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. Remove Cable C connecting Backplanes A and B. Store the cable for

future use.

2. 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.

3. Connect Cable D (the optional SCSI accessory cable) to the top connector

on Backplane B, and 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.
