The external lithium ion battery supplies power to the real-time clock and CMOS memory as an
auxiliary source of power when the main power is shut off.
Safety Measures
• There exists explosion hazard if the battery is incorrectly installed.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to local ordinances.
The board supports the chassis intrusion detection function. Connect the chassis intrusion sensor
cable from the chassis to this connector. When the system’s power is on and a chassis intrusion
occurred, an alarm will sound. When the system’s power is off and a chassis intrusion occurred,
the alarm will sound only when the system restarts.
