The ID you assign to this device depends on the number of SCSI devices connected to the SCSI adapter and the SCSI IDs already assigned to those devices. Note: All IBM SCSI controllers support SCSI IDs 6 through 0. (ID 7 is used for the SCSI controller.) Some SCSI controllers support SCSI IDs 15 through 8. If your SCSI controller supports more than seven devices, then you can use SCSI IDs 15 through 8. If you are not sure if your SCSI controller supports more than seven devices, refer to the documentation that came with your SCSI controller for information. If you have an IBM PS/2 computer, you can view your SCSI ID settings by accessing the system programs. From the main menu, select Set configuration. The select Set and view SCSI configuration. Other computers might have utility programs that enable you to view the SCSI configuration, or you might have to physically inspect the installed SCSI devices to see how the IDs are set. For more information, refer to the documentation that came with your computer or SCSI controller. Handling precautions -------------------- 1 Turn off all attached devices first; then turn off the computer. 2 Unplug all the power cords from electrical outlets before starting installation. 3 Disconnect all power cables from your computer and attached devices before starting installation. 4 Limit your movement. Movement can cause static electricity to build up around you. 5 Handle the drive carefully and by the edges. 6 Do not touch any exposed printed circuitry. 7 Prevent other people from touching the components or the drive. 8 When you are installing the drive, touch the static-protective package containing the drive to a metal expansion-slot screw or other unpainted metal surface on the computer, for at least 2 seconds. (This drains static electricity from the package and your body.) 9 When possible, remove the drive and install it directly into the computer without setting it down. If this is not possible, place the drive, component side up, on the static-protective bag on a flat surface until the drive is installed. 10 Do not place the drive on the computer cover or on a metal table. Installing the drive -------------------- These instructions guide you as you install the drive inside your computer or storage enclosure. Step 1. Setting the jumpers and terminators Note: Be sure you have chosen the SCSI ID before continuing. If you did not yet choose the SCSI ID, go to "SCSI IDs" above, then return here. Follow these steps to set the SCSI ID to match your chosen SCSI ID. 1 Touch the static-protective bag containing the drive to a metal expansionslot cover on the computer. This drains any static electricity from the package and your body. 2 Remove the drive from the static-protective bag, holding the drive by the edges. Do not touch any exposed components on the drive. 3 Place the drive on the bag, on a flat surface. 4 When the Auto Start feature is enabled, the hard disk drive motor starts as soon as the computer is turned on. Locate the Auto Start jumper by referring to the documentation that came with your drive. If the Auto Start jumper is not in place, the hard disk is started by a command from the SCSI controller. For drives installed in IBM computers or storage enclosures ensure that this jumper is off. The hard disk drive is started in a staggered sequence. This reduces the start-up load on the power supply. For non-IBM computer, refer to the documentation that came with your computer for further information. 5 Set the SCSI ID that you selected. To remove a jumper, pull it straight off. To install a jumper, line up the two holes in the jumper with the appropriate two pins on the drive. Then push the jumper onto the pins until it is completely seated and covers both pins. 6 Store any jumpers you do not use in a safe place, in case you need to change the SCSI ID for this drive later. WARNING: If you have extra jumpers, do not store them on any of the extra pins on the connector. Storing them on a set of pins could damage the drive. Step 2. Connecting the terminator The location of the drive you are installing inside the computer or storage enclosure determines whether you need to connect a terminator or put a jumper on the Enable Active Termination pins. Read the information in the following table to determine if you must install the terminator. For more information about termination, refer to the documentation that came with your computer. Note: A SCSI chain of devices consists of multiple SCSI devices connected by a SCSI cable to a SCSI controller. If the hard disk drive is: Then: The last physical device on a SCSI chain of Install the terminator devices inside the computer. The last physical device on a SCSI chain of Install the terminator devices inside an external storage enclosure. Step 3. Enabling term power If your drive has a jumper for term power and your SCSI controller is suppling term power, (check with the manufacturer of your controller) then you do not need to enable the term power. The jumper should be off. For help in locating the term power jumper, refer to the documentation that came with your drive. Step 4. Installing the drive For the specific information on installing a hard disk drive, refer to the documentation that came with your computer. You will be required to mount the drive inside your computer, and connect signal and power cables to the hard drive. When installed in an enclosure, the drive is attached by cable to the external connector of a SCSI controller. The controller can be either on a SCSI adapter or built into the system board inside of your computer. Note: Be sure to use the correct screws provided with your drive. Using the wrong ones might cause damage to the drive. Step 5. Completing the installation procedure The installation of the drive is complete. Reinstall the cover on the computer or storage enclosure. Store these instructions and any extra parts in a safe place in case you change your configuration. After installing your hard disk drive, use the information that came with your computer to reconfigure your system. When you power on your system, turn on all attached devices first; then turn on the computer. If you have any problems at this point, turn off all attached devices; then, turn off the computer and check that: 1 The cables are installed correctly 2 No options or cables are loose 3 The SCSI ID is properly set 4 No two SCSI drives have the same SCSI ID 5 The terminators are properly installed Turn on all attached devices; then, turn on the computer. If you still have a problem, refer to the troubleshooting information in the documentation that came with your computer. Step 6. Update configuration Whenever you add or remove an option from your computer, you must update the configuration information. Your computer might have an automatic configuration program, or you might have to follow a specific procedure. For more information, refer to the documentation that came with your computer. Step 7. Preparing the drive for use Having successfully installed the hard disk drive, you need to prepare it for use. Depending on the operating system you are using, you might need to partition then format the hard disk. Refer to the documentation that came with your operating system for information on how to format your new drive. To make the drive just installed your primary drive, you might need to create a new system partition on the drive. For information on creating a new system partition, refer to the documentation that came with your operating system. Troubleshooting --------------- You might be able to solve a problem yourself. Before calling IBM, you might want to try some or all of the following troubleshooting procedures. 1 Remove and reattach all drive cables 2 Remove and reseat the drive 3 Place the drive in a different slot, if one is available 4 If your drive contains jumpers or switches, check that they are set as specified 5 Reread any software instructions; be sure software settings are correct 6 Inspect the drive for damage, such as bent pins 7 Check the computer manual for instructions about the installation of upgrades. Look for a section about system setup or system configuration. Follow all procedures. 8 After completing these steps, reassemble the computer and connect the power cord. If you are still having problems and want to call IBM technical support, have available as much of the following information as possible: 1 Drive model or P/N and description 2 Computer manufacturer and model 3 Exact wording of error message (if any) 4 Description of the problem 5 Hardware and software configuration information for your system If possible, be at your computer. Your technical support rep might want to walk you through the problem during the call.
