Press
the
toggle
switch
on
the
LGA-ST
forward
to
the
MCM/L3
PWR/GND
position.
This
action
will
test
the
L3
modules
for
power-to-ground
shorts.
Observe
the
lit
LEDs
on
the
LGA-ST
and
take
the
corresponding
following
actions:
Green
L3
LED
is
lit
This
is
a
pass
state.
No
further
action
is
required.
Amber
L3
LED
is
lit
This
is
a
fail
state.
There
might
be
a
short
between
one
of
the
two
L3
voltages
and
ground,
which
is
a
failing
condition,
or
the
combination
of
memory
books,
I/O
books,
and
L3
cache
modules
in
parallel
might
be
creating
a
low
resistance.
Complete
the
following
steps
to
correct
this
condition:
a.
Disengage
memory
books
followed
by
I/O
books
one
at
a
time.
b.
Repeat
step
through
step
until
either
the
L3
test
results
in
a
pass
state,
or
all
memory
and
I/O
are
disengaged
and
the
L3
test
remains
in
a
fail
state.
c.
If
the
L3
module
test
remains
in
a
fail
state
after
all
memory
and
I/O
are
disengaged,
remove
the
L3
module
and
inspect
the
interposer
for
shorts.
d.
Reinstall
the
L3
module
once
and
repeat
the
test.
If
the
fail
persists,
replace
the
L3
module.
Green
MCM
LED
is
lit
This
is
a
pass
state.
No
further
action
is
required.
Amber
MCM
LED
is
lit
This
is
a
fail
state.
There
might
be
a
short
across
the
MCM
voltage
and
ground.
Perform
the
and
correct
any
short
conditions
before
powering
on.
5.
Place
the
toggle
switch
into
the
L3
PWR/PWR
position.
Green
and
Amber
MEM
LEDs
are
not
lit
Power
is
removed
from
these
circuits
when
the
switch
is
in
the
L3
PWR/PWR
position.
Green
L3
LED
is
lit
This
is
a
pass
state.
No
further
action
is
required.
Amber
L3
LED
is
lit
This
is
a
fail
state.
There
is
a
short
between
the
two
L3
power
domains.
Complete
the
following
steps
to
correct
this
condition:
a.
Remove
the
L3
module
and
inspect
the
interposer
for
shorts.
b.
Reinstall
the
L3
module
once
and
repeat
the
test.
If
the
fail
condition
persists,
replace
the
L3
module.
6.
Install
another
L3
module
and
repeat
step
through
step
until
all
required
L3
modules
