Table 2. System board jumpers (continued)
Jumper number Jumper name Jumper setting
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 BIOS recovery jumper from pins 1 and 2 to pins 2 and 3
before the server is turned on sets the BIOS recovery process. 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 22, “Handling static-sensitive devices” on page
23, and “Turning off the server” on page 13.
2. Any system-board switch blocks or jumpers that are not shown in the
illustrations in this document are reserved.
