The following illustration shows the location and description
of the switches and jumpers.
Figure 1. Location and description of switches and jumpers
Note: If there is a clear protective sticker on the top of the
switch blocks, you must remove and discard it to access the switches.
The following table describes the jumpers on the system
board.
Table 1. System board jumpers
Jumper name |
Jumper setting |
Clear CMOS jumper |
- Pins 1 and 2: Normal (default).
- Pins 2 and 3: Clears the real-time clock (RTC) registry.
|
UEFI boot recovery jumper |
- Pins 1 and 2: Normal (default). Boots from the primary page.
- Pins 2 and 3: Boots from the secondary (backup) page.
|
Note:
- If no jumper is present, the server responds as if the pins are
set to the default.
- Changing the position of the UEFI boot backup jumper (JP2) 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.
