The following table describes the jumpers on the system board.

Table 25. System board jumpers

Jumper number	Jumper name	Jumper setting
JP1	Clear CMOS jumper 1	v Pins 1 and 2: Keep CMOS data
		(default).
		v Pins 2 and 3: Clear CMOS data
		(including power-on password and
		administrator password)
JP6	Boot block jumper 2	v Pins 1 and 2: Boot from primary
		BIOS page (default) .
		v Pins 2 and 3: Boot from backup
		BIOS page.

Notes:

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.
