v
Pins 1 and 2: Boot from primary

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 “Installation guidelines” on page 25,
“Handling static-sensitive devices” on page 26, and “Turning off the server” on page 22.
2.
Any system-board switch or jumper blocks that are not shown in the illustrations in this document
are reserved.
