60 Keysight M9037A PXIe Embedded Controller User Guide
Controller Maintenance BIOS Setup
Clear CMOS
If you encounter an abnormal condition that causes M9037A to halt or fail to
boot, clear the CMOS and restore the controller BIOS to its factory default
settings.
To clear the CMOS:
1 Shut down the controller operating system. Do not unplug the chassis from
the AC power.
2 Remove the M9037A Embedded Controller from the chassis. Observe all
anti-static precautions.
3 Locate the Clear CMOS switch on the board. It is near the CMOS backup
battery. Move the switch from Normal to Clear. Refer to Figure 12 below.
4 Wait at least 30 seconds then return the switch to its Normal position.
5 Reinstall the controller back into the PXIe chassis.
6 Power on the chassis.
7 Press the <Delete> key when the controller beeps. This should be concurrent
with the main startup screen. The BIOS setup program loads after a short
delay.
8 Load Optimized defaults in the BIOS setup.
j The Main setup menu reports some basic information of controller. Refer to
“BIOS Settings” on page 34 for more information.
k Use the down arrow key (
↓) to select the System Date and System Time.
l Set these to the correct current date and time.
m Press the <F4> key to save the settings and then the <ESC> key to exit the
BIOS setup.
Always observe ESD precautions. See “Electrostatic Discharge
(ESD)” on page 59.
System date and time should be set before pressing F4. F4 saves
and then exits the BIOS setup utility. If the BIOS data is not saved
before exiting the utility, then the last BIOS settings remain.
