Description

Technical Field

[0001] This application relates to the field of power distribution unit technology, and in particular to a rack-mounted power distribution unit. Background Technology

[0002] A rack power distribution unit (rPDU) is a power distribution and management device installed on a server rack. It is mainly used to distribute power from a single input to multiple outputs to meet the power needs of various IT devices in the rack. Rack power distribution units are widely used in data centers, network rooms, computer rooms and other similar locations.

[0003] However, due to their inherent structural design, rack-mounted power distribution units in related technologies cause all loads connected to the unit to lose power if even one of them becomes overloaded. Therefore, it is necessary to design a new type of rack-mounted power distribution unit that, in the event of an overload, only causes power loss to the power supply branch containing the overloaded load, while the power supply branches containing the remaining loads continue to operate normally. Utility Model Content

[0004] This application provides a rack-mounted power distribution unit that can solve the problem in related technologies where, due to the structural design of rack-mounted power distribution units, if even one of the multiple loads connected to the rack-mounted power distribution unit is overloaded, all loads connected to the rack-mounted power distribution unit will lose power.

[0005] This application provides a rack-mounted power distribution unit. The rack-mounted power distribution unit includes a connection module, a socket module, a connection component, and a distributed switch unit. The connection module is used to connect to a power supply unit to receive power signals. The socket module includes multiple socket units, which are used to connect to external devices to supply power to the external devices. The connection component is connected to the connection module to receive power signals. The distributed switch unit is connected between at least one socket unit and the connection component, and the distributed switch unit is used to control whether the power signal from the connection component is provided to at least one socket unit.

[0006] Based on the rack-mounted power distribution unit of this application embodiment, a distributed switching unit is designed. The distributed switching unit has an on state and an off state. The connection module, connection component, distributed switching unit and socket unit of the socket module cooperate with each other to form a power supply branch. When the external device is overloaded, the distributed switching unit is in the off state. At this time, only the power supply branch of the overloaded external device is de-energized, and the power supply branch of the other non-overloaded external devices can work normally, thereby realizing the branch power supply control of multiple external devices connected to multiple socket units of the socket module.

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] Please refer to Figures 1-2 As shown, this application proposes a rack-mounted power distribution unit 1, which includes a connection module 10, a socket module 20, a connection component 30, and a distributed switching unit 40. The connection module 10 is used to connect to a power supply unit 2 to receive power signals. The socket module 20 includes multiple socket units 20a, which are used to connect to external devices to supply power to those devices. The connection component 30 is connected to the connection module 10 to receive power signals. The distributed switching unit 40 is connected between at least one socket unit 20a and the connection component 30, and is used to control whether a power signal from the connection component 30 is provided to at least one socket unit 20a.

[0019] The following combination Figures 1-8 The specific structure of rack-mounted power distribution unit 1 will be described in detail.

[0020] like Figures 1-2 As shown, the rack-mounted power distribution unit 1 includes a connection module 10, a socket module 20, a connection component 30, and a distributed switching unit 40.

[0021] The connection module 10 serves as the signal access structure for the rack-mounted power distribution unit 1. The connection module 10 is used to connect to the power supply unit 2 to receive power signals; the power supply unit 2 may include, but is not limited to, the power grid. The specific structure of the connection module 10 will be described in detail below.

[0022] The socket module 20 serves as the signal output structure of the rack-mounted power distribution unit 1. The socket module 20 includes multiple socket units 20a, which are used to connect external devices to supply power to them. These external devices may include, but are not limited to, electrical appliances such as computers and air conditioners. The specific structure of the socket unit 20a will be described in detail below.

[0023] The connection component 30 serves as the electrical connection structure of the rack-mounted power distribution unit 1. The specific structure of the connection component 30 will be described in detail below.

[0024] The connection component 30 is connected to the connection module 10 to receive power signals.

[0025] The distributed switching unit 40 serves as the electrical switching structure of the rack-mounted power distribution unit 1. The specific structure of the distributed switching unit 40 will be described in detail below.

[0026] A distributed switching unit 40 is connected between at least one socket unit 20a and the connection component 30. The distributed switching unit 40 is used to control whether a power signal from the connection component 30 is provided to at least one socket unit 20a. For example, when only some socket units 20a are connected to the connection component 30 via the distributed switching unit 40, the distributed switching unit 40 controls whether a power signal from the connection component 30 is provided to the corresponding socket unit 20a (i.e., the aforementioned partial socket units 20a), while the remaining socket units 20a are directly connected to the connection component 30 to receive power signals. As another example, when all socket units 20a are connected to the connection component 30 via the distributed switching unit 40, the distributed switching unit 40 controls whether a power signal from the connection component 30 is provided to all socket units 20a.

[0027] It is understood that the distributed switch unit 40 has an on state and an off state. When the distributed switch unit 40 is in the on state, it can control the power signal from the connection component 30 to be supplied to the socket unit 20a. The power supply branch formed by the connection module 10, the connection component 30, the distributed switch unit 40, and the socket unit 20a is connected, and the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. When the distributed switch unit 40 is in the off state, it cannot control the power signal from the connection component 30 to be supplied to the socket unit 20a. The power supply branch formed by the connection module 10, the connection component 30, the distributed switch unit 40, and the socket unit 20a is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0028] The switching of the distributed switching unit 40 between the aforementioned on-state and off-state can be achieved through manual control or automatic control. Specifically, manual control can be achieved by the user manually pressing the button; automatic control can also be achieved by combining the detection unit to detect the operating status (such as voltage, current, and power status) of at least one module, unit, or unit of the rack-mounted power distribution unit 1, and automatically controlling the on and off states of the distributed switching unit 40 based on the detection results.

[0029] Based on the rack-mounted power distribution unit 1 in this application embodiment, a distributed switch unit 40 is designed. The distributed switch unit 40 has an on state and an off state. The connection module 10, the connection component 30, the distributed switch unit 40 and the socket unit 20a of the socket module 20 cooperate to form a power supply branch. When the external device is overloaded, the distributed switch unit 40 is in the off state. At this time, only the power supply branch where the overloaded external device is located loses power, while the power supply branches where the other non-overloaded external devices are located can work normally. This realizes the branch power supply control of multiple external devices connected to multiple socket units 20a of the socket module 20.

[0030] like Figure 1 and Figure 3 As shown, the distributed switch unit 40 includes a plurality of distributed switches 41, each distributed switch 41 being connected between a corresponding socket unit 20a and the connection component 30. The distributed switch 41 is used to control whether the power signal from the connection component 30 is provided to the corresponding socket unit 20a.

[0031] Each distributed switch 41 has an on state and an off state. When the distributed switch 41 is in the on state, it can control the power signal from the connection component 30 to be supplied to the corresponding socket unit 20a. The power supply branch formed by the connection module 10, the connection component 30, the distributed switch 41 and the corresponding socket unit 20a is connected, and the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. When the distributed switch 41 is in the off state, it cannot control the power signal from the connection component 30 to be supplied to the corresponding socket unit 20a. The power supply branch formed by the connection module 10, the connection component 30, the distributed switch 41 and the corresponding socket unit 20a is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the socket module 20 includes a first socket module 201, a second socket module 202, and a third socket module 203; the connection component 30 includes a first live wire connector L1, a second live wire connector L2, a third live wire connector L3, a neutral wire connector N, and a ground wire connector PE; the first socket module 201 is connected to the first live wire connector L1, the second socket module 202 is connected to the second live wire connector L2, and the third socket module 203 is connected to the third live wire connector L3.

[0033] The multiple distributed switches 41 include multiple first switches K1, multiple second switches K2 and multiple third switches K3. The multiple first switches K1 are respectively connected between the first live wire connector L1 and multiple socket units 20a of the first socket module 201. The multiple second switches K2 are respectively connected between the second live wire connector L2 and multiple socket units 20a of the second socket module 202. The multiple third switches K3 are respectively connected between the third live wire connector L3 and multiple socket units 20a of the third socket module 203.

[0034] In this configuration, multiple first switches K1 are correspondingly arranged with multiple socket units 20a in the first socket module 201, and each first switch K1 has an on state and an off state. For each first switch K1, when the first switch K1 is in the on state, the first switch K1 can control the power signal from the first live wire connector L1 to be supplied to the corresponding socket unit 20a in the first socket module 201. The power supply formed by the connection module 10, the first live wire connector L1, the first switches K1, and the corresponding socket units 20a in the first socket module 201 is thus connected. When the circuit is open, the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. For each first switch K1, when the first switch K1 is in the off state, the first switch K1 cannot control the power signal from the first live wire connector L1 to be supplied to the corresponding socket unit 20a in the first socket module 201. The power supply branch formed by the connection module 10, the first live wire connector L1, the first switch K1 and the corresponding socket unit 20a in the first socket module 201 is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0035] Multiple second switches K2 and multiple socket units 20a in the second socket module 202 are configured one-to-one, and each second switch K2 has an on state and an off state. For each second switch K2, when the second switch K2 is in the on state, the second switch K2 can control the power signal from the second live wire connector L2 to be provided to the corresponding socket unit 20a in the second socket module 202, thus connecting the power supply branch formed by the connection module 10, the second live wire connector L2, the second switch K2, and the corresponding socket unit 20a in the second socket module 202. When the circuit is open, the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. For each second switch K2, when the second switch K2 is in the off state, the second switch K2 cannot control the power signal from the second live wire connector L2 to be supplied to the corresponding socket unit 20a in the second socket module 202. The power supply branch formed by the connection module 10, the second live wire connector L2, the second switch K2, and the corresponding socket unit 20a in the second socket module 202 is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0036] Multiple third switches K3 and multiple socket units 20a in the third socket module 203 are configured in a one-to-one correspondence, and each third switch K3 has an on state and an off state. For each third switch K3, when the third switch K3 is in the on state, the third switch K3 can control the power signal from the third live wire connector L3 to be provided to the corresponding socket unit 20a in the third socket module 203, thus connecting the power supply branch formed by the connection module 10, the third live wire connector L3, the third switch K3 and the corresponding socket unit 20a in the third socket module 203. When the circuit is open, power unit 2 can supply power to external devices through rack-mounted power distribution unit 1. For each third switch K3, when the third switch K3 is in the off state, the third switch K3 cannot control the power signal from the third live wire connector L3 to be supplied to the corresponding socket unit 20a in the third socket module 203. The power supply branch formed by the connection module 10, the third live wire connector L3, the third switch K3 and the corresponding socket unit 20a in the third socket module 203 is disconnected, and power unit 2 cannot supply power to external devices through rack-mounted power distribution unit 1.

[0037] Specifically, the specific forms and settings of the first switch K1, the second switch K2, and the third switch K3 may include, but are not limited to, one or more of the following situations.

[0038] In the first scenario, at least one of the first switch K1, the second switch K2, and the third switch K3 is a hydraulic switch. The hydraulic switch can be, but is not limited to, a hydraulic electromagnetic circuit breaker; the specific model of the hydraulic switch is not limited here, and designers can make a reasonable selection based on actual needs. When the current in the power supply branch is within the normal operating current range, the hydraulic switch is in the conducting state. At this time, the power supply branch formed by the corresponding socket unit 20a in the connecting module 10, the first live wire connector L1 (or the second live wire connector L2 or the third live wire connector L3), the first switch K1 (or the second switch K2 or the third switch K3), and the first socket module 201 (or the second socket module 202 or the third socket module 203) is connected, and the power supply unit 2 can supply power to external equipment through the rack-mounted power distribution unit 1. When the current in the power supply branch exceeds the normal operating current range, the hydraulic switch is in the off state. At this time, the power supply branch formed by the corresponding socket unit 20a in the connection module 10, the first live wire connector L1 (or the second live wire connector L2 or the third live wire connector L3), the first switch K1 (or the second switch K2 or the third switch K3), and the first socket module 201 (or the second socket module 202 or the third socket module 203) is disconnected, and the power supply unit 2 cannot supply power to external equipment through the rack-mounted power distribution unit 1. Of course, in other cases, the first switch K1, the second switch K2, and the third switch K3 can also be mechanical electromagnetic circuit breakers, etc.

[0039] In the second scenario, at least one of the first switch K1, the second switch K2, and the third switch K3 is used to close when an overload is detected in the power supply branch, thereby stopping the corresponding socket unit 20a from supplying power to external devices. At least one of the first switch K1, the second switch K2, and the third switch K3 is also used to be in the aforementioned off state when the current in the power supply branch is detected to exceed the normal operating current range, thereby disconnecting the power supply branch and preventing the power supply unit 2 from supplying power to external devices through the rack-mounted power distribution unit 1.

[0040] In the third scenario, at least one of the first switch K1, the second switch K2, and the third switch K3 is used to open or close under user operation. The user can press the first switch K1 (and / or the second switch K2 and / or the third switch K3) to switch between the aforementioned on and off states. When the current in the power supply branch exceeds the normal operating current range, the first switch K1 (and / or the second switch K2 and / or the third switch K3) can automatically switch from the on state to the off state to achieve overcurrent protection.

[0041] By designing the first live wire connector L1, the first switch K1, and the first socket module 201, a separate power supply branch is formed by connecting the module 10, the first live wire connector L1, the first switch K1, and the corresponding socket unit 20a in the first socket module 201. By designing the second live wire connector L2, the second switch K2, and the second socket module 202, a separate power supply branch is formed by connecting the module 10, the second live wire connector L2, the second switch K2, and the corresponding socket unit 20a in the second socket module 202. By designing the third live wire connector L3, the third switch K3, and the third socket module 203, a separate power supply branch is formed by connecting the module 10, the third live wire connector L3, the third switch K3, and the corresponding socket unit 20a in the third socket module 203. The three power supply branches do not interfere with each other. When the current in one of the power supply branches exceeds the normal operating current range, it is only necessary to disconnect that power supply branch, and the remaining power supply branches can still operate normally.

[0042] It should be noted that the overcurrent protection on the power supply branch where the first switch K1, the second switch K2, and the third switch K3 are located is achieved by the characteristics of the switches themselves and is not related to the intelligent monitoring side. For example, when the current in the power supply branch exceeds the normal operating current, the user can manually switch the first switch K1 / second switch K2 / third switch K3 from the on state to the off state as needed. Alternatively, the first switch K1 / second switch K2 / third switch K3 can also automatically switch from the on state to the off state.

[0043] like Figure 1 As shown, the connection module 10 includes a connector 11, which is a five-wire three-phase industrial connector 11. The connection module 10 also includes a power board (not shown in the figure), the connector 11 is connected to the power board via a cable 12, and the power board is also connected to the connection component 30 to provide a power signal to the connection component 30.

[0044] The first live wire connector L1, the second live wire connector L2, the third live wire connector L3, the neutral wire connector N, and the ground wire connector PE are all made of copper strips. The first switch K1, the second switch K2, and the third switch K3 are soldered between their respective connectors and the socket module 20. The neutral wire connector N and the ground wire connector PE are also connected to the socket module 20. Copper has good conductivity. The first switch K1 is soldered between the first live wire connector L1 and the first socket module 201, the second switch K2 is soldered between the second live wire connector L2 and the second socket module 202, and the third switch K3 is soldered between the third live wire connector L3 and the third socket module 203.

[0045] like Figure 1 and Figure 5 As shown, the rack-mounted power distribution unit 1 also includes a rack housing 50, which extends along a predetermined direction. A power board is connected to one end of the rack housing 50. A first switch K1, a first socket module 201, a second switch K2, a second socket module 202, a third switch K3, and a third socket module 203 are arranged sequentially along the extending direction of the rack housing 50. This arrangement neatly places the first switch K1, first socket module 201, second switch K2, second socket module 202, third switch K3, and third socket module 203 on the rack housing 50, facilitating wiring.

[0046] The socket unit 20a includes a first socket 20b and a second socket 20c. Multiple first sockets 20b and multiple second sockets 20c in the first socket module 201, the second socket module 202, and the third socket module 203 are arranged in at least two rows along the extending direction of the rack housing 50. Multiple first sockets 20b are arranged in one of the at least two rows, and multiple second sockets 20c are arranged in the other of the at least two rows. In this embodiment, multiple first sockets 20b and multiple second sockets 20c in the first socket module 201, the second socket module 202, and the third socket module 203 are arranged in two rows along the extending direction of the rack housing 50, with all first sockets 20b arranged in one row and all second sockets 20c arranged in the other row.

[0047] Specifically, for the first socket module 201, each socket unit 20a in the first socket module 201 may include a first socket 20b and a second socket 20c. In this case, each first switch K1 is connected to the first live wire connector L1 and the corresponding first socket 20b of the socket unit 20a, and each first switch K1 is also connected to the first live wire connector L1 and the corresponding second socket 20c of the socket unit 20a. Each socket unit 20a in the first socket module 201 may also include multiple (two or more) first sockets 20b and multiple (two or more) second sockets 20c. In this case, each first switch K1 is connected to the first live wire connector L1 and the multiple first sockets 20b of the corresponding socket unit 20a, and each first switch K1 is also connected to the first live wire connector L1 and the multiple second sockets 20c of the corresponding socket unit 20a.

[0048] Regarding the second socket module 202, each socket unit 20a in the second socket module 202 may include a first socket 20b and a second socket 20c. In this case, each second switch K2 is connected to the second live wire connector L2 and the corresponding first socket 20b of the socket unit 20a, and each second switch K2 is also connected to the second live wire connector L2 and the corresponding second socket 20c of the socket unit 20a. Each socket unit 20a in the second socket module 202 may also include multiple (two or more) first sockets 20b and multiple (two or more) second sockets 20c. In this case, each second switch K2 is connected to the second live wire connector L2 and the multiple first sockets 20b of the corresponding socket unit 20a, and each second switch K2 is also connected to the second live wire connector L2 and the multiple second sockets 20c of the corresponding socket unit 20a.

[0049] Regarding the third socket module 203, each socket unit 20a in the third socket module 203 may include a first socket 20b and a second socket 20c. In this case, each third switch K3 is connected to the third live wire connector L3 and the corresponding first socket 20b of the socket unit 20a, and each third switch K3 is also connected to the third live wire connector L3 and the corresponding second socket 20c of the socket unit 20a. Each socket unit 20a in the third socket module 203 may also include multiple (two or more) first sockets 20b and multiple (two or more) second sockets 20c. In this case, each third switch K3 is connected to the third live wire connector L3 and the multiple first sockets 20b of the corresponding socket unit 20a, and each third switch K3 is also connected to the third live wire connector L3 and the multiple second sockets 20c of the corresponding socket unit 20a.

[0050] Specifically, the specific type and other details of the design of the first socket 20b and the second socket 20c may include, but are not limited to, one or more of the following:

[0051] In the first scenario, the first socket 20b is a C13 socket. A C13 socket is a power outlet interface that conforms to the IEC 60320 standard and can be used, but is not limited to, for connecting computers, servers, network equipment, and some household appliances.

[0052] In the second case, the maximum current of the first socket 20b is 10A.

[0053] In the third case, the second socket 20c is a hybrid socket. The hybrid socket (i.e., the C39 socket) is a special power socket interface, mainly used in high-power power distribution units (PDUs) in data centers and server rooms.

[0054] In the fourth case, when both the first socket 20b and the second socket 20c are connected to external devices, the maximum total current flowing through the first socket 10b and the second socket 20c is 16A.

[0055] like Figure 6 and Figure 7 As shown, the rack-mounted power distribution unit 1 also includes a fixing structure 60 disposed on the rack housing 50, which is used to fix the rack housing 50 to the server rack. The specific design of the fixing structure 60 may include, but is not limited to, one or more of the following situations.

[0056] In the first scenario, the fixing structure 60 includes a first fixing structure 61 and a second fixing structure 62 located at the end of the rack housing 50 away from the connector 11. The first fixing structure 61 includes at least one hanging hole, and the second fixing structure 62 includes at least one screw fixing structure. The server rack is provided with hooks corresponding to the hanging holes, and the hooks are hooked onto the hanging holes. The server rack is provided with threaded holes corresponding to the screw fixing structures (i.e., through holes for screws to pass through), and the screws pass through the screw fixing structures and connect to the threaded holes. By designing the first fixing structure 61 and the second fixing structure 62, the installation between the rack-mounted power distribution unit 1 and the server rack is facilitated.

[0057] In the second scenario, the rack housing 50 has a front side where the socket module 20 is located and a rear side opposite to the front side. The fixing structure 60 also includes a third fixing structure 63 located on the rear side, which is also used to fix the rack housing 50 to the server rack. For example, the third fixing structure 63 can be another screw fixing structure (i.e., another through hole for another screw to pass through), in which case the other screw passes through the other screw fixing structure and is threadedly connected to another threaded hole on the server rack; another example is that the third fixing structure 63 can also be a snap-fit ​​fixing structure (i.e., a through hole for a snap-fit ​​pin to pass through), in which case the snap-fit ​​pin passes through the snap-fit ​​fixing structure and engages with a snap-fit ​​hole on the server rack; yet another example is that the third fixing structure 63 can also be a pin fixing structure (i.e., another through hole for a pin to pass through), in which case the pin passes through the pin fixing structure and engages with a socket on the server rack. By designing the third fixing structure 63, the installation between the rack-mounted power distribution unit 1 and the server rack can be realized. It should be noted that the first fixing structure 61, the second fixing structure 62 and the third fixing structure 63 cooperate with each other to realize multiple installations between the rack-mounted power distribution unit 1 and the server rack, which can effectively improve the installation stability between the rack-mounted power distribution unit 1 and the server rack.

[0058] like Figure 1 and Figure 8 As shown, the rack-mounted power distribution unit 1 also includes a central control module 70. The central control module 70 is installed on the rack housing 50 and connected to the connection component 30 to obtain power signals. The central control module 70 is located between the first socket module 201 and the second switch K2, or the central control module 70 is located between the second socket module 202 and the third switch K3.

[0059] The specific installation method between the central control module 70 and the rack housing 50 is not limited here, and the designer can make reasonable designs according to actual needs. For example, the central control module 70 can be detachably connected to the rack housing 50 by at least one of the following methods: screw connection, snap connection or plug connection. Alternatively, the central control module 70 can be non-detachably connected to the rack housing 50 by riveting or gluing.

[0060] Specifically, the central control module 70 includes a main circuit board 71, a display screen 72, control buttons 73, and a communication port 74. The display screen, control buttons 73, and communication port 74 are mounted on the main circuit board 71. The detailed design of the control buttons 73, communication port 74, and other detailed designs of the central control module 70 may include, but is not limited to, one or more of the following situations.

[0061] In the first scenario, the control button 73 includes a reset button 73a and a function button 73b. The reset button 73a is used to reset the system; the function button 73b is used to execute predetermined control functions such as entering the system menu, scrolling through the menu, and confirming the function.

[0062] In the second scenario, the central control module 70 also includes a communication circuit board 75 and a port circuit board 76. The communication circuit board 75 and port circuit board 76 are mounted on the main circuit board 71, and the communication port 74 is located on the port circuit board 76. The communication port 74 includes at least one of a sensor port 74a, a serial port 74b, a USB port 74c, a data port 74d, and a network port 74e. Both the communication circuit board 75 and the port circuit board 76 are electrically connected to the main circuit board 71. The antenna and communication chip in the central control module 70 can be located on the communication circuit board 75. By designing the main circuit board 71, communication circuit board 75, and port circuit board 76 as separate components, interference between devices integrated on each circuit board can be effectively reduced, and the manufacturing process is simpler and less expensive. It should be noted that the sensor port 74a is a temperature sensor port, used for communication with a temperature sensor (not shown in the figure) installed on the server rack. The temperature sensor can be used to detect the actual temperature of the server rack where the rack-mounted power distribution unit 1 is located. When the actual temperature detected by the temperature sensor does not exceed the preset temperature threshold, the display screen 72 can be used to display the actual temperature. When the actual temperature detected by the temperature sensor exceeds the preset temperature threshold, an alarm signal will be generated. The controller of the central control module 70 can control the display screen 72 to make a text warning prompt based on the alarm signal. At the same time, the alarm information can be sent through the external communication port.
