Identifying
Startup
Problems
When
you
start
up
the
system by
turning
on
the
main
system
power
switch
on
the interface
processor
end
of the
power
supplies
the following
should
occur
The
AC
or
DC
OK
LED
should
go on immediately
and
it
should
remain on
as
long
as
the
system
is
receiving
source
power
and
the
power
switch
is
in the
on
position
If this
LED
does
not
go
on
or
if
it
goes
off while
the
power
switch
is
still
on
there could
be
problem
with
either
the source
power
the
internal
DC
power
that
the
power
supplies
distribute
to
the
internal
components
or the cooling
subsystem
The
green
AC
or
DC
OK
LED
indicates
the
status
of the
power
supplies
and
internal
DC
voltages
The
AC
or
DC
OK
LED
stays
on
when
all
of the following
conditions
are
met
Power
supplies
are
on and
receiving
100
to
240
VAC
50
to
60
Hz or
48VDC
to
6OVDC
source
power
Power
supplies
are providing
the
12 12
and
24
VDC
to
internal
components
All
internal
DC
voltages
are
within
tolerance
If
the
AC
or
DC
source
power
or
any
of the
internal
DC
voltages
exceed
allowable
tolerances
the
AC
or
DC
OK
LED
will
not
go
on
or will go off shortly
after
you
turn
on
the
power
Because
both
the
RSP2
which
uses
12
12
VDC
and
the
blower module
which
uses
24
VDC
are required
for operation
problem
with
any
of the
internal
DC
lines
can
prevent
the
system
from
starting
up
or continuing
operation
For example
if
there
is
problem
with
the
24
VDC
line
that
supplies
the
blower
module
the
system
will
start
up
but
also recognize
that
the
blower
is
not
operating
The
system
will
initiate
blower
failure
shutdown
sequence
display
the appropriate
warning messages
then
shut
down
after
two minutes
If
there
is
problem
with
any
of the other
DC
lines
the
RSP2
will not be
able
to
initialize
the
system
software
so the
system might
attempt
to
start
up
and
fail
during
the boot
sequence
Depending
upon
when
the
DC OK
LED
goes
off
proceed
as
follows
If
the
AC
or
DC
OK
LED
stays
off
if
it
never
goes
on
when
you
turn
on
the
power
switch
there
is
problem
with
either
the
AC
or
DC
source
power
or the
DC
power
that
is
distributed
to
the internal
components
Proceed
to
the section
Troubleshooting
the
Power
Subsystem
in
this
chapter
If
the
AC
or
DC
OK
LED
goes
on
temporarily
then
goes
off within
30 seconds
the
system
is
most
likely
shutting
itself
down
because
it
detected
an out-of-tolerance
power
or
temperature
condition
within
the
power
supplies
Proceed
to
the section
Troubleshooting
the
Power
Subsystem
in
this
chapter
If
the
AC
or
DC
OK
LED
goes
on
and
the system
starts
up
as
expected
but
then
displays
the following
message
and
shuts
down
after
two minutes
there
is
problem
with
the
blower
Proceed
to
the section
Troubleshooting
the Cooling
Subsystem
in
this
chapter
%ENVN-2-FAN
Fan
has
failed
shutdown
in
minutes
if
the
AC
or
DC
OK
LED
stays
off yet the system
starts
up
correctly
displays
the preceding
message
and
shuts
down
after
about
two
minutes
there
is
problem
with
the
24VDC
line
to
the
blower
module
