v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 7996," on page 11 to determine which components are CRUs and which components are FRUs. v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Error code Description Action 405-xxx-000 Failed Ethernet test on controller on the system board. 1. Make sure that Ethernet is not disabled in the Configuration/Setup Utility program. 2. (Trained service technician only) Replace the system board assembly. Recovering from a BIOS update failure The blade workstation has an advanced recovery feature that will automatically switch to a backup BIOS page if the BIOS code in the blade workstation has become damaged, such as from a power failure during an update. The flash memory of the blade workstation consists of a primary page and a backup page. If the BIOS code in the primary page is damaged, the baseboard management controller will detect the error and automatically switch to the backup page to start the blade workstation. If this happens, a POST message Booted from backup POST/BIOS image is displayed. The backup page version may not be the same version as the primary image. You can then recover or restore the original primary page BIOS by using a BIOS flash diskette. To recover the BIOS code and restore the blade workstation operation to the primary page, complete the following steps: 1. Download the latest version of the BIOS code from http://www.ibm.com/ bladecenter/. 2. Update the BIOS code, following the instructions that come with the update file that you downloaded. This will automatically restore and update the primary page. 3. Restart the blade workstation. If that procedure fails, the blade workstation might not restart correctly or might not display video. To manually restore the BIOS code, complete the following steps: 1. Read the safety information that begins on page vii and "Installation guidelines" on page 13. 2. Turn off the blade workstation. 3. Remove the blade workstation from the BladeCenter unit (see "Removing the blade workstation from a BladeCenter unit" on page 16). 4. Remove the cover (see "Removing the blade workstation cover" on page 19). 5. Locate the BIOS recovery jumper on the system board (see "System board jumpers and buttons" on page 7). 6. Move the BIOS recovery jumper to the Closed position to enable the recovery mode. 7. Replace the cover and reinstall the blade workstation in the BladeCenter unit, making sure that the media tray is selected by the relevant blade workstation. 74 BladeCenter HC10 Type 7996: Problem Determination and Service Guide

Recovering
from
a
BIOS
update
failure
The
blade
workstation
has
an
advanced
recovery
feature
that
will
automatically
switch
to
a
backup
BIOS
page
if
the
BIOS
code
in
the
blade
workstation
has
become
damaged,
such
as
from
a
power
failure
during
an
update.
The
flash
memory
of
the
blade
workstation
consists
of
a
primary
page
and
a
backup
page.
If
the
BIOS
code
in
the
primary
page
is
damaged,
the
baseboard
management
controller
will
detect
the
error
and
automatically
switch
to
the
backup
page
to
start
the
blade
workstation.
If
this
happens,
a
POST
message
Booted
from

is
displayed.
The
backup
page
version
may
not
be
the
same

as
the
primary
image.
You
can
then
recover
or
restore
the
original
primary

BIOS
by
using
a
BIOS
flash
diskette.
To
recover
the
BIOS
code
and
restore
the
blade
workstation
operation
to
the
primary
page,
complete
the
following
steps:
1.
Download
the
latest
version
of
the
BIOS
code
from
bladecenter/.
2.
Update
the
BIOS
code,
following
the
instructions
that
come
with
the
update
file
that
you
downloaded.
This
will
automatically
restore
and
update
the
primary
page.
3.
Restart
the
blade
workstation.
If
that
procedure
fails,
the
blade
workstation
might
not
restart
correctly
or
might
not
display
video.
To
manually
restore
the
BIOS
code,
complete
the
following
steps:
1.
Read
the
safety
information
that
begins
on
page
vii
and
“Installation
guidelines”
on
page
13.
2.
Turn
off
the
blade
workstation.
3.
Remove
the
blade
workstation
from
the
BladeCenter
unit
(see
“Removing
the
blade
workstation
from
a
BladeCenter
unit”
on
page
16).
4.
Remove
the
cover
(see
“Removing
the
blade
workstation
