Disabling Spin-Up at Power On ----------------------------- A jumper in the J7:E5 location, disables spin up after power-on for applications where spin up sequencing is necessary. Disabling spin up on application of power can also be enabled by setting the DSPN bit in MODE SELECT page 00H (Operating Parameters). The Host must issue a Start UNIT command to cause the drive to spin up. +---------+------+---------------------+ | J7:E5 | DSPN | Result | +---------+------+---------------------+ | IN | 0 | Spin Disabled | +---------+------+---------------------+ | IN | 1 | Spin Disabled | +---------+------+---------------------+ | OUT | 0 | Spin up on Power On | +---------+------+---------------------+ | OUT | 1 | Spin Disabled | +---------+------+---------------------+ Delaying Spin Up at Power On ---------------------------- A jumper in the J7:E6 location, delays spin up on power-up by the value of the drive's SCSI ID multiplied by 4 seconds (i.e. SCSI ID 4 will delay 16 seconds). Delaying spin up on application of power can also be enabled by setting the SDLY bit in MODE SELECT page 00H (Operating Parameters). +---------+------+---------------------+ | J7:E6 | SDLY | Result | +---------+------+---------------------+ | IN | 0 | Spin Delayed | +---------+------+---------------------+ | IN | 1 | Spin Delayed | +---------+------+---------------------+ | OUT | 0 | Spin up on Power On | +---------+------+---------------------+ | OUT | 1 | Spin Delayed | +---------+------+---------------------+ Disabling the SCSI Bus Parity ----------------------------- SCSI parity is always enabled in both directions, unless the J7:E7 Parity disable jumper is installed. Installing the jumper will cause the drive to ignore SCSI bus Parity In but it will continue to generate SCSI bus parity out. Disabling SCSI Bus Terminator Power (TERMPWR) --------------------------------------------- Power to the on-board terminators is provided by the higher of the voltage supplied at Pin #17, 18, 51 & 52, J2 or the voltage level at the 5 Volt power input to the drive minus one diode drop. Termination Power to external terminators can be supplied by the drive through Pin #17, 18, 51 & 52, J2. The TERMPWR line can be disconnected from the drive by removing Jumper E8. Jumper E8 | Result ----------+---------------------------------------------------- IN | TERMPWR (J2, Pin #17, 18, 51 & 52) connected to the | drive's internal termination power. ----------+---------------------------------------------------- OUT | TERMPWR (J2, Pin #17, 18, 51 & 52) open circuit. Using the J5 Auxiliary Connector -------------------------------- External logic cabled to the J5 connector may be used to control certain characteristics of the drive or access signals.

This signal has a value of 0 when it is negated and a value of 1 when it is asserted for the purpose of selection or arbitration. This signal is latched within 250 msec of the application of valid power to the drive or optionally the negation of -RST. If SCSI ID SEL0 is intended to be selected, the host must provide a low impedance connection from -SEL(0) to -XTFALT or to ground, while the ID is being latched, through an appropriate means. -XTFAULT This signal is intended to drive an LED to indicate and external fault condition has occurred. This signal is held asserted following the application of power or optionally the negation of -RST during initialization while the SCSI ID is being read. This signal is not supported but meets the requirements of negating the signal while the ID is being read. -SEL1 Bit 1 of the binary coded SCSI ID selection input. This signal has a value of 0 when it is negated and a value of 2 when it is asserted for the purpose of selection or arbitration. This signal is latched within 250 msec of the application of valid power to the drive or optionally the negation of -RST. If SCSI ID SEL1 is intended to be selected, the host must provide a low impedance connection from -SEL1 to -VUNIQ or to ground, while the ID is being latched, through an appropriate means. -VUNIQ This signal is an open-collector output available for Vendor Unique usage. This signal is not supported but meets the requirement of negating the signal while the ID is being read. -SEL2 Bit 2 of the binary coded SCSI ID selection input. This signal has a value of 0 when it is negated and a value of 4 when it is asserted for the purpose of selection or arbitration. This signal is latched within 250 msec of the application of valid power to the drive or optionally the negation of -RST. If SCSI ID SEL2 is intended to be selected, the host must provide a low impedance connection from -SEL2 to -SPSYNC or to ground, while the ID is being latched, through an appropriate means. -SPSYNC This signal used to provide a spindle rotation synchronization re- ference. This drive does not support spindle synchronization. This signal meets the requirement of negating the signal while the ID is being read. -SEL3 Bit 3 of the binary coded SCSI ID selection input. This signal has a value of 0 when it is negated and a value of 8 when it is asserted for the purpose of selection or arbitration. This signal is latched within 250 msec of the application of valid power to the drive or optionally the negation of -RST. If SCSI ID SEL3 is intended to be selected, the host must provide a low impedance connection from -SEL3 to -XTACTV or to ground, while the ID is being latched, through an appropriate means. -XTACTV This signal is an open collector output intended to drive an LED to indicate the device is active. This signal is negated while the SCSI ID is being read. -GROUND This signal is connected to the drive's logic ground. +5 Volts This signal provides 5 volts of DC power to drive LEDs and is current limited by a 120 ohm resistor. -FAULT The assertion of this signal will cause the drive to stop any media- altering activity, which may result in the drive asserting -XTFALT or -VUNIQ, or both. This signal is intended to be used as a power failure warning and/or as a write protect input. This signal is not supported by this drive. Setting the Bus Termination --------------------------- All SCSI bus signals are common among all devices connected to the bus. All signal lines must be terminated at both ends of the bus with a terminator. The termination points define the end of the bus. This drive does not provide internal termination capability. ********************************************************************** I N S T A L L ********************************************************************** CONNER CFP-4207WD PRODUCT MANUAL REV.A 501-084, 06/95 Notes on Installation ===================== Mounting the Drive ------------------ The drive is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives will tolerate. The design features which allow greater shock tolerance are the use of rugged heads and media, a dedicated landing zone, closed loop servo positioning and specially designed motor and actuator assemblies. Six side, or four bottom base mounting points are provided to the customer. The drive is mounted using 6-32 UNC -2B X 0.16 maximum insertion length screws. Attaching Power to the Drive ---------------------------- The drive has a 4-pin DC power connector, J4 which is part of the Unified Connector, mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins, part number 350078-4 or equivalent. SCSI Bus Cable -------------- The cable should meet the following guidelines, particulary with FAST SCSI-2 systems: - Do not route the data cable next to the drive PCB or any other high frequency or large current switching signals. Improper drive opera- tion can result from improper cable routing. - Cable stubs should not exceed 0.2 meter (8 inches). - There should be 0.3 meters (12 inches) of cable between drives. - The total cable length should not exceed 25 meters (82 feet) and may have to be reduced if a mixture of round and flat cable are used. - Do not tightly bundle excess flat cable against each other since this promotes cross coupling of signals on the cable. Use spacers to maintain a minimum of 0.050 inches (1.27mm) gap between cable runs. - Do not clamp the cable tightly against a metal chassis since this will degrade the signal. Use spacers or a non-flammable insulation material to maintain a gap between the chassis and the cable. Mixing Wide and Narrow SCSI Devices on a SCSI Bus ------------------------------------------------- It may sometimes be desirable to attach Narrow Differential SCSI devices such as tape backup devices or CDROMs to the same SCSI Host Bus Adapter being used to control Wide Differential SCSI devices. Intermixing of both Wide and Narrow Differential SCSI devices on the same bus required special considerations: - The Narrow Differential SCSI devices must be placed at the physical end of the bus. - The high byte of the SCSI data bus must be terminated at the transition adapter from the 34-pair wire to the 25-pair wire. - The cable impedance of the 34-pair wire and the 25-pair wire should be as closely matched as possible. - The 68-pair cable with 30 AWG wire uses four wires to carry TERMPWR, which must be joined to wire 26 of the 25-pair wire, if terminator power has to be carried over the cable.

The driven signals have the following output characteristics when measured at the drive connector. Signal Characteristic | Value ----------------------------------+---------------------------- High Level Output Current (IOH) | -60mA, maximum Low Level Output Current (IOL) | 60mA, maximum Differential Output Voltage (VODH)| 1.0 volt, minimum Differential Output Voltage (VODL)| -1.0 volt, minimum High Level Output Voltage (VOH) | 3.0 volt, typical Low Level Output Voltage (VOL) | 1 volt, typical Input Characteristics --------------------- The input characteristics of the drive meets or exceeds the requirements of EIA RS-485 (ISO 8482-1982, TIA TR30.2). The characteristics of the input receivers and the requirements for each signal received by the drive as measured at the drive connector are shon in the following table. Signal Characteristic | Value ----------------------------------+---------------------------- Maximum input capacitance | <25pF Input hysteresis | 45 millivolt, typical Termination ----------- All SCSI bus signals are common among all devices conected to the bus and the signal lines must be terminated at both ends of the bus with a terminator. The termination points define the end of the bus. This drive does not provide internal termination capability. External Terminator Power ------------------------- Termination Power to external terminators can be supplied by the drive through Pin #17, 18, 51, & 52, J2. The TERMPWR line can be disconnected from the drive by removing Jumper E8. The following table describes the electrical characteristics of the TERMPWR line when it is used to supply power to an external terminator. TERMPWR Electrical Output Characteristics Signal Characteristic | Value ----------------------------------+------------------------------- Supply voltage | 4.06 VDC to 4.56 VDC | (dependent on power supplied to | the drive) Minimum source capability | 1000 mA Internal Termination -------------------- The CP4207WD does not provide on-board termination. External Termination -------------------- All assigned signals (except TERMPWR, RESERVED and GROUND) must be terminated at each ed of the bus with a terminator network. The Resistor tolerances in the terminator network must be 5% or less. The characteristic impedance of differential terminators is 122 ohms. Cable Requirements ------------------ A 68 conductor cable no more than 25 meters (82 feet) cumulative length with at least 30 AWG wire size and a characteristic impedance of 115 to 160 ohms (122 ohms nominal) is required. The cable should also meet the followig additional requirements: Interface Cable Electrical Characteristics Specification |Value -----------------------------------+------------------------------- Signal Attenuation |0.095dB max. per meter at 5MHz Maximum Propagation Delay |5.4 ns Pair-toPair Propagation Delay Delta|0.15 ns max. per meter Pair-to-Pair Diff. Impedance Delta |20 ohms DC Resistance |0.230 ohms max. per meter at 20*C Stubs on the cable should not exceed 0.2 meters, where a stub is defined as the conductor length from the transceiver to the mainline SCSI cable. Stubs should be spaced at least 0.3 meters apart and stup clustering should be avoided. Connector Requirements ---------------------- The connector on the drive is a 68-pin. The mating connector is a SCSI 3 Non-shielded P-cable connector. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CFP-4207WD PRODUCT MANUAL JUNE 1995 REV. A 501-084 Overview of the Drives ---------------------- The CFP4207 series is a family of high performance 3.5-inch 4.2GB (formatted) disk drives. They all offer 9 millisecond average seek time for Reading, 9.5 millisecond seek time for Writing, with an average latency of only 4.17ms. High capacity is achieved by utilizing a zone density recording technique using 15 recording zones at an areal density of 317 Mbits per square inch. These drives feature high performance while maintaining low power consumption to reduce power supply current and system cooling requirements in disk arrays. They are designed to operate on the Small Computer System Interface (SCSI) and are SCSI-2/3 command compatible. The mechanical and major electronic components are identical between the models and differ only in the host interface implementation. Firmware -------- The drive's firmware can be considered in two parts. The first part principally reside in the ROM for the 68HC16 background processor. This processor is responsible for: - starting the spindle motor and maintaining precise rotational speed - controlling track following and actuator motion during seeking - managing background R/W activity - power management - monitoring the overall health of the drive. The interface processor's control microcode resides in both ROM and RAM. The RAM portion of the microcode can be upgraded in the field with using software. The interface processor firmware functions include: - reporting drive status and error conditions to the host - manage operating parameters for the drive - parsing the Command Descriptor Block and checking for illegal fields - converting the LBA to CHS and initiating read and write operations to the background processor - defect management - serial port communications Since parsing/decoding of commands and execution of the Read/Write functions are handled by separate processors, command execution can be overlapped in multiple initiator or Tagged Command Queuing environments. Functions such as seek re-ordering and command coalesc- ing can also be overlapped when the drive is operating with a host environment capable of supporting Tagged Command Queuing. Seek Time --------- +----------------------------------+--------+ | | 4207 | +----------------------------------+--------+ |Track-to-Track msec. typ. | 2 | +----------------------------------+--------+ |Average msec. read | 9.0 | | msec. write| 9.5 | +----------------------------------+--------+ |Full Track msec. | 18 | +----------------------------------+--------+ |Latency msec. avg. | 4.17 | +----------------------------------+--------+ Error Correction ---------------- The drive uses a three way interleaved 96-bit Reed-Solomon code to perform error correction. An additional 48-bit Cyclic Redundancy Code (CRC) provides additional miscorrection detection. For each 512-byte block, the on-the-fly error correction polynominal is capable of correcting: - one error burst of up to 41 bits in length - two error bursts each up to 17 bits in length The miscorrection probability is less than 1 bit in 10(24) bits transfered. Read/Write Heads and Disks -------------------------- Data is recorded on 95mm diameter disks trough 3370-type 50% nano- slider thin film heads with transverse pressure contour (TPC) air bearing surfaces. The TPC air bearing surface allows the head to fly at a uniform height regardless of radial position. This improves data reliability and allows the serial density to be more uniform with radius. The CFP4207 series contains the sputterd thin film disks with twenty data surfaces and twenty read/write heads. At power-down, the heads are automatically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is inside the data tracks. Head Positioning System ----------------------- The read/write heads are supported by a mechanism coupled to a rotary voice coil actuator. Drive Motor and Spindle ----------------------- A brushless DC direct-drive motor assembly is mounted on the drive's base. The motor rotates the drive's spindle at 7200 RPM. The motor/ spindle assembly is dynamically balanced to provide minimal mechanical runout to the disks. A dynamic brake is used to provide a fast stop to the spindle motor and return the heads to the landing zone when power is removed. Safety Standards ---------------- The drive is designed to comply with relevant product safety standards, including: - UL 478, 5th edition, Standard for Safety of Information Processing and Business Equipment - UL 1950, Standard for Safety of Information Technology Equipment - CSA 22.2#220, Information Processing and Business Equipment - CSA 22.2#950, Safety of Electrically Energized Office Machines - IEC 380, Safety of Electrically Energized Office Machines - IEC 950, Safety of Information Technology Equipment Including Electrical Business Equipment - VDE 0805, VDE 0805 TIEL 100, VDE 0806 - Complies with FCC Class B, Part 15, Subpart J
