Table 3. System board jumpers
Jumper number Jumper name Jumper setting
JP2 Clear CMOS jumper
v Pins 1 and 2: Normal
(default) - This keeps the
CMOS data.
v Pins 2 and 3: This clears
the CMOS data such as
power-on password and
loads the default UEFI
settings.
JP3 UEFI boot recovery jumper
v Pins 1 and 2: Normal
(default) Loads the primary
firmware ROM page.
v Pins 2 and 3: Loads the
secondary (backup)
firmware ROM page.
Notes:
v If no jumper is present, the server responds as if the pins are set to 1 and 2.
v Changing the position of the UEFI recovery jumper from pins 1 and 2 to pins 2 and 3
before the server is turned on sets the UEFI recovery process. Do not change the jumper
pin position after the server is turned on. This can cause an unpredictable problem.
