A universal backplane connection for computer storage chassis. The overall backplane connection has at least one physical board that is connected to the SAS expander daughter board, and to the hard disk drives through its HDD (e.g. SAS) connector. Each universal backplane board has discrete components on-board, such as resistors, capacitors, voltage regulation ICs, Light Emitted Diodes (LED), HDD connector receptacles, power connector, General Purpose Input and Output ICs and a high-speed connector. Some of the discrete components and ICs regulate the DC current to provide a safe and stable power source to the HDDs. The HDD connector enables “hot-swap” function to the HDD, while other discrete components and amplifiers ensure data integrity of the system. LEDs provide a system status signal to the users. The high-speed connector, e.g. SAS connector, connects the universal backplanes to the SAS expander daughter board.
