[. . . ] Spindle sync cables are used to connect the drives. After connecting each drive with spindle sync cables, designate a master spindle sync reference source. This master source is usually a disc drive located on the same SCSI bus as the other drives you want to synchronize with. To designate a drive as the master, use SCSI interface commands. Refer to the Barracuda 4 Product Manual for information about using these commands. For information about how to synchronize the spindles for your drive, refer to the appropriate drive-specific section. Other applicable jumper options Barracuda 4 drives are designed for use in a variety of systems. Some installations may require you to change one or more of the other jumpers to meet specific 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. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation. We recommend orienting the drive or directing the air flow in a way that creates the least amount of air-flow resistance while providing air flow above the circuit boards and around the head and disc assembly (HDA). Also, choose the shortest possible path between the air inlet and exit. This minimizes the distance traveled by air that is heated by the drive and by other nearby heat sources. Figure 5 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. 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.
