If you cannot find the problem using the diagnostic programs, see "Solving undetermined problems" on page 80 for information about testing the blade workstation. Running the diagnostic programs To run the diagnostic programs, complete the following steps: 1. If the blade workstation is running, turn off the blade workstation. 2. Turn on the blade workstation. 3. When the prompt F2 for Diagnostics appears, press F2. 4. From the top of the screen, select either Extended or Basic. 5. From the menu, select the test that you want to run, and follow the instructions on the screen. For help with the diagnostic programs, press F1. You also can press F1 from within a help screen to obtain online documentation from which you can select different categories. To exit from the help information, press Esc. To determine what action you should take as a result of a diagnostic text message or error code, see the table in "Diagnostic error codes" on page 71. If the diagnostic programs do not detect any hardware errors but the problem remains during normal server operations, a software error might be the cause. If you suspect a software problem, see the information that comes with your software. A single problem might cause more than one error message. When this happens, correct the cause of the first error message. The other error messages usually will not occur the next time you run the diagnostic programs. Exception: If there are multiple error codes that indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See "Microprocessor problems" on page 59 for information about diagnosing microprocessor problems. If the blade workstation stops responding during testing and you cannot continue, restart the blade workstation and try running the diagnostic programs again. If the problem remains, replace the component that was being tested when the blade workstation stopped. The diagnostic programs assume that a keyboard and mouse are attached to the BladeCenter unit and that the blade workstation controls them. If you run the diagnostic programs with either no mouse or a mouse attached to the BladeCenter unit that is not controlled by the blade workstation, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys. To view server configuration information such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, or device drivers, select Hardware Info from the top of the screen.

If
you
cannot
find
the
problem
using
the
diagnostic
programs,
see
“Solving
undetermined
problems”
on
page
80
for
information
about
testing
the
blade
workstation.
Running
the
diagnostic
programs
To
run
the
diagnostic
programs,
complete
the
following
steps:
1.
If
the
blade
workstation
is
running,
turn
off
the
blade
workstation.
2.
Turn
on
the
blade
workstation.
3.
When
the
prompt
F2
for
Diagnostics
appears,
press
F2.
4.
From
the
top
of
the
screen,
select
either
Extended
or
Basic
.
5.
From
the
menu,
select
the
test
that
you
want
to
run,
and
follow
the
instructions
on
the
screen.
For
help
with
the
diagnostic
programs,
press
F1.
You
also
can
press
F1
from
within
a
help
screen
to
obtain
online
documentation
from
which
you
can
select
different
categories.
To
exit
from
the
help
information,
press
Esc.
To
determine
what
action
you
should
take
as
a
result
of
a
diagnostic
text
message
or
error
code,
see
the
table
in
“Diagnostic
error
codes”
on
page
71.
If
the
diagnostic
programs
do
not
detect
any
hardware
errors
but
the
problem
remains
during
normal
server
operations,
a
software
error
might
be
the
cause.
If
you
suspect
a
software
problem,
see
the
information
that
comes
with
your
software.
A
single
problem
might
cause
more
than
one
error
message.
When
this
happens,
correct
the
cause
of
the
first
error
message.
The
other
error
messages
usually
will
not
occur
the
next
time
you
run
the
diagnostic
programs.
Exception:
If
there
are
multiple
error
codes
that
indicate
a
microprocessor
error,
the
error
might
be
in
a
microprocessor
or
in
a
microprocessor
socket.
See
“Microprocessor
problems”
on
page
59
for
information
about
diagnosing
microprocessor
problems.
If
the
blade
workstation
stops
responding
during
testing
and
you
cannot
continue,
restart
the
blade
workstation
and
try
running
the
diagnostic
programs
again.
If
the
problem
remains,
replace
the
component
that
was
being
tested
when
the
blade
workstation
stopped.
The
diagnostic
programs
assume
that
a
keyboard
and
mouse
are
attached
to
the
BladeCenter
unit
and
that
the
blade
workstation
controls
them.
If
you
run
the
diagnostic
programs
with
either
no
mouse
or
a
mouse
attached
to
the
BladeCenter
unit
that
is
not
controlled
by
the
blade
workstation,
you
cannot
use
the
Next
Cat
and
Prev
Cat
buttons
to
select
categories.
All
other
mouse-selectable
functions
are
available
through
function
keys.
To
view
server
configuration
information
such
as
system
configuration,
memory
contents,
interrupt
request
(IRQ)
use,
direct
memory
access
(DMA)
use,
or
device
drivers,
select
Hardware
Info
from
the
top
of
the
screen.
