Advanced
System
Management
Test
The
Advanced
System
Management
(ASM)
Test
consists
of
the
following
sub-tests:
v
ASM/ISMP
I2C
Bus
Test
This
test
queries
the
status
of
the
I2C
subsystem
within
the
x450
node.
It
reports
back
on
any
internal
integrated
circuit
(I2C)
radials
that
either
are
untested
or
tested
bad.
v
ASM
Built-In
Self
Test
(BIST)
This
test
queries
the
ASM
for
the
status
of
its
last-run
BIST.
Non-disruptive
portions
of
BIST
are
run
periodically
on
the
ASM
adapter.
Failing
BIST
results
will
be
reported
so
that
you
can
determine
which,
if
any,
of
the
major
subsystems
of
the
ASM
adapter
are
malfunctioning.
v
ASM
Restart
Test
Use
this
test
to
restart
the
ASM
adapter
without
disconnecting
ac
power
from
the
xSeries
450
server.
v
RXE
I2C
Bus
Test
This
test
queries
the
status
of
the
I2C
subsystem
within
attached
RXE-100
units.
It
reports
back
on
any
I2C
radials
that
are
either
untested
or
tested
bad.
Note:
To
run
this
test,
the
ASM
adapter
must
be
cabled
correctly
to
the
RXE-100
unit
using
the
RS-485
bus
and
appropriate
Category
3
and
Category
5
cables
with
proper
termination.
v
RXE
ISMP
Self
Test
This
test
queries
the
ISMP
controllers
of
attached
RXE-100
units
for
the
last
BIST
status.
Failing
RXE-100
BIST
results
will
be
reported
so
that
you
can
determine
if
the
ISMP
subsystem
is
malfunctioning
due
to
microcontroller
problems.
Note:
To
run
this
test,
the
ASM
adapter
must
be
cabled
correctly
to
the
RXE-100
unit
using
the
RS-485
bus
and
appropriate
Category
3
and
Category
5
cables
with
proper
termination.
