Jumper Jumper
number name
Note:
1. If no jumper is present, the server responds as if the pins are set to 1 and 2.
2. Changing the position of the UEFI boot recovery jumper from pins 1 and 2 to pins 2
and 3 before the server is turned on alters which flash ROM page is loaded. Do not
change the jumper pin position after the server is turned on. This can cause an
unpredictable problem.
The following illustration shows the jumper settings for switch blocks SW3 and
SW4 on the system board.
