About the DS3800HFPC1M1H
The GE Function Processor Board DS3800HFPC1M1H features a modular connector for attachment to a drive and retention levers to hold the board in the drive. The GE Function Processor Board DS3800HFPC1M1H also is populated with 8 jumpers, and multiple capacitors. The board also has 1 40-pin connector that is accessible from the front of the board. It also has standoffs for attaching a daughter card.
Another component on the board is a transistor to transistor logic (TTL) component. It serves as the interface logic between integrated circuits.
If you have a need for additional processing, you can add a daughter card to the GE Function Processor Board DS3800HFPC1M1H. The standoffs provide a means to attach the daughter card. The daughter card has 1 hole in each corner and the standoffs fit into each hole. The power and signals connections to the daughter card are made through the connector at the rear of the daughter card. When you press the daughter card into the standoffs, the power and signal connections are made though the connector.
The retention levers eliminate the need for screws to secure the board in the rack. The screws are prone to falling into the drive. Loose screws might cause an electrical short which can lead to fire or damage to the drive. The other consideration is that the screws might become lodged in the moving parts and jamb them from moving. This might damage the moving parts or the motor by preventing them from moving properly.
