CBI-1010
devices
must
be set from SCSI
ID
0 to
6.
Normally, the assignment of SCSI
Target ID starts
with
SCSI ID 0
on
single function boards.
The factory setting of the
CBI-I0I0/TM is four disk devices
(SCSI
ID=O
to 3)
and
three tape devices
(SCSI
ID=4 to
6).
If
you have more
than
four disks
drives
or
three tapes drives
you
must use the On-Board Utility to change the
configuration;
if
you
do
not,
you
do
not need to change the configuration.
SCSI Device Installation Procedures
To install
SCSI
devices follow the procedures below:
1 Connect SCSI cables as listed below for the specified mode:
For
single-ended
mode:
Connect a SCSI cable from the back panel
at
the la-
bel "Single-Ended" to the
SCSI devices (see "Cable Specifications"). The
total of the internal
and
external cable lengths
must
not
exceed 9.9 feet at
10
MBytes/ second. See Figure 3-10.
For
differential
mode:
Connect a SCSI cable from the back panel
at
the la-
bel "Singled-Ended" to the
SCSI devices (see "Cable Specifications").
The total of the internal·and external cable lengths
must
not
exceed
80
feet. See Figure 3-10.

2 Terminate the
physical
ends of the SCSI bus
by
terminating
the
last SCSI
device
with
on-board termination (see manufacturer's documentation)
or
by
using
an
external terminator.
Be
sure devices
in
the middle
of
the
SCSI
bus
are
not
