Jumper Block Settings
Note: Normal BMC functionality is disabled with the force BMC update jumper set to the "enabled"
position. The server should never be run with the BMC force update jumper set in this position and should
only be used when the standard firmware update process fails. This jumper should remain in the default –
disabled position when the server is running normally.

BIOS Select Jumper
The jumper block at J3H1, located just to the left of the SSI control panel header, is used to select which
BIOS image the system will boot to. Pin 1 on the jumper is identified with a '▼'. This jumper should only
be moved if you wish to force the BIOS to boot to the secondary bank which may hold a different version
of BIOS.
