Getting Started
This document provides the steps required for installa-
tion of the AHA-2740W and AHA-2742W single-ended,
and the AHA-2744W differential EISA-to-Fast, Wide
SCSI Host Adapters. The AHA-2740W and AHA-2742W
support single-ended SCSI, while the AHA-2744W
supports differential SCSI. In this document, the
AHA-2740W,AHA-2742W,andAHA-2744Warereferred
to jointly as the AHA-2740W/2742W/2744W.
Procedures for all three adapters are the same except
when regarding the onboard floppy controller on the
AHA-2742W and AHA-2744W. Installation of the host
adapter includes the following steps:
1Installing the AHA-2740W/2742W/2744W host
adapter in an EISA system.
2Installing the SCSI cable(s) and SCSI peripheraldevices.
3Terminating the SCSI bus.
4Setting the SCSI ID.
5Adjusting the host adapter configuration settings if
necessary.
