ADLINK PXIe-3985 - Manual (Page 34)

22 Getting Started
2.2.4 Replacing the Battery Backup
The PXIe-3985 is provided with a 3.0 V “coin cell” lithium battery,
replacement of which is as follows.
1. Turn off the PXI chassis.
2. Remove the PXIe-3985 embedded controller from
the chassis. Observe all anti-static precautions.
3. To remove the battery, gently insert a small (approx. 5
mm) flathead screwdriver under the battery at the nega-
tive retaining clip. Gently pry up and the battery should
easily pop out.
4. Place a fresh identical battery (CR2032 or equivalent) in
the socket, ensuring that the positive pole (+) is facing
upwards. The battery is most easily seated by first being
inserted under the positive retaining clip, and then
pushed downward at the negative retaining clip. The bat-
tery should easily snap into position.
5. Reinstall the embedded controller into the PXI chassis
and restore power.
2.2.5 Clearing CMOS
In the event of a system malfunction causing the PXIe-3985 to halt
or fail to boot, clear the CMOS and restore the controller BIOS to
its default settings. To clear the CMOS:
1. Shut down the controller operating system and turn off
the PXI Chassis.
2. Remove the PXIe-3985 from the chassis. Observe
all anti-static precautions.
3. Locate the CMOS clear switch (SW1) on the board (see
Section 1.3.9: Onboard Connections and Settings).
Move the switch from Normal position
