Plug the connector at the other end of the cable to
either one of the SCSI connectors on the external
SCSI device.

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-2940/2940W includes the onboard, menu-
driven SCSISelect configuration utility, which allows
you to change host adapter settings without open-
ing 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-2940/2940W 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. Your host adapter
is ready for operation and you can proceed to Install-
ing Device Drivers on page 10.
