Abstract

Examples described herein relate to power distribution units (PDUs) with receptacles on one surface and branch rated circuit protection devices on an opposite surface. For example, a PDU includes a first surface including a plurality of receptacles to couple a plurality of electronic devices to the PDU. The PDU also includes a second surface, opposite the first surface, including a plurality of branch rated circuit protection devices associated with the plurality of receptacles.

First claim

What is claimed is:

1. A power distribution unit (PDU), comprising:
a first surface including a plurality of receptacles to couple a plurality of electronic devices to the PDU;
a second surface, opposite the first surface, including a plurality of branch rated circuit protection devices aligned with the plurality of receptacles; and
a mounting mechanism on a side surface of the PDU to vertically mount the PDU on a vertical column of a rack, wherein the plurality of receptacles are to face a back end of the rack.

2. The PDU of claim 1 , wherein the branch rated circuit protection devices include a circuit breaker or a removable fuse.

3. The PDU of claim 1 , wherein the plurality of receptacles comprise a number of groups of receptacles, wherein each group of receptacles is aligned with a branch rated circuit protection device of the plurality of branch rated circuit devices.

4. The PDU of claim 3 , comprising a first visual indicator to represent a first group of receptacles aligned with a first branch rated circuit device and a second visual indicator to represent a second group of receptacles aligned with a second branch rated circuit device, wherein the first visual indicator is different from the second visual indicator.

5. The PDU of claim 1 , wherein a width of the PDU is less than or equal to 52 millimeters (mm).

6. The PDU of claim 1 , comprising a power cord or a terminal block to couple the PDU to a main power supply or to a backup power supply.

7. The PDU of claim 6 , wherein the power cord or terminal block is located at a top surface of the PDU or at a bottom surface of the PDU.

8. The PDU of claim 1 , wherein the PDU comprises a zero rack unit (0U) vertical PDU.

9. The PDU of claim 1 , wherein the plurality of receptacles comprise International Electrotechnical Commission (IEC) C13 or C19 receptacles.

10. The PDU of claim 1 , wherein the plurality of receptacles are on the exterior surface of the first surface and the plurality of branch rated circuit protection devices are on the exterior surface of the second surface.

11. The PDU of claim 1 , wherein the second surface further comprises a back surface, and wherein the first surface further comprises a front surface opposite the back surface.

12. A power distribution unit (PDU), comprising:
a plurality of power receptacles on a front surface of the PDU to distribute power to a plurality of electronic devices coupled to the PDU;
a plurality of branch rated circuit protection devices on a back surface, opposite the front surface, of the PDU, the plurality of branch rated circuit protection devices aligned with the plurality of power receptacles; and
a mounting mechanism on a side surface of the PDU to vertically mount the PDU on a vertical column of a rack, wherein the plurality of receptacles are to face a back end of the rack.

13. The PDU of claim 12 , wherein a set of power receptacles of the plurality of power receptacles is protected by an aligned branch rated circuit protection device of the plurality of branch rated circuit protection devices.

14. The PDU of claim 12 , comprising visual indicators to align a set of power receptacles to an aligned branch rated circuit protection device.

15. A system, comprising:
a rack enclosure comprising vertical columns; and
a power distribution unit (PDU), comprising:
a plurality of receptacles on a first surface of the PDU to provide power to a plurality of electronic devices coupled to the PDU;
a plurality of branch rated circuit protection devices on a second surface of the PDU opposite the first surface, the branch rated circuit protection devices aligned with the plurality of receptacles to protect the plurality of receptacles; and
a plurality of mounting pins removably attachable to a side of the PDU to mount the PDU on a vertical column of a rack, wherein the plurality of receptacles are to face a back end of the rack.

16. The system of claim 15 , wherein the mounting pins are removably attachable to corresponding plurality of mounting holes on the vertical column of the rack enclosure.
