2.2.3.1 Making Internal SCSI Bus Connections
This section provides step-by-step instructions about making internal
SCSI bus connections. If you have no internal devices to connect,
proceed to Step 4.
Step 1. Plug one end of a SCSI ribbon cable into an appropriate
connector, J2, J4, or J5. The example in
Figure 2.4 shows a
wide cable.
Channel A (J2 and J4) supports SE mode. Channel B (J5)
supports SE and LVD modes.
