Barracuda 18 Installation Guide, Rev. C 1 Preface This manual contains information for users of the Seagate® Barracuda 18 SCSI disc drives. It provides support services, performance specifications, and initial setup information. Additional information is available in the Barracuda 18 Product Manual (part number 77767512). Contact your Seagate sales representative if you need to order this publication. Electrostatic discharge protection Caution.
2 Barracuda 18 Installation Guide, Rev. C • Turn off the power before removing or installing the DC power cable. • Do not remove any circuit boards from the drive. • Never use an ohmmeter on any circuit boards. • When installing the drive on a carrier or tray, discharge the carrier or tray prior to inserting it into the system. Important safety information and precautions Caution. Use forced-air ventilation when bench-testing the drive to ensure proper cooling of drive components.
Barracuda 18 Installation Guide, Rev. C 3 • Follow the precautions listed above in “Electrostatic discharge protection.” • Do not remove any circuit boards from the drive. Return the entire drive for depot repair if any circuit board is defective. Removal of circuit boards by personnel not performing depot repair will damage components and may void the warranty. • Do not remove the head and disc assembly (HDA) from the drive. Return the entire drive for depot repair if the HDA is defective.

Barracuda 18 Installation Guide, Rev. C 7 Regulatory agency compliance Electromagnetic susceptibility As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of those integrating the drive within their systems to perform those tests required and design their system to ensure that equipment operating in the same system as the drive or external to the system does not adversely affect the performance of the drive.

Barracuda 18 Installation Guide, Rev. C 15 General description Barracuda 18 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.

Barracuda 18 Installation Guide, Rev. C 21 Initial setup information The general information beginning on this page applies to all of the Barracuda 18 drive models. After reading the general information topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
22 Barracuda 18 Installation Guide, Rev. C 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. ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority in a 16-bit I/O system. The lower priority SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive. Note.
Barracuda 18 Installation Guide, Rev. C 23 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 Barracuda drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain.

30 Barracuda 18 Installation Guide, Rev. C Note. This drive model plugs directly into a backplane connector and therefore uses no cables. Figure 3e.
Barracuda 18 Installation Guide, Rev. C 31 Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient air temperature around the drive should not exceed 50°C. However, to achieve maximum reliability, the ambient temperature should be about 15°C below this value most of the time. The drive’s product manual (77767512) describes how to evaluate the air-flow design.
32 Barracuda 18 Installation Guide, Rev. C Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50°C betragen. Die Produkthandbuch Barracuda 18 (Dokument 77767512) enthalten Anweisungen zur Beurteilung der Luftstromkonstruktion.

34 Barracuda 18 Installation Guide, Rev. C Mounting the drive and connecting cables Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. 1. Mount the drive to the host system’s chassis using four 6-32 UNC screws.
Barracuda 18 Installation Guide, Rev. C 35 1. Befestigen Sie das Laufwerk mit vier 6-32-UNC-Schrauben am Gehäuse des Host-Systems. Die beiden Seiten des Laufwerkes sind mit jeweils zwei Befestigungslöchern versehen, die Unterseite des Laufwerkes weist vier weitere Befestigungslöcher auf. Gemessen von der Außenfläche des Gehäuses dürfen die Schrauben maximal 3,81 mm in die Befestigungslöcher des Gehüuses hineinragen. Die Schrauben müssen gleichmäßig, jedoch nicht zu fest, angezogen werden.

Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an. Das Kabel darf nicht gedehnt oder gedrückt werden und es darf den Luftstrom zur Kühlung des Systems nicht behindern. Das Laufwerk wird über einen 4-poligen, neben dem SCSIAnschluß befestigten Steckverbinder mit Gleichstrom versorgt.
Barracuda 18 Installation Guide, Rev. C 37 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. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions.

40 Barracuda 18 Installation Guide, Rev. C Formatting the drive Warning. Formatting a drive erases all user data. Be sure that you understand this principle before formatting any hard disc drive. It is not necessary to format a drive that previously has been used to store data, unless your intention is to erase all user data. Note. Seagate is not responsible for lost user data. 1. 2. 3. Turn on DC power.

42 Barracuda 18 Installation Guide, Rev. C N drives Terminating the drive “N” model drives are terminated with permanently mounted IC active terminators. If you install one of these drives and it is not on the end of the SCSI bus, disable the terminators by removing the jumper “TE” from pins 15 and 16 of connector J2 (see Figure 8). If you install the drive on the end of the SCSI bus, enable termination by installing a jumper on pins 15 and 16 of connector J2.
Barracuda 18 Installation Guide, Rev. C 43 N drives Terminator power There are four possible terminator power (TP) configurations for “N” model drives (see Figure 9).
