Setting the system board jumpers 71
The following table shows the settings required to allow programming of the
BMC boot block. Make sure you turn off the server and unplug the power
cord before moving the jumper.
FRB Enable jumper
The server supports fault resilient booting (FRB) which causes the second
processor to take over the boot process if the first processor fails to respond
within a specified time. The FRB Enable jumper on the system board (pins 1
through 3 on jumper J3J1) lets you enable FRB. (See the figure on page 6 for
the location of the jumper.)
The following table shows the settings required to enable FRB. Make sure you
turn off the server and unplug the power cord before moving the jumper.
