2.Verify that all connections between the drive and the host system are correctly installed.

2.Prüfen Sie, ob alle Verbindungen zwischen dem Laufwerk und dem Host-System korrekt hergestellt sind.

3.Verify that you have correctly installed jumpers.

3.Stellen Sie sicher, daß die Kennungsbrücken installiert sind.

4.Connect the 50-pin SCSI cable into the drive’s SCSI connector (shown earlier in Figure 1). Take care not to stretch or crimp this cable, and do not block the system’s cooling air flow with the cable.

The drive receives DC power through a 4-pin connec- tor mounted next to the SCSI connector. The output of a power supply must meet SELV (safety extra low voltage) as defined in IEC 950. Figure 4 provides the pin information for the DC power connector. To con- nect the DC power cable to the drive, insert the cable end into the drive’s DC power connector.

4.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.
