The GE Regulator Board DS3800HAFA1E1F features a modular connector for attachment to a drive and retention levers to hold the board in the drive. The GE Regulator Board DS3800HAFA1E1F also is populated with 11 jumpers, and 4 trimmer resistor components. The board also has 1 20-pin connector and 1 34-pin connector.
The GE Regulator Board DS3800HAFA1E1F is populated with test points that provide an opportunity to troubleshoot the board, if any problems occur. If the board is experiencing intermittent problems or has suddenly stopped processing as you expect, the first step is to power off the drive. Be aware that the drive has several power sources and you must remove all power to the drive. You might want to consult with engineers at the site or with other technicians familiar with the installation, if you are unfamiliar with the power sources. Use a testing device to test for the presence of current before you touch any components.
Wait 30 seconds for all power to exit the board. Open the levers and disconnect the board from the modular connector at the rear of the rack. Then, reinstall the board. Restart the drive. This might clear any problems or signal errors.
If the errors persist, a qualified servicer can use the test points to test the various circuits on the board. This should take place on a clean and flat surface, for example a workbench or desk. Lay the board on an empty and flat static protective bag. The qualified individual will have the proper testing equipment to perform the testing.
