Configure The Host Adapter - Adaptec AHA-2740W User Manual

To connect additional internal Wide SCSI devices, you will need
to obtain a 68-pin SCSI ribbon cable with enough 68-pin connec-
tors to accommodate all of your internal Wide SCSI devices.
5
To connect external 16-bit Wide SCSI devices, use a 68-pin
shielded cable with 68-pin P-cable connectors to connect the
first external Wide SCSI device to the external Wide SCSI con-
nector on the host adapter.
To connect subsequent external Wide SCSI devices, you will
need to obtain additional 68-pin shielded cables to chain the
devices together.
Note:
Only two of the three SCSI connectors can have
devices connected at any one time. Connecting devices
to all three connectors will result in an improperly ter-
minated SCSI bus. The total number of SCSI devices
that can be connected to the host adapter is 15.

If you are using the floppy controller on the AHA-2742W and
AHA-2744W, connect one end of the 34-pin floppy ribbon
cable to the floppy connector on the host adapter; connect the
other end to the connector on the first floppy drive (Drive A).
To connect a second floppy drive, plug the middle connector of
the floppy ribbon cable to the connector on the second floppy
drive (Drive B).

Reinstall your cover and reconnect all system and peripheral
power cables.

puter system. Chapter 3, Configuring the Host Adapter provides a
comprehensive description of how the utility works; however, the
basic steps involved include the following:
