Seite 5: Important Safety Information And Precautions
• Ground yourself to the drive whenever the drive elec- tronics are or will be exposed. Connect yourself to ground with a wrist strap (Seagate part number 12263496). Connection may be made to any grounded metal assembly. As a general rule, remember that you and the drive electronics must all be grounded to avoid potentially damaging static discharges. - Seite 6 Barracuda 2LP Installation Guide, Rev.

Seite 16: General Description
Barracuda 2LP Installation Guide, Rev. E General description Barracuda 2LP SCSI disc drives are high-speed, ran- dom-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. - Seite 17 Barracuda 2LP Installation Guide, Rev. E Characteristics ST31250 ST32550 Interface Fast SCSI-2 Fast SCSI-2 Capacity Unformatted 1,205.3 Mbytes 2,541.3 Mbytes Formatted 1,020.9 Mbytes 2,147.4 Mbytes Recording Cylinders (user) 3,711 3,510 Read/write data heads 5 Servo heads Avg bytes/track 64,160 64,160 Seek time Average read 8.0 msec...

- Seite 20 Barracuda 2LP Installation Guide, Rev. E Measured with an average reading DC ammeter. Instanta- neous +12V current peaks will exceed these values. A −10% tolerance is permissible during initial start of the spindle but must return to ±5% before reaching 7,200 RPM. 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.
- Seite 21 Barracuda 2LP Installation Guide, Rev. E No terminator power. See Section 11.7.3.4 in the Barra- cuda 2LP Product Manual. All power-saving features are enabled (ASA II code only). Seeking is defined as a third-stroke seek at OD. The com- mand is issued every 20 msec. Read track is defined as repeat reads of track 15 with a 78% duty cycle on N models, 32% duty cycle on W models, 48% duty cycle on WC models, 60% duty cycle...

Seite 22: Initial Setup Information
Barracuda 2LP Installation Guide, Rev. E Initial setup information The general information beginning on this page applies to all of the Barracuda 2LP 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. - Seite 23 Barracuda 2LP Installation Guide, Rev. E *This mounting procedure does not apply to WC or DC model drives. To mount a WC or DC drive, plug the drive into the system's single connector attachment (SCA) position on the system's back panel. SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID.
- Seite 24 Barracuda 2LP Installation Guide, Rev. E Also check your system or controller user’s manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Barracuda 2LP drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain.
- Seite 25 Barracuda 2LP Installation Guide, Rev. E For information about how to terminate your drive, refer to the appropriate drive-specific section. 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.
- Seite 26 Barracuda 2LP Installation Guide, Rev. E Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50 The drive’s product manual (83328930) 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 33 Barracuda 2LP Installation Guide, Rev. E Note. Signal ground on the power control board (PCB) and the head and disc assembly (HDA) are con- nected together in this drive and you cannot sepa- rate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts.
- Seite 34 Barracuda 2LP Installation Guide, Rev. E Systemgehäuse nicht an die HDA/PCB-Erdung anschließen wollen, müssen Sie das Laufwerk auf nichtleitende Weise (galvanisch isoliert) im Host- System einbauen. Die daraus u.U. resultierende verstärkte elektromagnetische Strahlung fällt in den Zuständigkeitsbereich des Systemdesigners. 5. Replace the host system’s cover. 5.
