supplier
for details.
2.4.1 SUN Microsystems
Manufacturer:
SUN Microsystems
Mo dels:
SPARCStation 1, 1+,2, IPC, IPX, SLC, ELC, 10, 4/470,LX
Op erating System:
SunOS 4.1, 4.1.1, 4.1.2, 4.1.3; Solaris 2.0, 2.1, 2.2, 2.3, 2.4
Cables Required
To connect the SPARCStation with the
DAT-Link
you will require a cable with a
high-density 50 pin D connector
on one end and a
50 pin Centronics typeconnector
on the other end. This may also be called a
SCSI-1 to SCSI-2
cable. It should b e
available from your SUN hardware supplier or can b e ordered from your
DAT-Link
supplier.
Cho osing a SCSI ID
If you are using the standard software as supplied by SUN, then SCSI ID's 4 and 5
are reserved for tape drives, or devices such as the
DAT-Link
. If you already have
a tap e drive connected to your machine, check its SCSI ID setting which should
be either 4 or 5. You can then use the other number for the
DAT-Link
. If both
ID's are already b eing used, or if you wish to install multiple
DAT-Link
devices,
then a custom
UNIX
kernel must be built for the machine | a job for a system
administrator. Arbitrary SCSI ID's can then b e chosen in the range 0 to 6.

The SCSI ID's of all devices connected, including the
DAT-Link
, can also be checked
by halting the computer and using the
probe-scsi
command when you have the
system boot prompt, \
>
". See the
Sun System & Network Manager's Guide
sup-
plied with your workstation for details on halting and rebooting the computer.
Under Solaris 2.
x
, the
prtconf -v
command can also be used to identify the SCSI
addresses (target ID's) of the connected devices.
Connecting the
DAT-Link
The next step is to connect the
DAT-Link
to the computer. Since it is necessary to
unterminate the SCSI bus temp orarily, it is recommended that you shut-down and
turn o the computer before making the connection.

The
DAT-Link
's SCSI ID switch go es up to 9, but the 8 and 9 settings are only for factory
testing. The SUN itself uses SCSI ID 7
