Preparing
Network
Connections
Token
Ring Connection
Equipment
The
term
Token Ring
refers
to
both
IBMs
Token
Ring
Network
which
IBM
developed
in the
1970s
and
to
IEEE
802.5
networks
The
IEEE
802.5
specification
was
modeled
after
and
still
closely
shadows
IBMs
network
The
two
types
are
compatible
although
the
specifications
differ
slightly
You
will
need
an 802.5
MAU
or
multistation
access
unit
MSAU
to
provide
the interface
between
the
TRIP
Token
Ring
interfaces
and
the external
ring
and
Token
Ring
lobe
cable
between
each
TRIP
port
and
the
MAU
or
MSAU
Lobe
cables
connect
each
Token
Ring
station
TRIP
port
to
the
MAU
or
MSAU
and
patch
cables
can
connect
adjacent
MSAUs
to
form one
large ring
Before
you
enable
the
Token
Ring
interfaces
ensure
that
each
is
set
for the correct
speed
or
it
can
bring
down
the ring
TRIP
ports operate
at
either
or
16Mbps
The
default
speed
for
all
TRIP
ports
is
Mbps
which
you
can
change
to
16
Mbps
on any
port
with
the configuration
command
ring-speed
where
is
the speed
or
16
in
Mbps
The
speed
of each
Token
Ring
port
must match
the speed
of the ring
to
which
it
is
connected
Caution
Each
TRIP
port
must be
configured
for the
same
ring speed
as
the ring
to
which
it
is
connected
either
or 16
Mbps
If
the port
is set
for
different
speed
it
will
cause
the ring to
beacon
which
effectively
brings
the ring
down
and makes
it
inoperable
Token
Ring Cables
and Connectors
The
Token
Ring
ports
on
the
TRIP
are
DB-9
PC
type
receptacles
that
require
Type
or
Type
lobe
cables
Type
lobe
cables
use
shielded
twisted
pair cable
and
terminate
at
the
network
end
with
large
MAU
plug
