Differential Ultra Wide SCSI
Prior to beginning the cabling, identify the configuration for your installation. Note the card locations in the illustrations for each configuration. Install your cards and connect the cabling based on the procedures and diagrams shown. The diagrams depict the configuration using the minimum number of controller channels.
Differential Converter Card
Two Single - Bus Cabinets
With this configuration you will have up to fourteen
(14)disk drives per differential host adapter channel. Due to the fourteen drives per channel limitation, two disk drive slots will not be available.
If you are using multiple controllers you can expand your capacity by using up to four controllers per CPU system. Refer to “Default Configurations” later in this section for information on special SCSI ID settings.
1Power off your computer system or workstation.
2Be sure to complete the “Setup” and “Component Installation” sections described earlier in this Guide. The DEU ships from the factory with I/O Interface cards installed in both card slots. Therefore during the installation, you may be required to remove one or both I/O Interface cards.
3Identify the subsystem which will be the master cabinet. Loosen the two thumb screws and remove the I/O Interface card installed in the upper or right side card slot of the master cabinet.
