Move the jumper to pins 2 and 3 to use the secondary page during startup. Force BMC update (J57) Place a jumper over pins 1 and 2 to bypass the operational firmware image and perform a baseboard management controller firmware update, if the operational image is corrupted. Note: Only use the force BMC update jumper if the normal firmware update procedure fails and the operational firmware image is corrupted. Use of the force BMC update jumper disables normal baseboard management controller operation. 22 IBM System x3850 M2 and System x3950 M2 Type 7141: User's Guide

Description
Boot
recovery
(BIOS)
(J17)
The
default
position
is
pins
1
and
2
(use
the
primary
page
during
startup).
Move
the
jumper
to
pins
2
and
3
to
use
the
secondary
page
during
startup.
Force
BMC
update
(J57)
Place
a
jumper
over
pins
1
and
2
to
bypass
the
operational
firmware
image
and
perform
a
baseboard
management
controller
firmware
update,
if
the
operational
image
is
corrupted.
Note:
Only
use
the
force
BMC
update
jumper
if
the
normal
firmware
update
procedure
fails
and
the
operational
firmware
image
is
corrupted.
Use
of
the
force
BMC
update
jumper
disables
normal
baseboard
management
controller
operation.
