Step 3: Align the SCSI cable's colored stripe with Pin-1 on the SCSI device connector, and then plug it in. Internal SCSI Device Pin 1 Colored Stripe (typically red or blue) Step 6: Connect a DC power cable from your computer's power supply to the power connector on the SCSI device. Power Input Connector on Pin 1 the Back of the Drive DC Power Cable (from the power supply) Colored Stripe (typically red or blue) Step 4: Attach the remaining devices using the remaining connectors. These devices should not be terminated. Step 5: Terminate the SCSI device that is attached at the end of the internal SCSI cable. Caution: If you are attaching an AHA-2910C between two terminated SCSI devices, or if you are using both internal and external SCSI devices, you must disable host adapter SCSI termination with SCSISelect, (see Using SCSISelect on page 7). This device must be terminated, since it is connected at the end of the cable. Step 7: Replace the computer cover. Installing External SCSI Devices Connecting One Device Step 1: Plug one end of the 50-pin high-density external SCSI cable into the host adapter's external SCSI connector. Step 2: Plug the other end of the external SCSI cable into one of the connectors on the external SCSI device. Step 3: Enable the device termination or attach a terminating plug to the device. You would not terminate this device. External SCSI Cable Terminating Plug 4
