Rtc Battery - Seco COM-Express CCOMe-965 User Manual

Three SMT LEDs are present near the Power Connector to indicate the state of Power Supply Voltage.
Red Led, D32: +5V_S ON
Yellow Led, D34: +5V_A ON
Green Led, D35: +3.3V_A ON
One pushbutton, M12, is located near the power connector, and has to be used to turn/on or off the power of the board, when in ATX mode.
Another pushbutton, M11, is located near the miniPCI-e Slot, and can be used to reset the system.

2.3.1 RTC Battery

For the occurrences when the system (Carrier Board + COM Express module) is not powered with an external power supply, on board there is a horizontal
battery holder, for the use of standard coin battery type BR2032 with a nominal capacity of 220mAh, to supply, with a 3V voltage, the Real Time Clock and CMOS
memory mounted on the COM Express module.
The batteries should only be replaced with devices of the same type. Always check the orientation before inserting and make sure that they are aligned correctly
and are not damaged or leaking.
Never allow the batteries to become short-circuited during handling.
CAUTION: handling batteries incorrectly or replacing with not-approved devices may present a risk of fire or explosion.
Batteries supplied with CCOMe-965 board are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting
out of order CCOMe-965 board, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European
Directive above mentioned. Even when replacing the batteries, the disposal has to be made according to these requirements.
2.3.2 Power Rails meanings
In all the tables contained in this manual, Power rails are named with the following meaning:
_S: Switched voltages, i.e. power rails that are active only when the board is in ACPI's S0 (Working) state. Examples: +3.3V_S, +5V_S.
_A: Always-on voltages, i.e. power rails that are active both in ACPI's S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_A, +3.3V_A.
_U: unswitched ACPI S3 voltages, i.e. power rails that are active both in ACPI's S0 (Working) and S3 (Standby) state. Examples: +1.5V_U
