2.
GENERAL
2.01
Once
the
FD-2240A
is
in
operation,
no
attention
is
required.
If
a
unit
fails,
the
equipment
will
automatically
issue
the
appropriate
alarm
indications.
If
the
equipment
has
a
redundant
configuration,
the
FD-2240A
automatic
switching
system
will
automatically
place
the
redundant
unit(s)
online.
If
the
equipment
is
nonredundant,
automatic
switching
function
is
not
available.
2.02
After
automatic
switching
occurs,
the
faulty
unit
can
be
replaced
without
interrupting
service.
It
is
not
necessary
to
repeat
the
starting
procedure
after
the
unit
is
replaced.
The
equipment
continues
to
operate
in
online
mode
with
the
newly
installed
unit
acting
as
the
redundant
standby.
2.03
Manual
control
of
the
FD-2240A
is
usually
necessary
only
during
equipment
maintenance.
Refer
to
NECA
365-407-500
for
detailed
maintenance
instruc-
tions
and
procedures.
3.
CONTROLS
AND
INDICATORS
3.01
Refer
to
Figure
3-i
for
unit
locations.
Figures
3-2
through
3-10
show
the
controls
and
indicators
utilized
during
operation
and
testing
of
the
FD-2240A
and
describes
the
function
of
each.
All
controls
and
indicators
are
located
on
the
front
of
the
plug-in
units.
