Repeating long beeps Indicates that a memory error has occurred. Ensure that all DIMMs are correctly installed. One long beep and two short beeps Indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. Ensure that the video adapter is correctly installed. For a list of POST errors, see "POST error messages" on page 95. Small computer system interface messages (some models) The following table lists actions to take if you receive a SCSI error message. Note: If the server does not have a SCSI hard disk drive, ignore any message that indicates that the BIOS is not installed. You will get these messages only when running the SCSI Select Utility. Table 2. SCSI messages SCSI Messages Description All One or more of the following might be causing the problem. v A failing SCSI device (adapter or drive) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain v An improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable Action: Verify that: v The external SCSI devices are turned on. External SCSI devices must be turned on before the server. v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated properly. v The SCSI devices are configured correctly. If the above items are correct, run the diagnostic programs to obtain additional information about the failing device. Diagnostic programs and error messages The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs provide the primary methods of testing the major components of the server. Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel. 10 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

Indicates
that
a
memory
error
has
occurred.
Ensure
that
all
DIMMs
are
correctly
installed.
One

cannot
initialize
the
video
screen
to
display
any
additional
information.
Ensure
that
the

models)
The
following
table
lists
actions
to
take
if
you
receive
a
SCSI
error
message.
Note:
If
the
server
does
not
have
a
SCSI
hard
disk
drive,
ignore
any
message
that
indicates
that
the

messages
SCSI
Messages
Description
All
One
or
more
of
the
following
might
be
causing
the
problem.

or
drive)
v
An
improper
SCSI
configuration
v
Duplicate
SCSI
IDs
in
the
same
SCSI
chain
v

improperly
installed
SCSI
terminator
v
A
defective
SCSI
terminator
v
An
improperly
installed
cable
v
A
defective
cable
Action:
Verify
that:
v
The
external
SCSI
devices
are
turned
on.
External
SCSI
devices
must
be
turned
on
before
the
server.
v
The
cables
for
all
external
SCSI
devices
are
connected
correctly.
v
The
last
device
in
each
SCSI
chain
is
terminated
properly.
v
The
SCSI
devices
are
configured
correctly.
If
the
above
items
are
correct,
run
the
diagnostic
programs
to
obtain
additional
information
about
the
failing
device.
Diagnostic
programs
and
error
messages
The
server
diagnostic
programs
are
stored
on
the
IBM
Enhanced
Diagnostics
CD
.
These
programs
provide
the
primary
methods
of
testing
the
major
components
of
the
server.
Diagnostic
error
messages
indicate
that
a
problem
exists;
they
are
not
intended
to
be
used
to
identify
a
failing
part.
Troubleshooting
and
servicing
of
complex
problems
that
are
indicated
by
error
messages
should
be
performed
by
trained
service
personnel.
