Battery Installation
2 - 26 PENT/CPCI-721
Battery
The board is designed to be maintenance-free. However, note that a
Lithium battery is installed on the board. The battery provides a data
retention of five years summing up all periods of actual battery use.
Therefore Force Computers assumes that there usually is no need to
exchange the Lithium battery except for example in the case of long-
term spare part handling.
Caution
• Incorrect exchange of Lithium batteries can result in a hazardous
explosion.
• Exchange the battery before five years of actual battery use have
elapsed.
• Exchanging the battery always results in data loss of the devices
which use the battery as power backup. Therefore, back up
affected data before exchanging the battery.
• Always use the same type of Lithium battery as is already
installed.
• If the battery is covered by a PMC module on slot 1 or a memory
module, the module must be removed first.
• Do not use a screwdriver to remove the battery from its holder to
avoid possible damage to the PCB or the battery holder.
• When installing the new battery ensure that the ‘+’ on top of the
battery stays at the top and therefore is visible when viewing the
board from its component side.
• If necessary reinstall the PMC or memory module in its correct
position.
