Abstract
A data management system includes a chassis metalwork that is electrically conductive. The chassis metalwork is electrically coupled to the power supply to form a return power path. The return power path may include a sub-chassis frame and a drawer frame. The return power path may also include uninsulated return power cables. The return power cables may be maintained in a cable chain along with outgoing power cables and data cables. The return power cables may be coupled to the drawer frame and the sub-chassis frame.
Claims20
A system comprising:
- a sub-chassis comprising an electrically-conductive sub-chassis frame;
- a drawer frame being electrically conductive and mechanically coupled to the sub-chassis;
- a first power supply fixedly coupled relative to the sub-chassis and comprising a first terminal and a second terminal, the first power supply configured to drive a current via the first and second terminals to provide electrical power to an active device disposed in the drawer frame;
- and
- a first power cable being electrically coupled to the first terminal of the first power supply via the sub-chassis frame and being electrically coupled to the active device via the drawer frame.
2 more elements
A system comprising:
- an active device comprising a first power connection and a second power connection;
- a drawer frame being electrically conductive and electrically coupled to the first power connection of the active device at a first connection on the drawer frame;
- a power cable being electrically coupled to the drawer frame at a second connection on the drawer frame different than the first connection;
- a sub-chassis comprising an electrically-conductive sub-chassis frame electrically coupled to the first power cable and a backplane comprising a backplane electrical conductor electrically coupled to the sub-chassis frame;
- and
- a power supply comprising a first terminal and a second terminal to deliver electrical power, the first terminal being electrically coupled to the backplane electrical conductor and a second terminal, the second terminal being electrically coupled to the second power connection of the active device.
3 more elements
A method comprising:
- electrically coupling an electrically conductive frame of a chassis to a first terminal of a power supply, the chassis comprising a front portion and a rear portion, the power supply being disposed in the rear portion, the power supply configured to drive a current via the first terminal and a second terminal to provide electrical power;
- and
- electrically coupling a first power connection of an active device to the first terminal of the power supply via the frame, the active device comprising at least one of a server and a storage device, the active device being disposed in the front portion of the chassis;
- electrically coupling a second power connection of the active device to the second terminal of the power supply via a power cable.
