Product Information Rear Panel Components SCSI Connectors There are two SCSI connectors on the rear panel: one NSE (Narrow Single-Ended) SCSI-2 connector, and one Ultra2 Wide LVD (Low Voltage Differential) SCSI connector. Use the SCSI connectors to connect external SCSI devices such as hard disk drives, optical disk drives, DDS-format tape drives, and CD drives. Consult the documentation that accompanies each SCSI device for specific information concerning its use. Also see Appendix C, "SCSI Connections," starting on page 189 for information about connecting SCSI devices to the J5000 and J7000 workstations. CAUTION Do not connect NSE SCSI devices to the LVD SCSI connector, or vice versa, because damage may occur. Currently Hewlett-Packard does not support mixing NSE and LVD devices on the same SCSI bus. NOTE When attaching external SCSI devices, be sure to terminate the last device on each external SCSI bus. (Terminators are included in a small plastic bag shipped with the workstation.) If there are no external SCSI devices, the terminators must be installed directly on the connectors on the rear panel. Audio Connectors The J5000 and J7000 workstations have audio-input and -output capabilities through external input and output connectors on the rear panel and through an internal speaker. The sound is 16-bit, 44 kHz (CD-quality). Figure 1-10 shows the four audio connectors on the rear panel. Figure 1-10. Audio Connectors Microphone In Headphones Out Line Out Line In The audio connectors are standard stereo audio mini-jacks. Hewlett-Packard recommends using gold-plated plugs available through audio retailers for best quality recording and playback through the external connectors. Table 1-5 on the next page provides a summary of the audio electrical specifications. Chapter 1 27
