Action
• 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.
Be sure to install a
terminator at each end
of the bus. One
terminator is usually
installed on the system.
Limit the bus length to
the ANSI SCSI standard
of 3 m (9.9 ft) for a
single ended (SE) cable.
Limit the number of
devices on the bus to
eight (sixteen for a wide
bus), including the SCSI
controller.
With the SDLT power
switch off, check the
SDLT power
connections.
