Chapter 6. Symptom-to-FRU index Use this index to aid in locating failing or failed components in the HS40 Type 8839 blade server. 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 "Checkout procedure" on page 21. The symptom-to-FRU index lists symptoms, errors, and the possible causes of common failures. 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 server. The left column of the tables in this index lists error codes or messages, and the right column lists one or more suggested actions or FRUs to replace. Note: In tables with more than two columns, multiple columns are required to describe the error symptoms. Take the action (or replace the FRU) suggested first in the list of the right column, then restart the server to see if the problem has been corrected before taking further action. Note: Reseat a suspected component or reconnect a cable before replacing the component. POST error codes and messages are displayed on the screen and in the management-module error log. Beep codes Beep symptoms are short tones or a series of short tones separated by pauses that indicate system-error conditions. Both the system BIOS and the baseboard management controller (BMC) emit beep codes (see the following two sections). BIOS-generated beep codes The following table lists the POST error beep codes. Typically, prior to system video initialization, the BIOS uses these beep codes to inform users of error conditions. Note: See Chapter 7, "Parts listing, Type 8839," on page 105 to determine which components should be replaced by a field service technician.

Chapter

Symptom-to-FRU
index
Use
this
index
to
aid
in
locating
failing
or
failed
components
in
the
HS40
Type
8839
blade
server.
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
“Checkout
procedure”
on
page
21.
The
symptom-to-FRU
index
lists
symptoms,
errors,
and
the
possible
causes
of
common
failures.
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
server.
The
left
column
of
the
tables
in
this
index
lists
error
codes
or
messages,
and
the
right
column
lists
one
or
more
suggested
actions
or
FRUs
to
replace.
Note:
In
tables
with
more
than
two
columns,
multiple
columns
are
required
to
describe
the
error
symptoms.
Take
the
action
(or
replace
the
FRU)
suggested
first
in
the
list
of
the
right
column,
then
restart
the
server
to
see
if
the
problem
has
been
corrected
before
taking
further
action.
Note:
Reseat
a
suspected
component
or
reconnect
a
cable
before
replacing
the
component.
POST
error
codes
and
messages
are
displayed
on
the
screen
and
in
the
management-module
error
log.
Beep
codes
Beep
symptoms
are
short
tones
or
a
series
of
short
tones
separated
by
pauses
that
indicate
system-error
conditions.
Both
the
system
BIOS
and
the
baseboard
management
controller
(BMC)
emit
beep
codes
(see
the
following
two
sections).
BIOS-generated
beep
codes
The
following
table
lists
the
POST
error
beep
codes.
Typically,
prior
to
system
video
initialization,
the
BIOS
uses
these
beep
codes
to
inform
users
of
error
conditions.
Note:
See
Chapter
7,
“Parts
listing,
Type
8839,”
on
page
105
to
determine
which
components
should
be
replaced
by
a
field
service
technician.
