Appendix A Ultra320 SCSI Configuration 15

Cabling and Termination

Use the following cabling guidelines to ensure proper device cabling and

termination.

Cabling

In order to maintain Ultra320 SCSI performance, all cables used must be Ultra320

SCSI compliant.

Termination

■ The SCSI bus must be correctly terminated at the end of the bus. Most Sun

devices use auto-termination. See the documentation that came with the device.

■ This host adapter has active terminators with an automatic means of enabling and

disabling the termination. All the termination circuit derives its power from the

PCI or SCSI bus. When the PCI bus power is removed, active SCSI termination is

maintained if the other SCSI device supplies power to the Term Pwr pins of the

SCSI bus.
