DS200TCEAG2B

The DS200TCEAG2B’s other troubleshooting tool is a series of LED lights mounted on the side of the circuit board. Visible when the board card is installed in the drive board cabinet. If the green LED lights up, the board is powered up and running. When the board blinks, it indicates that the board is normally processed. If the LED is not lit, the board is not powered up or running.
The DS200TCEAG2B circuit board is equipped with a number of capacitors to store current during the normal operation of the circuit board. The capacitor then releases voltage to power certain functions of the board. When you power down the drive, there may be a high voltage stored on the capacitor. Before you touch the board, wait 30 seconds after disconnecting the power from the driver to allow time for the power to exit from the capacitor
