Figure 3-8. Duplexing Using Internal SCSI Cables
Duplexing with a SCSI Host Bus Adapter Card
Follow these steps to duplex the SCSI hard drives using a SCSI Host Bus Adapter
card (see Figure 3-9).
1. Disconnect Cable B from SCSI Channel A (on the system board), and
connect it to Channel 0 on the SCSI host bus adapter card.
Ensure the cable is not looped at the Channel 0 connection. The cable
should appear as shown in Figure 3-10.
2. Disconnect Cable C from the bottom connector of Backplane A and
connect it to Channel 1 on the SCSI Host Bus Adapter card.
Ensure the cable is not looped at the Channel 1 connection. The cable
should appear as shown in Figure 3-10.
3. Plug a SCSI terminator into the bottom connector on Backplane A and
Backplane B.
