Installing the A6829A Adapter

Specifying SCSI Parameters

Auto Termination

When you configure the A6829A adapter’s auto termination parameter, you specify the adapter’s role in the SCSI bus termination, because the adapter might be a point of termination.

For more information on SCSI bus termination, including a tutorial, you can visit HP IT Resource Center (ITRC) at http://itrc.hp.com.

Controlling Auto Termination

You can control auto termination in the A6829A adapter (see “Using the Jumper for Controlling Auto Termination” on page 40) depending upon the HP-UX system in which the adapter is installed (see Table 2-2 on page 24).

Summary of Auto Termination Configurations

Table 2-4 summarizes the possible A6829A auto termination configurations.
