2 Elite 9 Installation Guide, Rev. B • 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.
Elite 9 Installation Guide, Rev. B 3 read and followed to minimize or eliminate the risk of personal injury. The warnings point out conditions or practices that may endanger you or others. The cautions point out conditions or practices that may damage the unit, possibly making it unsafe for use.
4 Elite 9 Installation Guide, Rev. B • Ensure that the internal temperature of the rack or cabinet does not exceed the limits defined for the drive when the drive is mounted in an equipment rack or cabinet. When units are stacked vertically, pay atten- tion to the top where temperatures are usually highest.

Elite 9 Installation Guide, Rev. B 19 Setting the 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 ava.

Elite 9 Installation Guide, Rev. 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.
22 Elite 9 Installation Guide, Rev. B To terminate ST410800N and ST410800W drives, en- able the permanently mounted IC terminators by install- ing a jumper on J4A pins 19 and 20 as shown in Figure 4.
Elite 9 Installation Guide, Rev. B 23 ST410800ND and ST410800WD (differential) drives are shipped with terminators (part number 15479501) in- stalled on the circuit board. Figure 5 illustrates the locations of the terminators. To remove termination from the drive, carefully lift the terminators from their sockets.

Elite 9 Installation Guide, Rev. B 27 Figure 9 illustrates a typical synchronized spindle configuration. After connecting each drive with spindle sync cables, you must designate a master spindle sync reference source. This master source is normally a disc drive located on the same SCSI bus as the other drives you want to synchronize with.
28 Elite 9 Installation Guide, Rev. B Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 45 o C. The drive’s product manual (83328860) describes how to evaluate the air-flow design.

36 Elite 9 Installation Guide, Rev. B 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 separate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts.
Elite 9 Installation Guide, Rev. B 37 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.
