Barracuda 9 Installation Guide, Rev. A 11 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.

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. 3 See the +12V current profile in the Barracuda 9 Product Manual (publication number 83329030).
Barracuda 9 Installation Guide, Rev. A 15 11 No terminator power. See 11.7.3.4 in the Barracuda 9 Product Manual. 12 All power-saving features are enabled; ASA II code only. 13 Seeking is defined as a third-stroke seek at OD. The command is issued every 20 msec. 14 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.
16 Barracuda 9 Installation Guide, Rev. A Initial setup information The general information beginning on this page applies to all of the Barracuda 9 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.
Barracuda 9 Installation Guide, Rev. A 17 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-numbered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive. Note. Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2).
18 Barracuda 9 Installation Guide, Rev. A 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 controller is no longer on the end of the SCSI chain and should not be terminated. Note. Some controllers prefer to remain terminated even if they are in the middle of the chain.
Barracuda 9 Installation Guide, Rev. A 19 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. I/O circuits and data path widths • WD and DC models use differential I/O circuits. You cannot mix these models with single-ended models (N, W, WC) on the same SCSI bus.
20 Barracuda 9 Installation Guide, Rev. A traveled by air that is heated by the drive and by other nearby heat sources. 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.
Barracuda 9 Installation Guide, Rev. A 21 Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50°C betragen. Die Produkthandbuch Barracuda 9 (Dokument 83329030) enthalten Anweisungen zur Beurteilung der Luftstromkonstruktion. Die Beurteilung muß sicherstellen, daß sich die Gehäusetemperatur bestimmter kritischer Komponenten bei Laufwerkbetrieb innerhalb zugelassener Grenzen hält.

Barracuda 9 Installation Guide, Rev. A 23 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.
24 Barracuda 9 Installation Guide, Rev. A 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.
Barracuda 9 Installation Guide, Rev. A 25 defined in IEC 950. Figure 4 provides the pin information for the DC power connector. To connect the DC power cable to the drive, simply insert the cable end into the drive’s DC power connector. 4. 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.
26 Barracuda 9 Installation Guide, Rev. A 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.

Replace the host system’s cover. 5. Setzen Sie das Gehäuseoberteil des Host-Systems wieder auf. Formatting the drive Warning. Formatting a drive erases all user data. Be sure that you understand this principle before formatting any hard disc drive.
28 Barracuda 9 Installation Guide, Rev. A N drives Setting the SCSI N/ND ID jumpers drives section Use the J6 connector to set the SCSI ID (see Figure 5). To change the SCSI ID, install jumpers on the appropriate pins as shown in the illustration. Drive Front Jumper Plug (enlarged to show detail) Pin 1 J6 Reserved SCSI ID = 0 (default) SCSI ID = 1 SCSI ID = 2 SCSI ID = 3 SCSI ID = 4 SCSI ID = 5 SCSI ID = 6 SCSI ID = 7 Figure 5.
Barracuda 9 Installation Guide, Rev. A 29 N drives Terminating the drive ST19171N 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 from pins 15 and 16 of connector J2 (see Figure 6). 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.

32 Barracuda 9 Installation Guide, Rev. A W/WD drives Setting the SCSI W/WD ID jumpers drives section Use the J6 jumper block to set the SCSI ID (Figure 9). To change the SCSI ID, install jumpers on the appropriate pins as shown in the illustration. Optional connections to switching circuits in host equipment are provided on J1 auxiliary to set the SCSI ID (see Figure 10).

Barracuda 9 Installation Guide, Rev. A 37 WC/DC drives Setting the SCSIWC/DC ID jumpers drives section The SCSI ID for WC and DC drives is normally set over the SCSI bus by the host system using connector contacts 39 (ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Terminating the drive ST19171WC and ST19171DC drives do not have internal terminators or any other way of adding internal termination to the drive. You must provide external termination to these drives when termination is required.
