The table below shows how termination must be set on the host

adapter for the three possible configurations of devices on the SCSI

bus. If you need to change the termination setting, follow the

instructions in Terminating the SCSI Bus on page 3-2.

The following sections explain each of the three configurations.

Termination for Internal Devices Only

When only internal devices are connected to the host adapter, the

last device connected to the ribbon cable should be terminated and

the host adapter should be terminated, as shown in Figure 3-2.
