Configuring
Cards
Configurüng
Cards
Some
cards can be configured
for different
user applications
For example
the
CSC-MCI
card has
jumpers
that
allow
you to
change from data terminal equipment
DTE
mode
to
data
communications
equipment
DCE
mode
depending upon
your requirements
In addition
most
Multibus cards
have
card-numbering
switches
that
allow
you to reconfigure
them
for
different slot
positions in
the chassis
Included
in this
section
is
an illustration
of each card
and
tables
showing
its
configurable
jumpers
and
switches
Following is listing
of
all the configurable
cards
in
the chassis Cards excluded
from
this
list are
not configurable
through
hardware
alterations
Processor
cards
CSC/3 and CSCI4
CSC-MCI
and
CSC-SCI
CSC-MEC
and
CSC-C2MEC
CSC-1R
and
CSC-2R
CSC-R16M
Card-Nlfmbering
Fundamentas
Most Multibus
interface
cards require
that
unique
card
numbers
be assigned
to
them
before the
entire
system
becomes
operational
Cards
that
are
installed in
the chassis are correctly
numbered
before
shipment
but
you
may
have
to
renumber them
when
you
order
and
install
new
or additional
cards
These
card
numbers
are position markers
for the
system
software
that let the
system
know
what
cards are
installed in
what
slots
The
card
numbers
are assigned
by way
of dual
in-line package
DIP
switch located
on
the component
side
of the
card These
switches
are
set
so that
each card has
unique
card
number
In general each card
number should
be
unique
within the
set
of
all
cards
installed in
the chassis Exceptions
to this
are
the
ENVM
and
processor
cards
which have
no
switches
and
are always installed
in the
same two
slots
the
top
slot
and
the second
slot
from
the top
respectively
Note
If
ciscoBus controller card
is
used
in the chassis
no Multibus interface cards can be
numbered
as
Card The Card
designation
is
reserved
for
the ciscoBus
controller
card by default
