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.
