Description
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.
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.
