5. Locate the force BMC override switch (switch 4 of SW1) on the system board, removing any components that impede access to the switch. 6. Move switch 4 of SW1 to the ON position. 7. Replace any components that were removed. 8. Replace the cover. 9. Connect the server to a power source, keyboard, monitor, and mouse. You will now be able to start the server. When you start the server, you must update the BMC firmware code (see "Updating the BMC firmware" on page 95). When the update is complete, return switch 4 of SW1 to the OFF position. Small computer system interface messages If you receive a SCSI error message, see "SCSI error codes" on page 132. Note: If your server does not have a hard disk drive, ignore any message that indicates that the BIOS is not installed. Recovering the BIOS code If power to the server is interrupted while POST/BIOS code is being updated (flash update), the server might not restart (reboot) correctly or might not display video (no video). If this happens, you will need a BIOS recovery diskette. To create this diskette, download the BIOS recovery disk image from http://www.ibm.com/support/ and follow the directions in the image's included readme file. Using the BIOS recovery diskette, complete the following steps to recover the BIOS code: 1. Read Appendix B, "Safety information," on page 153 and "Handling static-sensitive devices" on page 12. 2. Turn off the server and all attached devices. 3. Disconnect the power cord; then, disconnect all external cables. 4. Remove the cover (see "Removing the left-side cover" on page 14). 5. Locate the BIOS boot block jumper (J5) on the system board, removing any components that impede access to the jumper. Chapter 5. Diagnostics 97

messages
If
you
receive
a
SCSI
error
message,
see
“SCSI
error
codes”
on
page
132.
Note:
If
your
server
does
not
have
a
hard
disk
drive,
ignore
any
message
that
indicates
that
the
BIOS
is
not
installed.
Recovering
the
BIOS
code
If
power
to
the
server
is
interrupted
while
POST/BIOS
code
is
being
updated
(flash
update),
the
server
might
not
restart
(reboot)
correctly
or
might
not
display
video
(no
video).
If
this
happens,
you
will
need
a
BIOS
recovery
diskette.
To
create
this
diskette,
download
the
BIOS
recovery
disk
image
from
and
follow
the
directions
in
the
image’s
included
readme
file.
Using
the
BIOS
recovery
diskette,
complete
the
following
steps
to
recover
the
BIOS
code:
1.
Read
Appendix
B,
“Safety
information,”
on
page
153
and
“Handling
static-sensitive
devices”
on
page
12.
2.
Turn
off
the
server
and
all
attached
devices.
3.
Disconnect
the
power
cord;
then,
disconnect
all
external
cables.
4.
Remove
the
cover
(see
“Removing
the
left-side
cover”
on
page
14).
5.
Locate
the
BIOS
boot
block
jumper
(J5)
on
the
system
board,
removing
any
components
that
impede
access
to
the
jumper.
