ST15150N/ND/W/WD Installation Guide, Rev. B continued from previous page Operating condition is a third-stroke seek at OD and Read One Track. The command is issued every 0.075 seconds. No terminator power. See Section 11.7.3.4 in the Barra- cuda 4 Product Manual. With all power-saving features enabled. - Seite 20 ST15150N/ND/W/WD Installation Guide, Rev. B Each option-jumper illustration identifies the original equipment manufacturer (OEM) default factory setting. These settings are the most common ones used but are not necessarily the ones set for your particular system. Write down the original jumper settings before you make any changes.
- Seite 21 ST15150N/ND/W/WD Installation Guide, Rev. B Most Barracuda disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, install jumpers on the appropriate pins as shown in the illustration provided for your model (N/ND or W/WD). If, after completing the installation process, the drive’s LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may...

- Seite 24 ST15150N/ND/W/WD Installation Guide, Rev. B Terminating the drive If you are installing a Barracuda 4 drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI “device” is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus.
- Seite 25 ST15150N/ND/W/WD Installation Guide, Rev. B of the SCSI bus, remove the Enable Drive Terminator jumper (see Figure 6). Removing the jumper disables the permanently mounted IC terminators and there- fore removes internal termination from the drive. For ST15150N drives, the Enable Drive Terminator jumper is located on J01 pins 1 and 2.

- Seite 32 ST15150N/ND/W/WD Installation Guide, Rev. B Synchronizing spindles in multiple drive configurations If you are installing two or more Barracuda drives, you may (optionally) want to synchronize their spindles to reduce the latency associated with switching from one drive to another. Spindle sync cables are used to connect the drives.
- Seite 33 ST15150N/ND/W/WD Installation Guide, Rev. B For W and WD drives, use pins 11 and 12 on the J5 connector to attach the spindle sync cable. Pin 11 provides the reference index signal (REFSIG+) and pin 12 provides ground (GND). See Figure 13. SCSI I/O DC Power Connector...
- Seite 34 ST15150N/ND/W/WD Installation Guide, Rev. B Figure 14 illustrates a typical synchronized spindle configuration. After connecting each drive with spindle sync cables, you must designate a master spindle sync reference source. This master source is normally a disc drive located on the same SCSI bus as the other drives you want to synchronize with.
- Seite 35 ST15150N/ND/W/WD Installation Guide, Rev. B Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The minimum ambient temperature is 5 C. The maximum ambient temperature is 50 The drive’s product manual (83328880) describes how to evaluate the air-flow design. The evaluation consists of ensuring that the case temperatures of certain critical components remain within acceptable limits during drive operation.

Seite 36: Kühlung Des Systems
Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50 C betragen. Die Produkthandbuch Barracuda 4 (Dokument 83328880) enthalten Anweisungen zur Beurteilung der Luftstromkonstruktion. Die Beurteilung muß sicherstellen, daß sich die Gehäusetemperatur bestimmter kritischer Komponenten bei Laufwerkbetrieb innerhalb zugelassener Grenzen hält. - Seite 37 ST15150N/ND/W/WD Installation Guide, Rev.

If you do not want the system chassis to be connected to the HDA/PCB ground, you must provide a nonconductive (elec- trically isolating) method of mounting the drive in the host system.
- Seite 45 ST15150N/ND/W/WD Installation Guide, Rev. B 5. 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. It is not necessary to format a drive which has previously been used to store data, unless your intention is to erase all user data.
