14 Elite 47 Installation Guide, Rev. B General description Elite 47 SCSI disc drives are high-speed, random-access digitaldata 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.

Elite 47 Installation Guide, Rev. B 19 SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system’s SCSI controller usually uses the ID that has the highest priority interrupt in the SCSI I/O system. This is always ID7. ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority in a 16-bit I/O system. The lower priority SCSI IDs are normally used for other SCSI devices such as this Elite disc drive. Note.
20 Elite 47 Installation Guide, Rev. B Most Elite 47 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 Figure 2.
Elite 47 Installation Guide, Rev. B 21 user’s manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Elite 47 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.

30 Elite 47 Installation Guide, Rev. B Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The MTBF (mean time between failure) value is based on operating at a local ambient temperature of 30°C (86°F). The maximum ambient temperature is 50°C. The drive’s product manual (83329280) describes how to evaluate the air-flow design.
Elite 47 Installation Guide, Rev. B 31 Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50°C betragen. Die Produkthandbuch Elite 47 (Dokument 83329280) enthalten Anweisungen zur Beurteilung der Luftstromkonstruktion. Die Beurteilung muß sicherstellen, daß sich die Gehäusetemperatur bestimmter kritischer Komponenten bei Laufwerkbetrieb innerhalb zugelassener Grenzen hält.

Elite 47 Installation Guide, Rev. B 33 Mounting the drive and connecting cables Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. 1. Mount the drive to the host system’s chassis using four 6-32 UNC screws.
34 Elite 47 Installation Guide, Rev. B 1. Befestigen Sie das Laufwerk mit vier 6-32-UNC-Schrauben am Gehäuse des Host-Systems. Die beiden Seiten des Laufwerkes sind mit jeweils zwei Befestigungslöchern versehen, die Unterseite des Laufwerkes weist vier weitere Befestigungslöcher auf. Gemessen von der Außenfläche des Gehäuses dürfen die Schrauben maximal 4,318 mm in die Befestigungslöcher des Gehüuses hineinragen. Die Schrauben müssen gleichmäßig, jedoch nicht zu fest, angezogen werden.
Elite 47 Installation Guide, Rev. B 35 for the DC power connector. To connect the DC power cable to the drive, simply insert the cable end into the drive’s DC power connector. 4. Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an. Das Kabel darf nicht gedehnt oder gedrückt werden und es darf den Luftstrom zur Kühlung des Systems nicht behindern. Das Laufwerk wird über einen 4-poligen, neben dem SCSIAnschluß befestigten Steckverbinder mit Gleichstrom versorgt.
36 Elite 47 Installation Guide, Rev. B Note. Signal ground on the printed circuit board assembly (PCBA) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. Ensure the equipment in which you have mounted the drive is connected directly to the HDA. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions.
