Battery
Table 3-17 lists the pin signals of the External Battery Input header for backup CMOS RAM and RTC (Real
Time Clock), which uses 2 pins, single row, with 0.049" (1.25mm) pitch.
Note: The shaded table cells denote power or ground.
Ethernet External LED
This header provides signals for an external LED that indicates Ethernet links and activity using a single row
of 4 pins with 0.049" (1.25mm) pitch.
Note: The shaded table cell denotes power.
Miscellaneous
SSD (Solid State Drive)
The CoreModule 745 provides a standard SSD, which is a storage IC soldered directly onto the board. For
more information, refer to the SSD data sheet: http://www.greenliant.com/products/?inode=46780 .
Real Time Clock (RTC)
The CoreModule 745 contains a Real Time Clock (RTC). The RTC can be backed up with a battery. If the
battery is not present, the board BIOS has a battery-less boot feature to complete the boot process.
