According to another aspect of the present invention, the ports input or output to the first input and output terminal provides an expansion adapter for the ODD module and HDD module including IEEE 1394 serial, USB 2.0 (or USB 1.1), and Serial ATA. .

According to yet another aspect of the present invention, there is provided an expansion adapter for an ODD module and an HDD module, wherein the first voltage is about 12V and the second voltage is about 12V or 5V.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1, there is shown a schematic diagram of an ODD module, an HDD module and an expansion adapter. The ODD module and HDD module 11 are some of the components of a modular personal computer such as a CPU module, I / O expansion module, heat dissipation module, rear port module, interface module, power supply module, heat dissipation fan module, and the like. Therefore, the ODD module and the HDD module produced during the development process of the modular personal computer are used as they are.

The expansion adapter 12 for the ODD module and the HDD module is a first input / output terminal, an IEEE 1394 port 13, which is a kind of serial bus, a USB 2.0 port 14 including a universal serial bus (USB) 1.1, and a serial ATA (Serial). Advanced Technology Attachment) 15 and a 12V power supply 16. The ODD module and the HDD expansion adapter including the first input / output terminal are coupled to the ODD module and the HDD module, and the ODD module and the HDD module to which the expansion adapter is combined are used for personal computers other than the modular personal computer. It becomes possible. In addition, the expansion adapter is connected to a personal computer other than the personal computer through the IEEE 1394, Serial ATA and USB 2.0 (or USB 1.1) signal, so that the hot plug and play function of the signals (i.e., The function of connecting or disconnecting the cable while the power is on) enables the ODD module and HDD modules to be used freely without turning on or off the power of the personal computer.
