The GE Emergency Overdrive board DS200TCEAG2B has a microprocessor and slots for multiple erasable Programmable read-only memory (EPROM) modules. It also contains 3 fuses, 30 jumpers, and a pair of bayonet connectors. The GE Emergency Overdrive plate DS200TCEAG2B is also equipped with multiple test points. Test points enable service personnel with appropriate equipment to test the circuit on the board. Each test point has an ID. Some of the ids assigned to the test point are ANALOG OUTPUT, COM, P5, JW, and RESET. Circuit testing is a valuable troubleshooting tool if you suspect the board is not working properly.

Another 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
