2 Plug the connector at one end of the external SCSI

cable into the host adapter’s external SCSI

connector.

3 Plug the connector at the other end of the cable to

either one of the SCSI connectors on the external

SCSI device.

4 To connect other external SCSI devices, daisy-

chain each device to the previous device until all

external SCSI devices have been connected.

Using the LED Connector

(Optional) Most computers have an LED disk activity

light on the front panel. If you disconnect the cable

from the LED connector on the motherboard and

connect it to the LED connector on the host adapter,

the LED on the front panel of the computer will light

whenever there is activity on the SCSI bus.

Reassembling the Computer

Be sure all power switches are OFF, then replace the

computer chassis cover and reconnect the power

cables to your computer and peripherals. Before

turning on your computer and peripherals, review

the following section, Configuring the Host Adapter. It

may be necessary to configure the host adapter.

Configuring the Host Adapter

The AHA-2940Ultra/2940Ultra Wide includes the

onboard, menu-driven SCSISelect configuration util-

ity, which allows you to change host adapter settings

without opening the computer or handling the

board. SCSISelect also contains SCSI disk utilities

that let you low-level format or verify the disk media

of your SCSI hard disk drives.

SCSISelect Default Settings

The AHA-2940Ultra/2940Ultra Wide has the default

settings shown in the table on the following page.

The default settings are appropriate for most PCI

systems. If you do not need to change any of the

default settings, there is no need to run SCSISelect.
