By default, Quantum configures the drive with a SCSI ID of six; that is, with jumpers installed across the pins labeled A2 and A1, and no jumper installed across the pins labeled A0 and A3.

SCSI Bus Termination Power Jumper (TE) -------------------------------------- The TE jumper enables SCSI bus active termination on the drive when installed (TE=1). Only the two SCSI peripherals located at the end of the SCSI bus should have termination enabled. When TE is removed, the termination circuit is disabled. In the disabled mode, each individual SCSI bus line is electrically isolated from the termination source. The method allows easier enable and disable termination. SCSI Bus Termination Power Jumper (TP) -------------------------------------- The TP jumper enables the active termination circuit to receive power from an external host when installed (TP=1). A diode on the OCB allows the termination circuit to receive power either from the on-board +5V supply or from the external host. Wait/Spin Jumper (WAIT_SPIN) ---------------------------- With the Wait_Spin feature disabled (jumper not installed), at a power on or reset, the drive motor starts to spin automatically, and the drive prepares itself to perform read or write operations without the need for a start command. At a power on or reset, with the Wait_ spin jumper enabled, the host must send a START/STOP UNIT command to activate the drive motor for read or write operations. At the factory, Quantum configures the Viking hard disk drive with the Wait_Spin jumper disabled; that is, without a jumper installed across the Wait_Spin pins. Spin Delay Jumper ----------------- In addition, with the Spin Delay jumper enabled, the drive performs power sequencing to prevent an overload of the host's power supply due to simultaneous, peak start-up current demands from multiple devices. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM VIKING PRODUCT MANUAL 81-113146-01 14/11/96 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Orientation ----------- The mounting holes on the Viking hard disk drive allow the drive to be mounted in any orientation. Clearance --------- The printed-circuit board assembly (PCBA) is very close to the mounting holes. Clearance from the drive to any other surface - except mounting surfaces - must be 1.25 millimeters (0.05 inches) minimum. The specified screw length allows full use of the mounting- hole threads, while avoiding damaging or placing unwanted stress on the PCB. Ventilation ----------- The Viking hard disk drives operates without a cooling fan, provided the ambient air temperature does not exceed 131*F (55*C).

A key slot on the header prevents the incorrect installation of the header connector on the SCSI cable. To prevent the header connector on the SCSI cable from being plugged in backwards, use only a keyed header connector. Recommended header connectors and their part numbers: 50-pin connector (base part) AMP P/N 1-746195-2, or equivalent 50-pin connector strain relief AMP P/N 1-499508-2 or equivalent J1 SCSI Interface Connector 68-PIN ---------------------------------- The 68-pin connector is an AMP AMPLIMITE .050 Series III Cable Plug connector, 68-position (AMP P/N 749925-5. J1 Interface Connector 80-PIN ----------------------------- For board-to-board connections, use AMP CHAMP .050 Series I right-angle receptacle, 80-position (AMP P/N 5-175474-9) or Vertical Receptacle, 80-position (AMP P/N 5-175475-9). J1 12-pin Auxiliary Connector (68-Pin Connector) ------------------------------------------------ J1 on the 68-pin SCSI PCB contains a 12-pin auxiliary connector. The pin assignments for this connector are shown in the following table. Pin 1 SCSI Addr - A0 2 XTFAULT 3 SCSI Addr - A1 4 GND 5 SCSI Addr - A2 6 GND 7 SCSI Addr - A3 8 LED Cathode 9 TE 10 GND 11 LED Pwr (+5V) 12 NC Automatic Actuator Lock ----------------------- To ensure data integrity and prevent damage during shipment, the Viking uses a dedicated landing zone and Quantum's patented AIRLOCK. The AIRLOCK holds the headstack in the landing zone whenever the disks are not rotating. It consists of an air vane mounted near the perimeter of the disk stack and a locking arm that restrains the actuator arm assembly. When DC power is applied to the motor and the disk stack rotates, the rotation generates an airflow on the surface of the disk. As the flow of air across the air vane increases with disk rotation, the locking arm pivots away from the actuator arm, enabling the headstack to move out of the landing. When DC power is removed from the motor, an electric return mechanism automatically pulls the actuator into the landing zone, where the AIRLOCK holds it in place. Air Filtration -------------- Viking hard disk drives are Winchster-type drives. The heads fly very close to the media surface, at a nominal flying height of 0.3 microinches. Therefore, it is essential that the air circulating within the drive be kept free of paticles. Quantum assembles the drive in a Class-100, purified air environment, sealing the drive mechanism under a metal cover. When the drive is in use, the rotation of the disks forces the air inside the drive through an internal filter. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM VIKING PRODUCT MANUAL 81-113146-01 14/11/96 Product Overview ---------------- Quantum Viking hard disk drives are part of a family of high- performance, 1.0-inch-high, hard disk drives manufactured to meet the highest product quality standards. Viking hard disk drives use nonremovable, 3 -inch hard disks. Viking hard disk drives feature an embedded SCSI drive controller and use SCSI commands to optimize system performance. The drive manages media defects and error recovery internally, so these operations are transparent to the user. Formatted Capacity ------------------ At the factory, the Viking 2.28/4.56S receives a low-level format that creates the actual tracks and sectors on the drive. Reliability ----------- Mean Time Between Failures (MTBF): 800,000 Power On Hours (POH), typical usage Preventive Maintenance (PM): None Start/Stop: 40,000 cycles (minimum) Defect Management ----------------- The Viking drive allocates one sector per cylinder as a spare. In the factory, the media is scanned for defects. If a sector on a cylinder is found to be defective, the address of the sector is added to the drive's defect list. Sectors located physically subsequent to the defective sector are assigned logical block addresses such that a sequential ordering of logical blocks maintained. This inline sparing technique is employed in an attempt to eliminate slow data transfer that would result from a single defective sector on a cylinder. If more than four sector is found defective on a cylinder, the inline sparing technique is applied only to the first sector. The remaining defective sectors are replaced with the nearest available spare sectors on nearby cylinders. Such an assignment of additional replacement sectors from nearby sectors rather than having a central pool of spare sectors is an attempt to minimize the motion of the actuator and head that otherwise would be needed to find a replace- ment sector. The result is minimal reduction of data throughput. Seek Times ---------- +-----------------------+-----------+ |Times | Typical | |msec. | Nominal | +-----------------------+-----------+ |Single Track Seek | 1.0 | +-----------------------+-----------+ |Average Seek (Read) | 8.0 | +-----------------------+-----------+ |Average Seek (Write) | 10.0 | +-----------------------+-----------+ |Full-Stroke Seek | 18 | +-----------------------+-----------+ Error Correction Control ECC ---------------------------- The Viking 2.28/4.56 ECC system uses a 28-byte ECC pattern, including four six-byte Reed-Solomon interleaves and four cross-check bytes. All read data is subject to ECC-on-the-fly correction. Both single- and double-burst errors will be corrected on-the-fly in firmware with hardware support. Triple-burst error correction is performed, if required, after an attempt has been made to re-read the data. Disk Caching ------------ The Viking hard disk drive incorporates DisCache, a 256K disk cache, to enhance drive performance. This integrated feature is user- programmable and can significantly improve system throughput. Read and write caching can be enabled or disabled by using the MODE SELECT command.
