Installing the LSI22915A

Version 1.3

Copyright © 2000–2003 by LSI Logic Corporation. All rights reserved.

The LSI22915A automatically controls SCSI bus termination for these
three different bus configurations:

•

Section 2.2.6.1, “Internal SCSI Devices Only”

•

Section 2.2.6.2, “External SCSI Devices Only”

•

Section 2.2.6.3, “Internal and External SCSI Devices”

2.2.6.1

Internal SCSI Devices Only

If you connect only internal SCSI devices to the host adapter, you must
terminate the last internal device on the SCSI bus and disable
termination on all other devices. Termination on the host adapter is
automatically enabled.

shows how termination is set for a configuration with internal

SCSI devices only.
