General Procedure to Change Jumper Setting, CMOS Jumper

Page 68 highlights

General Procedure to Change Jumper Setting The short general procedure for changing a configuration setting is the same for most of the jumper functions, so we will describe it here. 1. Observe the safety and ESD precautions at the beginning of this chapter. 2. Turn off all connected peripherals, turn off system power, and disconnect the AC power cord. 3. Remove the side cover. You do not need to remove the server board from the chassis, and you probably do not need to remove any add-in boards. 4. Put a jumper on the pins specified for the desired setting. 5. Reinstall the side cover, connect the power cord, and turn on the system for the change to take effect. 6. You will need to remove the jumper back to its original setting to restore proper functionality. CMOS Jumper The jumper at pins 1-2 controls whether settings stored in CMOS nonvolatile memory (NVRAM) are retained during a system reset. Procedure to restore the system's CMOS and RTC to default values: 1. See "General Procedure to Change Jumper Setting" on page 68. 2. Install a jumper on pins 1 and 2 (the Clear CMOS memory position). 3. Reinstall the side cover for your safety, and connect the power cord to the system. 4. Turn the system on. Wait for POST to complete and for the messages "NVRAM cleared by jumper" and "Press F2 to enter Setup" to appear. This automatically reprograms CMOS and RTC to their default settings. 5. Enter Setup and make any changes necessary (for example, changing the boot device). Press to save the new Setup configuration and exit Setup. 6. Turn off the system, and disconnect the power cord from the system. 7. Remove the side cover. 8. Remove the jumper from pins 1-2. 9. Reinstall the side cover, and connect the power cord to the system. 10. Run BIOS Setup or the SSU to verify the correct settings. See Chapter 3. 68 Technical Reference

General Procedure to Change Jumper Setting
The short general procedure for changing a configuration setting is the same for most of the jumper
functions, so we will describe it here.
1.
Observe the safety and ESD precautions at the beginning of this chapter.
2.
Turn off all connected peripherals, turn off system power, and disconnect the AC power cord.
3.
Remove the side cover.
You do not need to remove the server board from the chassis, and you
probably do not need to remove any add-in boards.
4.
Put a jumper on the pins specified for the desired setting.
5.
Reinstall the side cover, connect the power cord, and turn on the system for the change to take
effect.
6.
You will need to remove the jumper back to its original setting to restore proper functionality.
CMOS Jumper
The jumper at pins 1-2 controls whether settings stored in CMOS nonvolatile memory (NVRAM)
are retained during a system reset.
Procedure to restore the system’s CMOS and RTC to default values:
1.
See “General Procedure to Change Jumper Setting” on page 68.
2.
Install a jumper on pins 1 and 2 (the Clear CMOS memory position).
3.
Reinstall the side cover for your safety, and connect the power cord to the system.
4.
Turn the system on.
Wait for POST to complete and for the messages
“NVRAM cleared by
jumper”
and
“Press F2 to enter Setup”
to appear.
This automatically reprograms CMOS
and RTC to their default settings.
5.
Enter Setup and make any changes necessary (for example, changing the boot device).
Press
<F10> to save the new Setup configuration and exit Setup.
6.
Turn off the system, and disconnect the power cord from the system.
7.
Remove the side cover.
8.
Remove the jumper from pins 1-2.
9.
Reinstall the side cover, and connect the power cord to the system.
10.
Run BIOS Setup or the SSU to verify the correct settings.
