Description

MOUNTING EXTENSION BARS ON POWER DISTRIBUTION UNITS
BACKGROUND
[0001] Computing centers such as data centers generally include a large number of computing devices. The computing devices can include, for example, servers, switches, routers, storage systems, and the like. A rack may provide a standardized structure to support and mount the computing devices. A power distribution unit (PDU) can also be mounted on the rack to provide electrical power to the computing devices via a plurality of receptacles on the PDU.

[0008] FIG. 6 is a perspective view of an example PDU with an extension bar mounted on the PDU and the PDU mounted on a rack. DETAILED DESCRIPTION
[0009] Examples described herein relate to mounting a power extension bar on a power distribution unit (PDU). In addition to computing devices that are mounted in a rack, a PDU can also be mounted in a rack to provide power to the computing devices. The devices include power cords that can be plugged into the power receptacles (or power outlets) of the PDU. A PDU can include circuitry to convert alternating current (AC) power to direct current (DC) power for the devices. A PDU can also include a circuit breaker for the power receptacles to protect the devices from damages caused by overload or short circuit, by interrupting current flow to the computing devices. A PDU can be vertically mounted in the rear of the rack to avoid taking space in the rack, where the devices are mounted. An equipment or electronic device mounted in the rear portion of the rack is referred to as a "zero U", as it takes up no space in the rack (i.e., does not take up a "U" position in the rack). Rack- mountable computing devices and equipment are measured in standard heights of 1.75 inches, referred to as "rack unit" or a "U." In some scenarios, a PDU can be a zero U device when it is mounted in the rear of a rack and does not take up space in the rack.
[0010] As described above, a plurality of devices can be coupled to the receptacles of the vertical mount PDU to receive power from the PDU. However, in certain scenarios, it may be desirable to provide additional power receptacles to power additional devices mounted on the rack if the PDU runs out of available power receptacles due to the number of devices coupled to the PDU. In such a scenario, a power extension bar may be required to provide additional power receptacles as needed within the rack. The PDU can provide electrical power to the extension bar which in turn provides the power to attached devices.
[0011] The described examples provide a solution for vertically mounting extension bars to a PDU to provide additional power receptacles in a rack. The examples describe a vertical mounted PDU that includes mounting buttons to receive a mounting bracket, where the extension bar is vertically mounted onto a surface (e.g., left, right, or back surface) of the PDU via the mounting bracket.
[0012] In one example, a power distribution unit (PDU) includes a front surface, side surfaces and a back surface. The front surface includes a plurality of receptacles to couple a power cord of a power extension bar to the PDU. The side surfaces and the back surface include mounting buttons removably attachable to the PDU. The mounting buttons are to receive a mounting bracket to mount the extension bar to the PDU.
[0013] In another example, a power distribution system includes a power distribution unit (PDU) that includes a plurality of power outlets on a front side of the PDU and mounting buttons to removably attach to at least one of a left side, a right side, and a back side of the PDU. The power distribution system also includes a power extension bar mountable on at least one of the left side, the right side, and the back side of the PDU via a mounting bracket to couple to the mounting buttons of the PDU, where the extension bar includes a power cable to couple to a power outlet of the PDU.
[0014] Referring now to the figures, FIG. 1 is a perspective view of an example implementation of mounting an extension bar on a power distribution unit (PDU). PDU 100 includes a front surface 116 (or front side), a back surface, a left surface 166, and a right surface. Front surface 116 of the PDU 100 includes a plurality of receptacles 106 (or power outlets) to removably plug in power cords of computing devices and other electrical equipment of the rack to provide power to the computing devices and equipment. Computing devices can include rack-mountable computing devices such as servers, networking devices, storage devices, etc.
[0015] PDU 100 includes a left surface 166 (or left side) with mounting buttons 102 removably inserted into mounting holes (not shown) of the PDU 100. Mounting buttons 102 include any connectors or mounting features to engage with
corresponding mounting features 134 on a mounting bracket 130. Each mounting feature 134 can be an opening, recess, or cavity in the mounting bracket, to receive or engage with the mounting buttons 102. Mounting bracket 130 can be metallic or non- metallic (e.g., plastic, polymer, etc.) material to mount the extension bar 140 onto one of the sides of the PDU 100. In the example of FIG. 1, mounting bracket 130 can be used to vertically mount extension bar 140 onto the left side 166 of PDU 100.
Mounting bracket 130 can include mounting holes 138 on a top portion and a bottom portion to enable the extension bar 140 to be mounted via screws 136 to the mounting bracket. Accordingly, extension bar 146 can include corresponding mounting holes 146 on a top portion and a bottom portion where the screws 136 are inserted to secure the extension bar onto the mounting bracket 130. [0016] Extension bar 140 includes a power cord 144 to attach to a receptacle 106 of the PDU 100 to receive power from the PDU 100. For example, power receptacles 106 of the PDU can include a number of International Electrotechnical Commission (IEC) C19 and C13 receptacles, and extension bar can be coupled to a C 19 receptacle of the PDU 100 via power cable 144. Extension bar 140 can include a plurality of receptacles 142 to provide power to devices attached to the extension bar 140. For example, extension bar 140 can include a number of C13 receptacles to provide output power from the PDU 100 to a plurality of devices coupled to the extension bar 140.
[0017] PDU 100 can also include other components such as a breaker box to protect the computing devices from damages caused by overload or short circuit, a power cord 120 to couple the PDU to a main power supply, a data communication port, and a display area (e.g., light emitting diode (LED) display), among others.
[0018] FIG. 2 is a perspective view of an example PDU with extension bars mounted on a left side of the PDU. In the example of FIG. 2, extension bar 140 and a second extension bar 240 are both mounted, via respective mounting bracket 130 and a second mounting bracket 230, on the left surface 166 of the PDU 100.
[0019] Extension bar 140 is vertically mounted onto a top portion of the left surface 166 of the PDU 100 using the mounting bracket 130. Mounting bracket 130 is received by a first set of mounting buttons (e.g., top two mounting buttons) on the left surface 166 of the PDU 100. Second extension bar 240 is vertically mounted onto a bottom portion of the left surface 166 of the PDU 100 using the second mounting bracket 230. Second mounting bracket 230 is received by a second set of mounting buttons (e.g., bottom two mounting buttons) on the left surface 166 of the PDU 100.
[0020] Further, extension bar 140 is connected to a power receptacle 106 on the front surface 116 of the PDU 100 and second extension bar 240 is connected to another power receptacle 206 on the front surface 116 of the PDU, via respective power cords 144 and 244. Extension bar 140 and second extension bar 240 each include a plurality of receptacles to provide power to devices attached thereto. In the example of FIG. 2, because the extension bars 140 and 240 are mounted on the left surface 166 of the PDU 100, the PDU 100 can be mounted vertically onto a rack using the right surface of the PDU 100 or the back surface of the PDU 100. [0021] FIG. 3 is a perspective view of an example PDU with extension bars mounted on a right side of the PDU.
