Ground means TTL logic low or logic ground. Disabling Spin-Up at Power On ----------------------------- A jumper in the 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. +---------+------+---------------------+ | 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 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.) +---------+------+---------------------+ | 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 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. The pins for all of the drives which are to be synchronized must be connected together. The drives must be of like model to operate. The spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%. 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 --------------------------- This drive provides on-board Alternative 2 active termination for the SCSI bus. The termination resistors, which are contained in two Single Inline Packs (SIPs) should be removed from the drive unless it is a SCSI device at the physical end of the bus. ********************************************************************** I N S T A L L ********************************************************************** CONNER CFP-1060D/1060E/1060S/1060W PRODUCT MANUAL REV.A 1/94 501064 Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). 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. Eight 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. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. The drive may be mounted in any orientation. Cabling the Drive CFP-1060D --------------------------- Connect the SCSI interface cable and the spindle synchronization cable (when needed). Cabling the Drive CFP-1060E --------------------------- The drive is intended for direct backplane connection to the SCA connector rather than through cabling. Attaching Power to the Drive CFP-1060E -------------------------------------- The drive is powered through the SCA connector and is intended for direct backplane connection rather than through cabling. SCSI Bus Cable CFP-1060S -------------------------- 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 0.1 meter (4 inches). - There should be 0.3 meters (12 inches) of cable between drives. - The total cable length should not exceed 6 meters (20 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. SCSI Bus Cable CFP-1060W ------------------------ 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 0.1 meter (4 inches). - There should be 0.3 meters (12 inches) of cable between drives. - The total cable length should not exceed 3 meters (10 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. Attaching Power to the Drive CFP-1060S/W ---------------------------------------- The drive has a 4-pin DC power connector, J4 mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins, part number 350078-4 or equivalent. Mixing Wide and Narrow SCSI Devices on a SCSI Bus ------------------------------------------------- It may sometimes be desirable to attach Narrow SCSI devices such as tape backup devices or CDROMs to the same SCSI Host Bus Adapter be- ing used to control Wide SCSI devices, such as the CFP-1060W. Intermixing of both Wide and Narrow SCSI devices on the same bus required special considerations: - The Narrow 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 spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%. Output Characteristics ---------------------- The output drivers for Data, Parity, REQ and ACK are optionally active negation. When they are set for active negation, they have three states: asserted, negated and high impedance. The remainder of the signals have open collector (drain) outputs. The drive maintain a high impedance state during power-on and power-off cycles. The driven signals have the following output characteristics when measured at the drive connector: Active Negation Driver Output Signal Characteristics Signal Characteristic | Value ----------------------------------+---------------------------- Signal Assertion | 0.1 VDC to 0.5 VDC at 48 mA Minimum Driver Output Capability | 48 mA (sinking) at 0.5 VDC Signal Negation | 2.0 VDC to 3.24 VDC at 7mA | 3.0 VDC at 20 mA Open Collector Driver Output Signal Characteristics Signal Characteristic | Value ----------------------------------+---------------------------- Signal Assertion | 0.0 VDC to 0.5 VDC at 45 mA Minimum Driver Output Capability | 48 mA (sinking) at 0.5 VDC Signal Negation | 2.5 VDC to 5.25 VDC Input Characteristics --------------------- Signal Characteristic | Value ----------------------------------+--------------------------- Signal Assertion | 0.0 VDC to 0.8 VDC Signal Negation | 2.0 VDC to 5.25 VDC Input Load (low level) | -20 A to 0.0 mA at 0.5 VDC Input Load (high level) | 0.0 mA to 20 A at 2.7 VDC External Terminator Power CFP-1060E ----------------------------------- The interface connector carries both power and ground so a separate TERMPWR interface line is not provided. Internal Termination CFP-1060E ------------------------------ This version of the drive has no on-board termination so the drive must be externally terminated. Alternative 2 active termination is recommended. Alternative 1 passive termination is not suitable for this application. Cable Requirements CFP-1060E ---------------------------- This version of the drive is designed to interface directly a mating connector which is on a passive back plane or directly into a motherboard. The same guidelines relative to impedance, stub length and distance between stubs apply for SCSI bus signal reliability. These guidelines may not be directly translated to a back plane design so these design rules are to eb viewed with respect to the intended purpose of controlling reflections and the propagation of signals down the bus. Since the characteristics for PCB signal traces are affected by trace width, proximity to ground, and trace routing, careful review of the back plane design and analysis of signal quality is highly recommended. Connector Requirements CFP-1060E -------------------------------- The drive's connector will mate with a AMP Champ 2-557103-2 vertical receptacle or the AMP Champ 2-557101-1 right angle receptacle. Single Connector Attachment (SCA) Signal Definitions ---------------------------------------------------- Power Four +12 Volt signals provide the +12 volt power to the drive. The current return for the +12 volt power is through the +12 Volt Ground signals. The maximum current that can be provided to the drive through the +12 Volt signal pins is 3 Amperes. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current is while the drive motor is starting. Three +5 Volt signal pins provide +5 volt power to the drive. The current return for the +5 volt power is through the +5 Volt Ground pins. It is expected that the +5 Volt Ground will also establish the digital logic ground for the drive. The maximum current that can be provided to the drive through the +5 Volt signal pins is 2 Amperes. The supply current and return current must be distributed as evenly as possible among the pins. Spindle Sync CFP-1060E ---------------------- The spindle rotation of up to 35 drives may be synchronized together by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 of each drive on connector J3. The spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%. LED Out CFP-1060E ----------------- The LED out signal is driven by the drive when the drive is perform- ing a SCSI operation. The LED out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +5 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. External Termination Power CFP-1060S ------------------------------------ Power to the on-board terminators is provided by the higher of the voltage supplied at Pin #26, J2 or the voltage level at the 5 Volt power input to the drive minus one diode drop. The diode prevents back flow of current to the drive. Termination Power to external terminators can be supplied by the drive through pin 26, J2. The TERMPWR line can be disconnected from the drive by removing Jumper E8. Internal Termination CFP-1060S ------------------------------ This drive provides on-board Alternative 2 active termination for the SCSI bus. The termination resistors, which are contained in two Single Inline Packs (SIPs) should be removed from the drive unless it is a SCSI device at a physical end of the bus. Cable Requirements CFP-1060S ---------------------------- A 50 conductor cable no more than 6 meters (19.68 feet) cumulative length with at least 28 AWG wire size and a characteristic impedance of 70 to 100 ohms (84 ohms nominal) is required. Connector Requirements CFP-1060S -------------------------------- The connector on the drive is a 50-position header which consists of 2 rows of 25 male pins on 0.100 inch centers. The mating connector is a SCSI-2 Non-shielded Alternative 1, A-cable connector. External Terminator Power CFP-1060W ----------------------------------- 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 1 diode drop. The diode prevents back flow of current to the drive. 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. Internal Termination CFP-1060W ------------------------------ This drive provides on-board Alternative 2 active termination for the SCSI bus. The termination resistors, which are contained in three Single Inline PAcks (Sips) should be removed from the drive unless it is a SCSI device at a physical end of the bus. Cable Requirements CFP-1060W ---------------------------- A 68 conductor cable no more than 3 meters (9.84 feet) cumulative length with at least 30 AWG wire size and a characteristic impedance of 70 to 100 ohms (84 ohms nominal) is required. Connector Requirements CFP-1060W -------------------------------- 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-1060D/1060E/1060S/1060W PRODUCT MANUAL REV.A 1/94 501064 Overview of the Drives ---------------------- The CFP1060 series are a family of high performance 3.5-inch low- profile (1.0 inch high) 1.06GB (formatted) disk drives. They all offer 9.0 millisecond average seek time for Reading, 9.5 millisecond seek time for Writing, with an average latency of only 5.55 ms. High capacity is achieved by utilizing a zone density recording technique using 9 recording zones at an areal density of 205 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 --------- +----------------------------------+--------+ | | 1060 | +----------------------------------+--------+ |Track-to-Track msec. typ. | 2 | +----------------------------------+--------+ |Average msec. read | 9 | | msec. write| 9.5 | +----------------------------------+--------+ |Full Track msec. | 16 | +----------------------------------+--------+ |Latency msec. avg. | 5.55 | +----------------------------------+--------+ Error Correction ---------------- The drive uses a three way interleaved 144-bit Reed-Solomon code to perform error correction and detection. For each 512-byte block, the on-the-fly error correction polynominal is capable of correcting: - one error burst of up to 22 bits in length - two error bursts each up to 11 bits in length ATTENTION!!! ============ The Adapter for the CFP-1060 80pin SCA Model to 50pin SCSI exist with or without BRAZED terminators! 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 5400 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. Head Positioning Mechanism -------------------------- The read/write heads are supported by a mechanism coupled to a rotary voice coil actuator. Buffer Management ----------------- The 512K byte buffer is treated by the queuing code as two 240KB buffers (F0H sectors) to maximize coalescing. Look ahead reads are performed by the drive when there are no commands in the queue awaiting execution. Sequential read or write commands are coalesced into single commands to the background processor. ********************************************************************** G E N E R A L ********************************************************************** SEAGATE SUPPORT SERVICES Seagate Technology ------------------ Technical Support Services If you need assistance installing your drive, consult your dealer.
