To connect an external SCSI device, or a SCSI expansion box, follow these steps:
1. Set the drive jumpers or switches for the desired SCSI ID.
2. Remove the SCSI terminator and connect the option’s SCSI cable to the port. Be sure
that you use a cable with a SCSI 50-pin high density type connector.
3. Terminate the new end of the bus at the last external SCSI device, using the
appropriate terminator. Make sure that any other external SCSI devices have their
terminators removed or disabled.
To Check expansion box connections, enter the following from the console prompt:
