Determining
the
test
method:
There
are
two
shorts
test
procedures
you
can
use
depending
on
the
test
hardware
you
have.
-
Use
a
new
capacitor
book
and
the
LGA
shorts
tester
For
this
method,
use
the
new
capacitor
book
(part
44P2471),
or
any
follow-on
with
the
necessary
LGA
test
support
features,
and
the
new
LGA
shorts
tester
(LGA-ST)
(part
44P4107).
-
Use
a
multimeter
and
capacitor
book
There
are
two
methods
covered
here:
v
Use
a
multimeter
and
a
new
capacitor
book
For
this
method,
use
a
hand
held
multimeter
and
capacitor
book
(44P2471),
or
any
follow-on
capacitor
books
with
the
necessary
LGA
test
support
features.
Or:
v
Use
a
multimeter,
the
original
capacitor
book,
and
the
MCM/L3
module
short-circuit
test
tool.
This
is
the
least
accurate
method
and
should
only
be
used
when
no
other
options
are
available.
For
this
method,
use
a
hand
held
multimeter,
the
original
capacitor
book
(part
11P1540),
and
the
MCM/L3
module
short-circuit
test
tool
(part
44P0209).
Test
method

:
Testing
MCM
and
passthru
modules
for
a
short
circuit
using
a
new
capacitor
book
and
automated
shorts
tester:
There
are
three
procedures
that
are
covered
in
this
topic:

Test
method
1:
Testing
for
proper
operation
of
LGA-ST
and
LGA-ST
Battery
1.
Plug
the
LGA-ST
test
head
into
the
9
pin
female
D-Shell
located
on
the
LGA-ST
control
box.
2.
Perform
the
procedure
defined
in
the
table
below
to
ensure
that
the
LGA-ST
battery
is
good,
and
that
the
LGA-ST
is
functioning
properly
to
detect
shorts.

2.
If

2.
If

then
the
LGA-ST
is

Replace
it
before

3.
Disengage
all
DCAs
from
the
backplane.
4.
Plug
the
LGA-ST
test
box
into
the
capacitor
book
9

D-shell.
5.
Test
the
LGA-ST
for
the
ability
to
detect
passing
conditions
using
the
following
table.
