Load-level
indicators
The
load-level
indicators
show
the
percentage
of
the
2145
uninterruptible
power
supply
(2145
UPS)
capacity
that
the
SAN
Volume
Controller
2145-4F2
is
using.
When
all
the
indicators
are
lit,
the
power
requirements
of
the
SAN
Volume
Controller
2145-4F2
have
exceeded
the
capacity
of
the
2145
UPS.
Site
wiring
fault
indicator
The
site
wiring
fault
indicator
on
the
2145
uninterruptible
power
supply
(2145
UPS)
shows
that
either
a
ground
wire
connection
does
not
exist
or
the
live
and
neutral
wires
are
reversed
in
the
input
power
connection.
The
site
wiring
fault
indicator
is
located
on
the
front
panel
of
the
2145
UPS.
Battery
service
indicator
The
battery
service
indicator
is
located
on
the
front
panel
of
the
2145
uninterruptible
power
supply
(2145
UPS)
and
shows
that
the
charge
in
the
battery
has
become
low
while
the
2145
UPS
is
in
battery
mode.
The
alarm
continues
to
beep
once
every
five
seconds.
The
application
programs
immediately
complete
and
save
the
work
to
prevent
loss
of
data.
If
the
2145
UPS
shuts
down,
it
automatically
restarts
when
the
main
power
returns.
Battery
mode
indicator
The
battery
mode
indicator
shows
that
the
2145
uninterruptible
power
supply
(2145
UPS)
is
operating
on
batteries.
The
battery
mode
indicator
lights
up
when
the
main
power
source
fails
and
the
2145
UPS
is
running
on
battery
power.
The
alarm
beeps
once
every
five
seconds.
When
main
power
returns,
the
2145
UPS
returns
to
normal
mode
and
the
battery
recharges.
The
battery
mode
indicator
then
shuts
off
and
the
alarm
ceases.
General
alarm
indicator
The
general
alarm
indicator
on
the
2145
uninterruptible
power
supply
(2145
UPS)
turns
on
when
a
power
or
temperature
problem
occurs.
When
the
general
alarm
indicator
is
accompanied
by
the
audio
alarm
beeping
every
five
seconds,
the
battery
is
low.
If
the
audio
alarm
is
continuous,
the
internal
temperature
of
the
2145
UPS
is
too
high
or
there
has
been
a
momentary
output
overload.
