Barracuda 9FC Installation Guide, Rev. A 1 Preface This manual contains information for users of the Seagate ST19171FC (Fibre Channel interface) Barracuda disc drives. It provides technical support information, performance specifications, installation instructions, and a troubleshooting section. Additional information is available in the Barracuda 9FC Product Manual (part number 83329100). Contact your Seagate sales representative if you need to order this publication.
2 Barracuda 9FC Installation Guide, Rev. A 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. • 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 static electricity from the carrier or tray prior to inserting it into the system. Important safety information and precautions Caution.
Barracuda 9FC Installation Guide, Rev. A 3 Always observe the following warnings and precautions: • Perform all maintenance by following the procedures in this manual. • Follow all cautions and warnings in the procedures. • Use sound safety practices when operating or repairing the unit. • Use caution when troubleshooting a unit that has voltages present. Turn off power to the unit before servicing it.
4 Barracuda 9FC Installation Guide, Rev. A subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety-regulatory agency compliance in their end-use products and for certifying where required by law. A necessary part of meeting safety requirements is the provision for overcurrent protection on drive SELV supply voltages. This unit is a component part and as such is not meant to comply with FCC or similar national requirements as a stand-alone unit.
Barracuda 9FC Installation Guide, Rev. A 5 Die Warn- und Vorsichtshinweise sind nicht allumfassend! Es ist uns einfach nicht möglich, alle Wartungsmethoden oder die eventuellen Risiken jeder Methode zu kennen, zu beurteilen und Sie entsprechend zu beraten. Aus diesem Grund haben wir auf eine derartige umfassende Beurteilung verzichtet.
6 Barracuda 9FC Installation Guide, Rev. A • Nehmen Sie keine Platinen aus dem Laufwerkgehäuse. Wenn eine Platine defekt ist, muß das gesamte Laufwerk zur Reparatur eingeschickt werden. Die Herausnahme von Platinen durch anderePersonen als die für die werkseitige Reparatur zuständigen kann zu einer Beschädigung der Komponenten und Erlöschen des Garantieanspruchs führen.

Dieses Gerät ist eine Baugruppe und unterliegt als solche nicht den Anforderungen der FCC oder ähnlicher nationaler Behörden für eigenständige Geräte. Technische Testergebnisse zu elektromagnetische Strahlung sind für Designer von Untersystemen auf Anfrage von der Seagate-Sicherheitsabteilung erhältlich.

10 Barracuda 9FC Installation Guide, Rev. A General description Barracuda 9FC disc drives are high-speed, random-access digital-data storage devices designed to be used within a Fibre Channel host system. The drive is a component for installation in an enclosure designed for the drive. The disc drive must receive adequate cooling (refer to “Providing adequate cooling”) and it must be sufficiently grounded and shielded from emissions.

12 Barracuda 9FC Installation Guide, Rev. A Installing the ST19171FC drive To install a ST19171FC drive, simply plug the drive directly into your system’s Fibre Channel backpanel 40-pin single connector attachment (FC-SCA). There are no jumpers or terminators on the drive, and power is supplied through the connector. Table 1 on page 21 lists the pin descriptions of the 40-pin FC-SCA.
Barracuda 9FC Installation Guide, Rev. A 13 Figure 2 shows one design approach with one or more fans used to generate air flow. The air-flow pattern can be created by the fans either pushing or drawing air. The overall flow pattern must be directed from side to side in most FC-SCA systems. Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50oC betragen.

Barracuda 9FC Installation Guide, Rev. A 15 Mounting the drive Do not touch the connector pins or any components on the control board without observing staticdischarge precautions. Always handle the drive by the frame only. Mount the drive to the host system’s chassis using four 6-32 UNC screws. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. See Figure 3. The maximum length that the screws should extend into the chassis mounting holes is 0.

18 Barracuda 9FC Installation Guide, Rev. A Inserting the drive Most systems provide a way to insert the drive using a carrier or tray which allows the drive to be hot-plugged into the system’s Fibre Channel 40-pin single connector attachment (FC-SCA). Refer to your system documentation about the method they provide and follow their instructions. When installing the drive on a carrier or tray, discharge the static electricity from the carrier or tray prior to inserting it into the system.
Barracuda 9FC Installation Guide, Rev. A 19 Warning. Information can be lost if you enable write cache and there is a system failure (for example, power failure) before the data has actually been physically written to the disc. OEM drives are shipped with write cache disabled by default to enhance data integrity. If you want to enable the write cache, refer to your system’s drive controller and software utility documentation.
