Notes: 1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms. 2. For IBM devices not supported by this index, refer to the manual for that device. 3. Always start with "General checkout" on page 21. The symptom-to-FRU index lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this symptom-to-FRU index to help you decide which FRUs to have available when servicing the computer. The first column of the two-column tables in this index lists error codes or messages, and the second column lists one or more suggested actions or FRUs to replace. Take the action (or replace the FRU) suggested first in the list of the second column, then try the server again to see if the problem has been corrected. Note: Try reseating a suspected component or reconnecting a cable before replacing the component. The POST BIOS code displays POST error codes and messages on the screen. © Copyright IBM Corp. 2002 85

This
index
supports
xSeries
205
servers.
Notes:
1.
Check
the
configuration
before
you
replace
a
FRU.
Configuration
problems
can
cause
false
errors
and
symptoms.
2.
For
IBM
devices
not
supported
by
this
index,
refer
to
the
manual
for
that
device.
3.
Always
start
with
“General
checkout”
on
page
21.
The
symptom-to-FRU
index
lists
symptoms,
errors,
and
the
possible
causes.
The
most
likely
cause
is
listed
first.
Use
this
symptom-to-FRU
index
to
help
you
decide
which
FRUs
to
have
available
when
servicing
the
computer.
The
first
column
of
the
two-column
tables
in
this
index
lists
error
codes
or
messages,
and
the
second
column
lists
one
or
more
suggested
actions
or
FRUs
to
replace.
Take
the
action
(or
replace
the
FRU)
suggested
first
in
the
list
of
the
second
column,
then
try
the
server
again
to
see
if
the
problem
has
been
corrected.
Note:
Try
reseating
a
suspected
component
or
reconnecting
a
cable
before
replacing
the
component.
The
POST
BIOS
code
displays
POST
error
codes
and
messages
on
the
screen.
