Troubleshooting the SDLT Drive
The system does not
recognize the SDLT
drive
The SCSI bus might not
be correctly terminated.
•
If the SDLT drive is
the last or only
device on the bus,
make sure the
terminator is
installed on the drive.
•
If the SDLT drive is
not the last or only
device on the bus,
check the cable
connections and
make sure that the
terminator is
installed at the end
of the bus.
The SCSI terminator
might not be at the end
of the bus, or more than
two terminators might
be present.
Be sure to install a
terminator at each end
of the bus. One
terminator is usually
installed on the system.
The SCSI bus might be
too long.
Limit the bus length to
the ANSI SCSI standard
of 3 m (9.9 ft) for a
single ended (SE) cable.
Too many devices might
be on the bus.
Limit the number of
devices on the bus to
eight (sixteen for a wide
bus), including the SCSI
controller.
The SDLT drive does
not power up
The SDLT drive has no
power.
With the SDLT power
switch off, check the
SDLT power
connections.
