Installing
the
modems
on
the
switch
Note:
You
should
set
up
the
modems
before
you
power
on
the
switch
and
connect
it
to
the
fabric.
The
switch
detects
modems
only
during
power
on,
restart,
or
CP
card
failover.
Set
up
the
modems
before
you
connect
the
switch
to
the
fabric.
You
need
the
following
items
to
set
up
two
modems
to
work
with
the
switch:
v
Two
Hayes-compatible
modems,
such
as
the
Zoom/Modem
V.92
EXT
Model
3049
v
Two
standard
modem
cables,
DB25
(male)
to
DB9
(female)
v
One
RJ–11
Y
adapter
for
standard
Telco
wiring
or
equivalent
circuitry
(a
total
of
three
connections)
v
One
analog
telephone
line
CAUTION:
For
normal
installation,
the
switch
and
attached
modems
are
powered
off
before
cabling
them.
The
modems
are
automatically
detected
during
a
power-on
sequence.
Perform
the
following
steps
to
install
the
modems:
1.
Verify
that
the
power
to
the
switch
is
off.
2.
Set
up
the
two
modem
units
and
the
required
power
connections.
Do
not
turn
on
the
power
to
the
modems
until
all
cables
are
attached.
3.
Connect
the
modem
cables
to
the
modems
and
to
the
switch
modem
ports.
See
4.
Connect
the
telephone
line
inputs
on
the
modems
to
the
RJ–11
Y
adapter.
This
effectively
places
both
modems
on
a
single
telephone
line.
