Page A-9Roadrunner SCSI Bus Compatibility
3.If a computer does not have a SCSI disk drive, but does have one or more
SCSI magnetic tape or CD-ROM drives, then one of these devices will be
configured to supply termination power.
4.If a computer with one or more SCSI peripherals is cabled to a subsystem
with additional SCSI devices, one SCSI device in the host computer would
normally be configured to supply termination power for the bus.
You should avoid having a SCSI device in both the host computer and the
subsystem configured to supply termination power. Ideally, you want the
source of the termination power for the bus to be supplied by one power
source only!
For information on how to configure terminator power on SCSI hard disk and magnetic
tape peripherals, see the following documents:
Each SCSI disk drive shipped by Alpha Micro has a one page notice with
jumper configuration information, including instructions on how to configure
termination power.
