Caution Moving the jumper while the power is on can damage the server. Always 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.
