Chapter 5 – Configuration

Setting SCSI parameters
The parameters of the SCSI connection(s) to the host(s) are set and reconfigured from the
SCSI Params submenu located at Main menu > SCSI Params menu. The settings are needed
to avoid conflict with the SCSI adapter or other SCSI devices
ACS-8960 is available in two hardware configurations: With a fibre channel
interface and with a SCSI interface. The SCSI Params menu is only present on
the SCSI interface configuration. User of the fibre channel interface model
should ignore this section.

If ACS-8960 is the only SCSI device on the bus or is at the end of a daisy chain
the termination should be enabled. If ACS-8960 is in the middle of a daisy
chain the termination should be disabled.
2.1.3 Tag
queuing
