As if things were not already complicated enough with this issue, there is
one additional caveat that I feel should be mentioned here. Just because
your computer has an external SCSI connector does not necessarily mean that
you can use it. Some SCSI controllers (e.g. Adaptec AHA-2940 Ultra Wide)
have two internal SCSI connectors and one external SCSI connector. Due to
issues related to SCSI termination, if you are using both internal
connectors, then you cannot use the external connector. This fact is
clearly stated by the manual. I would suggest that before using an
external SCSI connector, you check the documentation for your SCSI
controller or with its manufacturer to determine if there are any instances
where the external connector cannot be used.
