Where should termination be enabled on a SCSI bus with multiple devices connected?

Termination on a SCSI bus is crucial for ensuring that the data signals are properly managed and that communication occurs without interference or signal degradation. The SCSI bus architecture requires termination at the ends of the bus to prevent signal reflection, which can lead to data errors.

When multiple devices are connected to a SCSI bus, termination should be enabled on both ends of the bus, which typically includes the last device in the chain (commonly an external tape drive or another peripheral) and the device that acts as the SCSI controller. In this case, since the external tape drive and the DVD drive are mentioned, enabling termination on both of these devices ensures that the bus is properly terminated and can handle signal integrity more effectively.

This approach helps maintain a stable communication channel among all devices connected to the SCSI bus, facilitating reliable data transfer across multiple devices. Therefore, enabling termination on both the external tape drive and the DVD drive is aligned with best practices for handling SCSI connections.
