Instantaneous +12V current peaks will exceed these values. 12A –10% tolerance is permissible during initial start of spindle and must return to ±5% before 7,200 RPM is reached. 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.
18 Barracuda 4 Installation Guide, Rev. E continued from previous page 19Where power is provided to multiple drives from a common supply, careful consideration for individual drive power requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be available to each device. 10Operating condition is defined as a third stroke seek at OD and read one track. A command is issued every 0.063 sec for N/W/WD/WC/DC drives (0.075 sec for ND drives).
Barracuda 4 Installation Guide, Rev. E 19 Initial setup information The general information beginning on this page applies to all of the Barracuda 4 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.
20 Barracuda 4 Installation Guide, Rev. E 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. Most Barracuda disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, refer to the appropriate drive section for your model. Note.
Barracuda 4 Installation Guide, Rev. E 21 Drive termination If you are installing the 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. The top example in Figure 4 shows an internal hard disc at one end of the SCSI bus with the SCSI controller at the other end (both are terminated).
22 Barracuda 4 Installation Guide, Rev. E 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. Synchronizing spindles (optional) If you are installing two or more Barracuda drives, you may synchronize their spindles to reduce the latency associated with switching from one drive to another.
Barracuda 4 Installation Guide, Rev. E 23 system requirements; however, in most cases, you will not need to change any of these jumpers for normal drive operation. Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50oC. The drive’s product manual (83328880) describes how to evaluate the air-flow design.
24 Barracuda 4 Installation Guide, Rev. E Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50oC 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.

N/ND drives 36 Barracuda 4 Installation Guide, Rev. E Terminating the drive To terminate the ST15150N drive, enable the permanently mounted IC active terminators by installing an Enable Drive Terminator jumper on J01 pins 1 and 2 as shown in Figure 11. If you install one of these models and it is not on the end of the SCSI bus, remove the jumper to disable the permanently mounted IC terminators and thereby remove internal termination from the drive.
37 Terminator power There are four possible terminator power configurations for the ST15150N drive (see Figure 12). You will not normally need to change this option and can leave the drive configured as it was shipped from the factory. The ST15150ND drive should be configured with a jumper connecting J01 pins 1 and 3 (and no jumper on J01 pins 2 and 4) as illustrated in Figure 12.
