    Cheetah 9 Installation Guide, Rev. B Preface This manual contains information for users of the Seagate® Cheetah 9 SCSI disc drives. It provides support services, perfor- mance specifications, and initial setup information. Additional information is available in the Cheetah 9 Product Manual (part number 83329170).

  • Page 4: Electrostatic Discharge Protection

    • Ground yourself to the drive whenever the drive electronics are or will be exposed. Connect yourself to ground with a wrist strap (Seagate part number 12263496). Connection may be made to any grounded metal assembly. As a general rule, remember that you and the drive electronics must all be grounded to avoid potentially damaging static discharges.

  • Page 17: General Description

    Cheetah 9 Installation Guide, Rev. B General description Cheetah 9 SCSI disc drives are high-speed, random-access dig- ital-data storage devices. The drive is a component for installation in an enclosure designed for the drive. This is often a rack within the system or an external enclosure designed to house one or more disc drives or other peripheral units.
  • Page 18 Table 1. Drive characteristics Characteristics of the various drives covered by this manual are given in the following tables. Interface type: Cylinders (user accessable): Disk rotation: Avg. latency: Seek time Average read (typical) Average write (typical) Internal transfer rate (variable with zone) Multi-segmented cache Also operates per SCSI-1/SCSI-2/SCSI-3 protocols.

  • Page 20 Table 2. DC power requirements (Amps) Voltage regulation Max. start current 3, 6, 9 Peak DC Delayed motor start 1, 4 (max) Peak operating current Typical DC Maximum (peak) Measured with an average reading DC ammeter. Instanta- neous +12V current peaks will exceed these values. A –10% tolerance is permissible during initial start of the spin- dle but must return to ±5% before reaching 10,000 RPM.
  • Page 21 Cheetah 9 Installation Guide, Rev. B At power-up, the motor current regulator limits the +12V cur- rent to an average value of less than value shown in table, although instantaneous peaks may exceed this value. These peaks should measure 5 msec duration or less. Minimum current loading for each supply voltage is not less than 4% of the maximum operating current shown.

  • Page 22: Initial Setup Information

    Initial setup information The general information beginning on this page applies to all of the Cheetah 9 drive models. After reading the general informa- tion topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
  • Page 23 Cheetah 9 Installation Guide, Rev. B SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system’s SCSI controller usually uses the ID that has the highest priority interrupt in the SCSI I/O system. This is always ID7.
  • Page 24 the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user’s manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Cheetah drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain.

SCSI bus termination Terminator power You usually will not need to change this option and can normally leave the drive configured as it was shipped from the factory. For information about how to change the terminator power option on your drive, refer to the appropriate drive-specific section.

  • Page 31 Cheetah 9 Installation Guide, Rev. B Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50 C. The drive’s product manual (83329170) describes how to evalu- ate the air-flow design. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation.
