Mode
indicator
The
mode
indicator
provides
status
information
on
the
2145
uninterruptible
power
supply
(2145
UPS)
and
is
located
on
the
front
panel.
When
the
mode
indicator
is
a
steady
green,
the
2145
UPS
is
in
normal
mode.
The
2145
UPS
checks
and
charges
its
battery
as
necessary.
When
the
mode
indicator
is
flashing
green,
the
2145
UPS
is
in
standby
mode.
Standby
mode
means
that
the
2145
UPS
is
turned
off
but
is
still
connected
to
the
main
power
source.
No
power
is
available
from
the
2145
UPS
output
sockets
but
the
2145
UPS
monitors
and
charges
its
battery
as
necessary.
When
the
mode
indicator
is
steady
red,
the
2145
UPS
is
in
bypass
mode
because
of
one
of
the
following
conditions:
v
The
2145
UPS
has
overheated
v
The
2145
UPS
has
an
overload
condition
of
103%
through
110%
for
30
seconds
v
The
2145
UPS
detects
a
fault
in
the
battery
or
in
the
2145
UPS
electronics
assembly
When
the
mode
indicator
is
flashing
red
and
the
alarm
is
sounding,
the
voltage
range
setting
might
not
be
correct.
When
a
SAN
Volume
Controller
2145-4F2
is
connected
to
the
2145
UPS,
the
SAN
Volume
Controller
2145-4F2
automatically
adjusts
the
voltage
range
setting.
Take
no
action
for
this
alarm
condition
unless
it
persists
for
more
than
five
minutes
after
a
SAN
Volume
Controller
2145-4F2
has
been
connected
to
a
2145
UPS
and
powered
on.

press
it
at
any
other
time,
