1 NEXT PREVIOUS JUMP CONTENTS INDEX SETTING UP THE JUKEBOX CONNECTING THE JUKEBOX WITH OTHER SCSI PERIPHERALS Connecting this jukebox with other peripherals on the bus is shown in Figure 1-5. Important: Other devices on the same bus as this jukebox will affect jukebox performance. Consider the following issues if you are deciding whether to connect other devices onto the same bus. • How will the jukebox be used: archiving, backup, near-line storage? What performance must be maintained? • How will the additional peripheral will be used? How much demand will the additional peripheral place on the bus? • What is the bus length available? A basic review of SCSI and a discussion of the issues involved with connecting devices on a bus is in Appendix B. Caution: Do not connect a high-voltage differential device onto the same bus as this jukebox. Damage to the high-voltage differential device interface electronics can occur. Important: Do not add a single-ended device onto the bus if you intend the bus to be a low-voltage differential bus. The bus will switch to single-ended mode if any single-ended devices are detected. If you mix single-ended and low-voltage differential devices (causing single-ended operation) on total cabling longer than 9.8 feet (3 metres), SCSI bus problems could occur. This jukebox will operate in single-ended mode, but must be on a bus that is 9.8 feet (3 metres) or less. 13

ERIPHERALS
Connecting this jukebox with other peripherals on the bus is shown in
Figure 1-5
.
Important:
Other devices on the same bus as this jukebox will affect jukebox performance. Consider the following issues if you are deciding
whether to connect other devices onto the same bus.
•
How will the jukebox be used: archiving, backup, near-line storage? What performance must be maintained?
•
How will the additional peripheral will be used? How much demand will the additional peripheral place on the bus?
•
What is the bus length available?
A basic review of SCSI and a discussion of the issues involved with connecting devices on a bus is in Appendix B.
Caution:
Do not connect a high-voltage differential device onto the same bus as this jukebox. Damage to the high-voltage differential device
interface electronics can occur.
Important:
Do not add a single-ended device onto the bus if you intend the bus to be a low-voltage differential bus. The bus will switch to
single-ended mode if any single-ended devices are detected.
If you mix single-ended and low-voltage differential devices (causing single-ended operation) on total cabling longer than 9.8 feet
(3 metres), SCSI bus problems could occur. This jukebox will operate in single-ended mode, but must be on a bus that is 9.8 feet (3
metres) or less.
