Product Information
Rear Panel Components
SCSI Connectors
There is one Single-Ended/Low-voltage Differential (SE/LVD) SCSI connector on the rear
panel. This connector will support SE SCSI and LVD SCSI, but not both at the same time.
Use the SCSI connector to connect external SCSI devices such as hard disk drives, optical
disk drives, DDS-format tape drives, and CD ROM drives.
Consult the documentation that accompanies each SCSI device for specific information
concerning its use. Also see Appendix C, “SCSI Connections,” for information about
connecting SCSI devices to the J6700 workstations.
CAUTION Do not mix NSE and LVD SCSI devices on the same SCSI bus as this can
cause reduction of device performance.
Audio Connectors
Your workstation has audio input and output capability through external input and output
connectors on the rear panel and through an internal speaker. The rear panel contains the
line input jack, line output jack, headphone jack, and microphone jack connectors.
Figure 1-6. Audio Connectors
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 1-4 on the next page provides a summary
of the audio electrical specifications.
