ABSTRACT:
The present invention relates to a circuit mounting unit that can prevent a voltage drop and noise occurrence due to current inflow at the time of a hot insertion or withdrawal operation without mounting a capacitor with large capacitance on the side of a main unit. The circuit mounting unit includes a first voltage control unit that controls to increase gradually a voltage supplied to a load voltage converter from the main unit side to a predetermined voltage when the circuit mounting unit is exchangeably inserted into or pulled out of the main unit without halting electric power supplied from the main unit. The circuit mounting unit is mounted onto a printed wiring board on which various elements such as ICs and LSIs are previously mounted to form a predetermined circuit.
