FRU
Identify

This
system
is
configured
with
an
arrangement
of
LEDs
that
help
identify
various
components
of
the
system.
These
include,

are
not

of
the
hierarchy,
followed
by
the

and
the

to
locate

Any
identify

in
the
system
may
be
flashed
(when
the
processor
subsystem
is
in
the
failed

and
power
is

Any
identify
LED
in
the
system
can
also
be
flashed
by
using
the
Identify

may
be
booted
to

prompt
and
the
command
FRU-LED-MENU
entered.
A

displays
that
allows
you
to
enable
the
desired

See
for
instructions
on
setting
up

to
enable
the

v
If
the
system
is
logically
partitioned,
the
HMC
must
be
attached.
You
can
use
the
HMC
to
enable
any
FRU

LED
to
be
flashed.
