Figure 2.16 Internal and External SCSI Device Termination

2.3.4 Internal SCSI Connections for Both Internal Connectors

If you have internal SCSI device connections to both internal connectors
of a channel, you must terminate the internal devices on each end of the
SCSI bus. You must disable the termination on all other devices.
Termination on the host adapter is automatically disabled in this case.

Caution:

Remember, you must not use the external connector for a
channel if you use both internal connectors for that
channel.
