PowerDomain 2940UW with 50-pin and 68-pin Internal Devices
When both the 50-pin and 68-pin internal connectors on the
PowerDomain 2940UW have SCSI devices connected to them,
you must enable termination on the last SCSI device connected 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 four internal devices connected to
two internal cables. One cable is attached to the 50-pin (Narrow)
connector, and the other cable is attached to the internal 68-pin
(Wide) connector.
