Quick Installation; Prepare Your Scsi Devices - Adaptec AHA-2740W User Manual

Quick Installation

The following installation procedures are intended to help experi-
enced users quickly install the AHA-2740W/2742W/2744W into an
EISA computer system.
If you are new to computer peripheral installation or would like
more information, refer to the more comprehensive instructions and
illustrations found in Installation on page 2-8.

Prepare Your SCSI Devices

Before you physically install the host adapter and connect the SCSI
devices, you must prepare your SCSI devices for installation on the
SCSI bus.
1
Terminate the last device, and only the last device, that will be
connected to each SCSI connector on the host adapter.
The device connected at the end of each SCSI connector must
have a set of resistors called terminators either installed or
enabled. All other SCSI devices installed between the last
device and the host adapter must have their terminators either
removed or disabled. In addition, termination on the host
adapter itself must be properly configured. Refer to Chapter 3,
Configuring the Host Adapter for instructions.
Refer to the SCSI device documentation for information on
enabling or disabling SCSI termination on other SCSI devices.
2
Verify that each SCSI device located on the SCSI bus is set to a
unique SCSI ID (0-7 for standard 8-bit SCSI devices; 0-15 for
16-bit Wide SCSI devices).
The default value for your host adapter is SCSI ID 7. Normally,
the host adapter should always be set to SCSI ID 7, which is the
ID that has the highest priority on the SCSI bus.
Refer to Chapter 3, Configuring the Host Adapter for instructions
on changing the SCSI ID for the host adapter. Refer to the SCSI
device documentation for information on changing the SCSI
ID on other SCSI devices.
