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.
