PowerDomain 2940UW with 50-pin Internal and 68-pin External

Devices

When both the 50-pin (Narrow) internal and 68-pin (Wide)

external connectors of the PowerDomain 2940UW have SCSI

devices attached to them, you must enable termination on the last

SCSI device attached to each connector, and you must set

termination on the PowerDomain 2940UW to Automatic or Wide-

to-narrow. (See Setting Termination on page 3-7 for instructions.)

The following illustration shows two internal devices connected to

an internal cable, which is attached to the 50-pin connector, and

three external devices connected by three external cables. One

external cable is also attached to the 68-pin external connector.
