2.5 System Indicators
The PCIeCANFD-400U interface card has 1 system operation indicator, 1 dual-color CAN0 indicator, 1
dual-color CAN1 indicator, 1 dual-color CAN2 indicator, and 1 dual-color CAN3 indicator to indicate the device
operating status. To facilitate the user's observation, the indicators are located at the rear of the board. Table 2.1
lists the indicator functions. When the indicators are in various states, the state of the CAN bus is shown in Table
2.2.

Description
FPGA_RUN
Green
Device running properly
CANX_RUN
Green
CAN channel start
Red
CAN channel error
Light off
CAN channel not started
After the PCIeCANFD-400U interface card is powered on, the system status indicator FPGA_RUN is green,
indicating that the device is powered on, and the system is operating properly; if the system status indicator
FPGA_RUN is off, the system power supply fails or a critical fault occurs in the system.
When the CANX_RUN indicator is green, the CAN controller has been initialized and is working properly.
When the CAN controller has an error, the CANX_RUN indicator is red; when the error of the CAN controller
is cleared, the CANX_RUN indicator is green.
