 When jumpered, the corresponding bit is a 1.

 Through the SCSI bus supports connection of up to seven devices,
 communication can occur only between two SCSI devices at a time. Each
 device has an assigned ID bit; that bit establishes device priority
 on the SCSI bus.

 When two SCSI devices communicate, one acts initiator and the other
 as a traget. The initiator originates an operation and the target
 performs the operation specified by the initiator. An initiator can
 address up to seven other logical units (LUNs) attached to one
 target. The drive has only one logical unit attached (LUN=0).

   |                 |
   +-----------------+

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


 Recommended Mounting Configuration
 ----------------------------------
 The drive may be mounted in any attitude using 6-32 screws with 1/8"
 maximum penetration. Allow adequate ventilation to the drive to
 ensure reliable operation over the operating temperature range.


 Host Equipment
 --------------
 Maxtor builds hard disk drives to meet the highest quality standards.
 Like all system peripherals, they depend on host equipment for
 adequate power and environment to realize their full performance
 potential and to operate in compliance wit applicable industry and
 governmental regulations. Give special attention to: power
 distribution, shielding, audible noise control, temperature
 regulation, and electro-static discharge.


 Interface Termination
 ---------------------
 SCSI devices require proper interface termination. On a SCSI bus
 daisy chain, terminate only the first and last device. All devices
 between the first and last devices must have their terminators
 removed. As shipped, the interface signal lines are terminated with
 two removable 220/330 ohm resistor network packs.

 A dot on the terminator (RP601-RP602) indicates the position of pin
 1; pin 1 is also identified as the terminator pin farthest from power
 connector. For the drive to function correctly, orient each
 terminator pack with its identifying pin 1 dot facing the direction
 opposite the power connector.

 Any device driving the disk inputs should be of the open collector
 type, capable of sinking at least 48 mA at a voltage level less than
 0.5 V DC (7438 or equivalent).

 Devices receiving Cheyenne Series disk drive outputs should be
 SCHMITT trigger type (74LS14, 74LS240, or equivalent) to improve
 noise immunity. The initiator should not load the bus with more than
 one standard low-power Schotky transistor-transistor logic (LSTTL)
 input load per line. The initiator should terminate all signals with
 220/330 ohm terminators.


 Buffering Scheme
 ----------------
 The drive has a 64K (7120S or 7060S) or 32K (7080S or 7040S) First-
 In-First-Out (FIFO) buffer. The buffer controller allows simultaneous
 transfer either:

  1.) to the drive from the initiator, or
  2.) from the drive to the initiator.


 32K or 64K Data Buffer and Look-Ahead Cache
 -------------------------------------------
 The target device anticipates sequential reads by placing all data on
 an accessed track into the data buffer, making that data immediately
 available to new READ commands. By temporarily placing small amounts
 of data in high-speed memory, cache with look-ahead read decreases
 access time to sequential data in the drive.

 Neither head switching nor seeking occur during look-ahead
 operations. Cache may hold the size of one physical track; from 1 to
 42 sectors (7120S or 7060S) or 1 to 36 sectors (7080S or 7040S).


 Power Connector
 ---------------
 Power is applied through either:

 J2, a 3-pin Molex connector (recommended mating connector; Molex
 PN 39-01-0033).

 OR

 4-pin AMP connector (recommended mating connector: AMP PN 1-480424-0,
 using AMP pins PN 350078-4). This power connector conforms to the
 industry-standard 4-pin power connector and provides proper mating
 with the 3-pin on-board Molex connector.


 Electrical Interface
 --------------------
 SCSI uses single-ended drivers and receivers which allow a maximum
 cable length of 18 feet (5.48 meters) from the first to the last
 device (up to 7 devices) on the bus. The drive interfaces to the
 SCSI host via a 50-pin keyed ribbon cable; Maxtor recommends the 3M
 PN 3425-3000 cable connector.

 All assigned signals are terminated with 220 ohms to +5 volts and
 330 ohms to ground at each end of the cable. SCSI requires removal of
 the two terminator networks on the drive when the drive is between
 terminated devices on a SCSI daisy chain. Terminators are fragile and
 must be removed carefully. Save them for later use.

 All signals driven by the drive are open collector and have the
 output characteristics as follows.

 Signal True                       0.0 V DC to 0.8 V DC
 Maximum Total Input Load          -0.4 mA @ 0.4 V DC
 Signal False                      2.5 to 5.25 V DC
 Minimum Input Hyteresis           0.2 V DC


 Air Filtration System
 ---------------------
 All Cheyenne Series drives are designed to operate in a typical
 office environment with minimal environmental control. Over the life
 of the drive, a 0.3 micron filter and breather filter (located within
 the HDA) maintain a clean environment to the heads and disks.


 Read/Write Electronics
 ----------------------
 An integrated circuit mounted within the sealed enclosure (near the
 read/write heads) provides one of four head selection (depending on
 the model), read preamplification, and write drive circuitry.


 Read/Write Heads and Disks
 --------------------------
 Two or four, low-mass, low-force minicomposite metal-in-GAP (MIG)
 read/write heads record data on the 3.5" diameter disk(s). Maxtor
 uses a sputterred thin-film media on all disks for Cheyenne Series
 drives.


 Voice Coil Actuator
 -------------------
 Cheyenne Series drives employ a rotary voice coil actuator which
 consists of a moving coil, an E-block or actuator arm assembly, and
 stationary magnets.

 The actuator moves on a low-mass, low-friction center shaft. The low
 friction generated contributes to fast average access time and low
 power consumption.


 Automatic Headpark and Lock
 ---------------------------
 Immediately following power-down, dynamic braking of the spinning
 disks delays momentarily and lets the heads move to an inner
 mechanical stop. A small fixed magnet holds the heads in place as the
 disk spin down. The heads release only upon reapplication of power.


 Acoustic Noise
 --------------
 Measurements made in idle (spinning) on-track mode.

      1 meter perpendicular to top cover   39 dBA (typical)
      Sound power (per ISO/DIS 7779        4.9 bel (typical)


 Magnetic Field
 --------------
 The externally induced magnetic flux density may not exceed 6 gauss
 as measured at the disk surface.

 Multi-Initiator Support
 -----------------------
 The drive provides full multi-initiator support with command queuing
 for up to seven initiators. The target device can accept up to six
 commands (one from each remaining initiator) while processing a
 command from a seventh initiator.


 How Look-Ahead Cache Functions
 ------------------------------
 In the absense of an error, corrected data, or an interrupt command,
 the drive caches not only requested sectors, but "look ahead" and
 caches data from the sector that follow. (Look-ahead cache reads
 across track boundaries.) The look-ahead feature prepares the drive
 to transfer cahed data when the host request it, and so prevents
 access time delays.


 Drive Meachanism
 ----------------
 A brushless DC direct-drive motor ratates the spindle at 3,525 RPM
 (7120S and 7060S) or 3,703 RPM (7080S and 7040S). The RPM specified
 are  0.1%.

 The dynamically balanced motor/spindle assembly ensures minimal
 mechanical runout of the disk(s). A dynamic brake provides a fast
 stop to the spindle motor upon power removal. The speed tolerance
 includes motor performance and motor circuit tolerances.


 Defect Management
 -----------------
 REASSIGN commands push data down within the cylinder to maintain
 sequential order and assure maximum performance. Format and geometry
 parameters are user-configurable to allow customization.

 The 7120S has 4 spare sectors per cylinder; the 7060S has 2. The
 7080S has 2 spare sectors of cylinder; the 7040S  has 1. These spare
 sectors are located at the end of each cylinder.


 Data Encoder/Decoder
 --------------------
 The data encoder/decoder, a single semi-custom integrated circuit,
 employs an RLL encoding scheme and provides all clocking necessary
 for synchronization. This circuit interfaces to the data sequencer
 and either encodes or decodes serial data to or from the HDA.


 Power-Up Sequence
 -----------------
 DC power (+5V and +12V) may be supplied in any order. Both power
 supplies must be present and within the tolerances of the power
 sensing circuit before the spin motor will operate. Once power is
 applied, the actuator lock automatically disengages. The drive then
 performs a recalibration sequence to track zero, spins up, and
 becomes ready in 10 sceonds. The drive executes its recalibration
 sequence whenever power is applied or the SCSI START/STOP command
 is invoked via the SCSI bus.


 Regulatory Compliance
 ---------------------
 Maxtor Cheyenne Series drives comply with relevant product safety
 standards such as UL, CSA, and TUV rules and regulations. As
 delivered, Cheyenne Series drives are designed for integration before
 use. They are Class B computing devices built in compliance with FCC
 rules and regulations, Part 15, Subpart J, governing the EMI of
 computing devices. Canadian Emissions Statement: This digital
 apparatus does not exceed the Class B limits for radio noise
 emissions from digital apparatus as set out in the radio interference
 regulations of the Canadian department of communicaions.
