[. . . ] These peaks should measure 5 msec duration or less. 7 Minimum current loading for each supply voltage is not less than 7% of the maximum operating current shown. 8 Use separate ground returns for +5V and +12V supplies. 9 Where power is provided to multiple drives from a common supply, carefully consider individual drive power requirements. Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device. 10 Operating condition is a third stroke seek at OD and read one track. See Section 11. 7. 3. 4 in the Elite 9 Product Manual. continued 18 Elite 9 Installation Guide, Rev. B continued from previous page 12 All power-saving features are enabled. 13 Seeking is defined as a third-stroke seek at OD. 14 Read track is defined as repeat reads of track 15 with an 88% duty cycle. 15 Operating condition is a third-stroke seek at OD and read 1 track. A command is issued every 60 msec for ST410800W drives and every 72 msec for ST410800WD drives. 16 Read track is defined as repeat reads of track 15 with a 45% duty cycle at 00. Initial setup information The following topics are presented to guide you through the installation process. These topics are presented in the order you should follow to properly install the drive. · · · · · · · Setting the SCSI ID jumpers Terminating the drive Changing other applicable jumper options Synchronizing spindles Providing adequate cooling Mounting the drive and connecting cables Formatting the drive Each option-jumper illustration identifies the original equipment manufacturer (OEM) default factory setting. These are the most commonly used settings but are not necessarily the ones set for your particular system. Elite 9 Installation Guide, Rev. B Setting the SCSI ID jumpers 19 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 (ID7 in non-wide systems); therefore the lower-numbered SCSI IDs are normally used for the other SCSI devices such as this Elite disc drive. Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2). Other controllers do not allow this; refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. Use connector J4A to set the SCSI ID (Figure 2). [. . . ] Das Laufwerk wird über einen 4-poligen, neben dem SCSI-Anschluß befestigten Steckverbinder mit Gleichstrom versorgt. Der Ausgang eines Netzteils muß SELV (safety extra low voltage) nach IEC 950 entsprechen. Abbildung 12 zeigt die Steckerbelegund für den Gleichstromanschluß. Zum Anschluß des Gleichstromkabels an das Laufwerk das Kabelende in den Gleichstromanschluß des Laufwerkes stecken.
