The
AMIDiag
program
is
the
primary
method
of
testing
the
major
components
of
the
server.
The
AMIDiag
program
is
stored
in
the
EEPROM
on
the
I/O
board.
You
can
download
the
latest
version
of
this
program
and
copy
it
to
a
CD
so
that
you
can
update
the
AMIDiag
program.
See

The
diagnostic
program
for
the
Ethernet
controller
is
on
the
Resource

When
you
turn
on
the
server,
it
performs
a
series
of
tests
to
check
the
operation
of
server
components
and
some
of
the
options
installed
in
the
server.
This
series
of
tests
is
called
the
power-on
self-test,
or
POST.
Notes:
1.
This
server
does
not
produce
beep
codes.
2.
Depending
on
system
configuration,
POST
might
run
for
several
minutes
before
the
video
console
is
enabled.
During
this
time,
POST
operation
is
indicated
by
the
flashing
blue
locator
LED
on
the
front
panel.
Diagnostic
display
error

track
the
startup
progress
until
video
is
enabled.
If
POST
finishes
without
detecting
any
problems,
the
EFI
Boot
Manager
screen
appears.
If
POST
detects
a
problem,
an
error
message
will
be
sent
to
either
the
serial
port
or
the
display
screen.
