Using the force BMC update jumper
If the normal firmware update procedure results in an inoperative BMC, change the
position of the force BMC update jumper (J57 on the microprocessor board) to
bypass the operational firmware image.
Attention:
Before changing any switch settings or moving any jumpers, turn off
the server; then, disconnect all power cords and external cables. See the safety
information beginning on page v. Do not change settings or move jumpers on any
system-board switch or jumper blocks that are not shown in this document.

While the server is turned off, place a jumper over pins 1 and 2 on J57. Then,
perform a firmware update. Turn off the server again and remove the jumper from
pins 1 and 2.
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.
