CONNECTING SCSI PERIPHERALS A total of 15 SCSI peripherals can be connected to the SCSI Card 2940U2W. Before connecting peripherals to the SCSI Card 2940U2W, be sure to also review Setting Up SCSI Peripherals on page 3. STEP 1 68-pin Internal Ultra2 SCSI Connector Use the 68-pin internal Ultra2 SCSI connector to connect internal Ultra2 peripherals. The connector is an Ultra2 Low Voltage Differential, Single Ended (Ultra2-LVD/SE) connector. The internal Ultra2 cable included in the kit allows up to four internal Ultra2 peripherals. If you have more than four Ultra2 peripherals, you will need to obtain an Ultra2 cable with enough connectors to accommodate all of your Ultra2 peripherals. Follow these steps to connect your internal Ultra2 peripherals: NOTE We recommend keeping your Ultra2 peripherals separate from your non-Ultra2 peripherals. Connecting a non-Ultra2 peripheral to the Ultra2 SCSI connector forces the Ultra2 SCSI segment and any attached peripherals to drop down to Ultra SCSI performance levels (40 MBytes/sec). (See "Bus Segments on the SCSI Card 2940U2W" on page 2.) Locate the 68-pin internal Ultra2 SCSI cable in the package. STEP 2 Connect to SCSI Card 2940U2W Connect to Ultra2 Peripherals Built-in Terminator Plug the long end of the cable to the Ultra2 connector on the SCSI Card 2940U2W (connectors are labeled "Ultra2-LVD/SE").
