The following table describes the jumpers on the system board.

Table 6. 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.

Important:

1.Before you change any switch settings or move any jumpers, turn off the server; then, disconnect all power cords and external cables. Review the information in “Guidelines for trained service technicians” on page 115, “Handling static-sensitive devices” on page 117, and “Turning off the server” on page 113.

2.Any system-board switch or jumper blocks that are not shown in the illustrations in this document are reserved.
