Seite 22: Initial Setup Information
Barracuda 4 Installation Guide, Rev. D 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 infor- mation about configuring and installing your particular model. - Seite 23 Barracuda 4 Installation Guide, Rev. D 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.
- Seite 24 Barracuda 4 Installation Guide, Rev. D 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.
- Seite 25 Barracuda 4 Installation Guide, Rev. D 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.
- Seite 26 Barracuda 4 Installation Guide, Rev. D 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 50 The drive’s product manual (83328880) describes how to evaluate the air-flow design.

- Seite 36 Barracuda 4 Installation Guide, Rev. D 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. If you do not want the system chassis to be connected to the HDA/PCB ground, you must provide a nonconductive (electrically isolating) method of mounting the drive in the host system.
