Front Panel Operation

5–9
Restore
Holdoff
is
the
length
of
time
that
the
originally
faulted
modem
must
stay
unfaulted
before
the
Switch
will
automatically
put
it
back
online.
Both
holdoffs
can
be
set
from
1
to
99
seconds.
5.2.2.4 (CONFIG:) MASKS
ALARM MASK: MODEM-ALARMS
SW-ALARMS AUDIO (ENTER)
The
Switch
logs
and
reacts
to
both
its
switch
faults
and
modem
faults.
Mask
either
type
of
fault
using
this
submenu.
In
addition,
use
this
submenu
to
enable
a
buzzer
as
an
audible
indicator.
5.2.2.4.1
(CONFIG: MASKS)
Æ
MODEM ALARM MASK
MODEM ALARM MASK: NONE
TX RX (ENTER)
Select
TX
or
RX
to
mask
the
pertinent
traffic
faults
from
being
reacted
to
by
the
Switch.
This
not
only
prevents
the
Switch
from
performing
Auto
Mode
functions
when
these
modem
faults
are
sensed,
but
also
keeps
the
faults
from
being
logged
by
the
Switch.
Note
that
these
selections
are
global
to
all
the
modems.
If
masking
of
individual
modem
faults
is
desired,
it
should
be
done
directly
on
the
modem.
Unmasked
modem
faults
are
logged
on
active
modems
only.
5.2.2.4.2
(CONFIG: MASKS)
Æ
SWITCH ALARM MASK
SWITCH ALARM MASK: NONE
É
PSU-A
Ë
PSU-B (ENTER)
Select
which,
if
either,
of
the
plug
‐
in
power
supply
units
should
be
ignored
in
case
any
of
their
voltage
outputs
are
monitored
by
the
Switch
as
being
out
of
range.
Press
ENTER
when
done.
You
can
mask
only
one
unit
at
a
time.
Normally
this
is
done
if
you
choose
to
run
with
only
one
supply,
or
if
a
bad
supply
has
been
removed
for
service
or
replacement.
5.2.2.4.3
(CONFIG: MASKS)
Æ
AUDIO MASK
AUDIO MASK: NONE SW-ALMS
MODEM-ALMS BOTH (ENT)
For
all
Switch
or
modem
alarms
that
are
unmasked,
you
may
select
which
alarm
types
should
force
the
Switch
to
react
with
an
audible
buzzer
located
behind
the
front
panel.
In
addition,
a
relay
closure
to
ground
activates
on
pin
20
of
the
System
Alarms
connector
so
that
you
may
attach
other
indicators.
