Installing the A5150A Adapter

Connecting the SCSI Peripherals

Step 3. If you need to connect more than one external SCSI device to your host bus adapter, chain them together with shielded external SCSI cables.

If auto termination has been disabled and you wish to terminate an external connector on the HBA, use HP product number A5296A, VHDCI LVD/SE terminator.

Making Internal SCSI Bus Connections

Step 1. Identify pin 1 on adapter connector J4 or J5 (internal 68-pin SCSI connector). Pin 1 of the connector is typically marked by the number 1 or a small triangle.

Step 2. Identify pin 1 on either end of a 68-pin SCSI ribbon cable. Pin 1 is typically marked with a contrasting color on the pin-1 end of the cable connector (for example, red).

Step 3. After assuring pin-1 orientation, attach the SCSI cable to the 68-pin internal adapter connector (J4 or J5). Connector the other end of the cable to the SCSI connector on the internal peripheral device.

Step 4. If you need to connect more than one internal SCSI device to your host bus adapter, you can chain them together (connect them serially).

Step 5. Refer to “SCSI Bus Termination” on page 29 for information on termination.

If auto termination has been disabled and you wish to terminate an internal connector on the HBA, use HP product number C2370A, SCSI LVD/SE VHDTS68 terminator.
