2940UWPro-ig.qxd 12/21/98 9:55 AM Page 3 CONNECTING INTERNAL SCSI DEVICES STEP 1 Verify that each internal SCSI device you are installing has a unique SCSI ID from 0 to 6 (0 to 6 and 8 to 15 for "Wide" SCSI devices). Refer to the device's documentation to determine the SCSI ID setting. If any two SCSI devices (internal or external) you are connecting to the SCSI Card 2940UW Pro share the same SCSI ID, change the SCSI ID on one device. The SCSI Card 2940UW Pro is preset to SCSI ID 7 and should not be changed. See the SCSI Card 2940UW Pro User's Reference for additional information on SCSI IDs. STEP 2 If you are installing only one internal SCSI device, terminate that device. If you have two or more devices on each cable, terminate one device on each cable; the remaining devices must not be terminated. (The terminated device must be connected to the end of each cable, as explained in Step 5 below.) The termination setting usually is controlled by setting a jumper or a switch, or by physically removing or installing a terminator module(s). Refer to the device's documentation to enable or disable termination on your device. See the SCSI Card 2940UW Pro User's Reference for additional information on termination. STEP 3 Mount each internal SCSI device in an available drive bay inside your computer. Refer to your computer and device documentation for instructions on installing devices inside your computer. Internal SCSI Device Mounted in Drive Bay Inside Your Computer NOTE If it is difficult to reach the back of your internal SCSI devices when they are mounted in a drive bay, you can connect the internal SCSI devices to the SCSI cable and power supply (Steps 5-7 below) before mounting each device inside your computer. 3
