Hitachi Global Storage Technologies 1 Connectors DC power requirements Pin 1 Pin A Jumper Power Block Connector AT I/F Connector The DC power connector is designed to mate with AMP p/n 1-80424-0 using AMP strip pins (p/n 350078-4), loose piece pins (p/n 61173-4), or their equivalents. Damage to the drive electronics may result if the power supply cable is connected or disconnected while the power is on. There is no special power on/off sequencing required.
