  • Page 17: General Description

    Barracuda 9 Installation Guide, Rev. B General description Barracuda 9 SCSI disc drives are high-speed, random-access digital-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 20 A –10% tolerance is permissible during initial start of the spin- dle but must return to ±5% before reaching 7,200 RPM. The ±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initiator.
  • Page 21 Barracuda 9 Installation Guide, Rev. B No terminator power. See 11.7.3.4 in the Barracuda 9 Product Manual. All power-saving features are enabled; ASA II code only. Seeking is defined as a third-stroke seek at OD. The command is issued every 20 msec. Read track is defined as repeat reads of track 15 with a duty cycle of: 78% for N drives, 32% for W drives, 48% for WC drives, 44% for WD drives, and 44% for DC drives.

  • Page 22: Initial Setup Information

    Initial setup information The general information beginning on this page applies to all of the Barracuda 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 Barracuda 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 highest-num- bered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive.
  • Page 24 The top example in Figure 2 shows an internal hard disc at one end of the SCSI bus with the SCSI controller at the other end (both are terminated). The bottom example shows two additional SCSI devices connected externally—this means the SCSI con- troller is no longer on the end of the SCSI chain and should not be terminated.
  • Page 25 Barracuda 9 Installation Guide, Rev. B 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 26 Barracuda 9 Installation Guide, Rev. B Figure 3 shows two design approaches with one or more fans used to generate air flow. The air-flow patterns can be created by the fans either pushing or drawing air. The overall flow pattern can be directed from front to back, back to front, or side to side.

  • Page 27: Kühlung Des Systems

    Barracuda 9 Installation Guide, Rev. B Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf max- imal 50 C betragen. Die Produkthandbuch Barracuda 9 (Dokument 83329030) enthalten Anweisungen zur Beurteilung der Luftstromkonstruk- tion. Die Beurteilung muß sicherstellen, daß sich die Gehäuse- t e m p e r a t u r b e s t i m m t e r k r i t i s c h e r Ko m p o n e n t e n b e i Laufwerkbetrieb innerhalb zugelassener Grenzen hält.

To connect the DC power cable to the drive, simply insert the cable end into the drive’s DC power connector. Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an.
  • Page 32 Note. Signal ground on the power control board (PCB) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts.

Be sure that you understand this principle before formatting any hard disc drive.
