WARNING:
The system default power is 120 W. The maximum total power of the
backplane to support expansion cards is 45 W. The power of the
selected expansion cards can not exceed the max. power (45 W),
otherwise, the system may be unstable.
NOTE:
When using an expansion card with high power consumption, it is
recommended to install an external power supply to the power input
connector on the backplane.
The backplane support standard PCI/PCIe cards with maximum
dimensions (WxL):110 x 230 mm.
The TANK-870-Q170 provides the most convenient 4-pin internal power connector for
add-on card usage, adding more flexibility to the embedded system in industrial
environment. The internal power connector supports 5V@3A or 12V@3A power supply.
