[. . . ] 7 Minimum current loading for each supply voltage is not less than 7% of the maximum operating current shown. 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. 14 Read track is defined as repeat reads of track 15 with an 88% duty cycle. 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. 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. To change the SCSI ID, install jumpers on the appropriate pins as shown in the illustration. If, after completing the installation process, the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. 20 J4A SCSI I/O Connector J01 Elite 9 Installation Guide, Rev.

Figure 2. B 21 Terminating the drive 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. [. . . ] The output of a power supply must meet SELV (safety extra low voltage) as defined in IEC 950. To connect the DC power cable to the drive, simply insert the cable end into the drive's DC power connector. Elite 9 Installation Guide, Rev. Schließen Sie das 50-polige SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an (wie bereits in Abbildung 1 gezeigt). Das Kabel darf nicht gedehnt oder gedrückt werden und es darf den Luftstrom zur Kühlung des Systems nicht behindern. [. . . ]
