System Battery Replacement
Overview
The EPC-3221 utilizes a CR2032 lithium (Li/MnO
battery provides power to retain the correct date, time, and computer parameters in CMOS
when the system is powered-off. This information assists the BIOS in performing initialization
and configuration during power-on or reset operations.
Service
The system battery is designed to provide years of service without replacement. However, if
configuration or clock-related inconsistencies occur, the battery may need to be replaced.
Installation
To install the system battery
1. Power-off the system and disconnect all power cords.
Note: Use a grounding wrist strap or other static-dissipating device when accessing and
handling the equipment.
2. Remove the SCB from the chassis.
3. Orient the battery with its positive pole (top surface) toward the front of the connector.
Note: The battery will not discharge voltage if installed backwards.
4. Rotate the upper edge of the battery approximately 45° away from the battery connector.
5. Insert the lower edge of the battery into the connector, so that the negative pole (bottom
surface) of the battery engages the negative spring contact of the connector.
6. Press the raised edge of the battery downward until the battery seats firmly in the battery
connector.
Note: The positive spring contact of the connector will engage the positive pole of the
battery.
