Definitions
- This invention relates generally to the field of communications and more particularly to an integrated connector unit.
- a communications switch such as an ethernet switch, allows a plurality of communications devices to communicate with one another.
- a connector may be coupled to the printed circuit board (“PCB”) of the communications switch so that the communications device may plug into the connector.
- PCB printed circuit board
- a connector is also referred to as a “jack.”
- the communication device may also receive power from the jack.
- Providing power through the jack eliminates the need for the communications device to have a separate power source, such as an AC/DC power source. Power provided through the jack is referred to as “inline power.”
- Jacks are sometimes manufactured as a jack unit that includes in its housing one or more jacks and some of the components for carrying data.
- isolation transformers for the data lines may be included in the housing of a jack unit.
- the pins of a jack unit may be soldered onto the PCB to electrically couple the data components in the housing of jack unit to the appropriate components of the PCB.
- Including some of the components for carrying data in the housing saves board space on the PCB.
- positioning the isolation transformers in the housing of the jack unit may not allow inline power to be provided to the communications devices that plug into the jack unit. This is because the jack side of the isolation transformer, which must be accessible to provide inline power, is blocked by the housing of the jack unit. Thus, inline power may not be available where the isolation transformers are included in a jack unit.
- an integrated jack unit includes a housing.
- the integrated jack unit also includes a jack positioned at least in part in the housing.
- the integrated jack unit also includes a power controller positioned in the housing and coupled to the jack by a line.
- the line is designated for coupling with a transformer.
- the integrated jack unit also includes a pin protruding outwardly from the housing. The pin is electrically coupled to the jack through the power controller and the line. The pin is positioned to receive power for the jack from a printed circuit board.
- inline power may be provided through integrated jack units.
- design of a main printed circuit board is simplified without substantially complicating the design of the jack unit.
- overall manufacturing process of networking equipment is simplified because jack units having integrated isolation transformers may be used for both Ethernet, non-Ethernet, standard Ethernet, and inline Ethernet applications.
- a same printed circuit board design may be used for both standard and inline powered systems because the inline power circuitry is in the jack unit.

- System 10 comprises network segments 18 A through 18 C that are coupled to each other over a communications network 24 and/or a communications switch 14 .
- Network segments 18 A through 18 C are jointly referred to as network segments 18 .
- network segment 18 A is coupled to network segment 18 B over communications switch 14 .
- Network segment 18 C is coupled to network segments 18 A and 18 B over communications network 24 and communications switch 14 . More or less network segments 18 may be coupled to each other over communications network 24 and communications switch 14 .
- Network segments 18 A through 18 C each comprises one or more communications devices 20 .
- a jack unit 30 is coupled to communications switch 14 to provide one or more ports (not explicitly shown) that may be used to physically connect communications devices 20 .
- a cable having plugs may be used to plug in communications devices 20 to jack unit 30 .
- switch 14 and network segments 18 may be devices that are capable of operating according to the ethernet network standard.
- Communications switch 14 may be operable to send and receive packets to and from communications devices 20 according to the addresses of the packets. Upon receiving one or more packets from device 20 , switch 14 sends the received packets to a particular communications device 20 that is identified by the included address. Switch 14 may send and receive the packets over network 24 , jack unit 30 , or any other suitable conduit or a combination of conduits that couples switch 14 to communications devices 20 . In some examples, a hub, a router, or any other suitable device may be used instead of switch 14 . Communications device 20 may be any communications device that is operable to communicate with other communications devices over a network architecture. Examples of communications device 20 include a Voice over Internet Protocol (“VoIP”) phone and a computer.
- VoIP Voice over Internet Protocol
- Jack unit 30 may comprise one or more RJ-45 jacks; however, jack unit 30 may comprise other types of jacks. Where jack unit 30 comprises RJ-45 jacks, communications devices 20 may plug into jack unit 30 using cables having plugs that are adaptable to a RJ-45 jack. Jack unit 30 may also comprise one or more isolation transformers within its housing. A jack unit having isolation transformers within its housing is referred to as a “mag jack.” Thus, jack unit 30 may also be referred to as mag jack 30 .
- An isolation transformer is a transformer that is operable to protect the components of switch 14 , such as integrated circuit chips, against excessive common mode voltages from communications devices 20 and/or cables attaching devices 20 to switch 14 .
- Mag jack 30 generally includes outwardly disposed pins that may be soldered onto the appropriate apertures of a printed circuit board of communications switch 14 , thereby electrically coupling the components of mag jack 30 to the components of communications switch 14 .
- the use of mag jack 30 saves space on the main printed circuit board (“PCB”) of switch 14 because the isolation transformers are in mag jack 30 rather than on the PCB.
- communications device 20 may establish a physical connection with switch 14 . To that end, communications device 20 may plug into mag jack 30 . Along with a physical connection to switch 14 , communications device 20 may also require access to power in order to send and receive packets to and from switch 14 .
- Power may be provided to communications device 20 in a variety of ways. For example, alternating current (“AC”) power may be provided to communications device 20 by plugging communications device 20 into a wall socket. In another example, communications device 20 may receive direct current (“DC”) power from a battery pack. Power may also be provided inline, which refers to transmitting power from switch 14 to communications device 20 over a jack unit and the physical cable that plugs into the jack unit.
- AC alternating current
- DC direct current
- Power may also be provided inline, which refers to transmitting power from switch 14 to communications device 20 over a jack unit and the physical cable that plugs into the jack unit.
- inline power is conventionally not provided for communications devices 20 plugged into a mag jack because the housing of the mag jack that integrates the isolation transformers to the jack unit also prevents a designer from injecting power into the side of the transformer that is electrically coupled to a jack of the mag jack. If inline power is not provided to the jack-side of the isolation transformer, then DC power is required to travel across the isolation transformer to reach the jack and thus is blocked by the isolation transformer. Also, AC line power may not pass readily across the isolation transformer. In some situations, it may be difficult for a designer to simply add a pin to a mag jack to access the jack side of the isolation transformer 30 for power injection because the proximity of the pins may cause an arcing of the power current. Thus, conventionally, the benefits of inline power are not available for a mag jack.
- an apparatus and method are provided that allow inline power to be provided for a mag jack by positioning a power controller within the mag jack. Additional details of example embodiments of the invention are described in greater detail below in conjunction with portions of FIG. 1 and FIGS. 2A through 4 .
- a power controller that controls inline power is positioned in mag jack 30 along with one or more isolation transformers.
- a power converter that supplies the inline power is also positioned in mag jack 30 . Because the power controller is in the housing of mag jack 30 , inline power may be injected into the jack side of the isolation transformer to provide inline power for the jacks of mag jack 30 .
- a mag jack having a power controller in its housing is referred to as an “integrated inline power mag jack” or an “power mag jack.” As such, mag jack 30 is referred to from hereinafter as power mag jack 30 .
- FIG. 2A is a schematic diagram illustrating one embodiment of power mag jack 30 of FIG. 1
- FIG. 2B is a perspective view of one embodiment of power mag jack 30 of FIG. 2A
- FIGS. 2A and 2B are described jointly.
- Power mag jack 30 comprises a housing 70 (shown on FIG. 2B as well). Housing 70 defines power mag jack 30 as a separate component separate from a PCB 110 .
- power mag jack 30 is a device that is separate from PCB 110 that may be added or removed from PCB 110 as a single component of PCB 110 .
- PCB 110 is also referred to as motherboard 110 . Referring back to FIG.
- a jack 74 defining a receiving cavity 76 is positioned at least in part in housing 70 .
- an isolation transformer set 78 having at least two transformers 78 A and 78 B is positioned within housing 70 and coupled to jack 74 through lines 82 and 84 . Because lines 82 and 84 couple isolation transformer set 78 to jack 74 , lines 82 and 84 are also referred to as “jack side” lines 82 and 84 . In some embodiments, more than one jack 74 may be included in power mag jack 30 .
- the number of components that support jack 74 may be increased to support the additional jacks 74 .
- all of jacks 74 and their supporting components are packaged as a single component within housing 70 .
- lines 82 couple transformer 78 A to a data transmission portion 88 of jack 74 .
- Data transmission portion 88 is used for outgoing packets.
- Lines 84 couple transformer 78 B to a data receive portion 90 of jack 74 .
- Data receive portion 90 is used for incoming packets.
- lines 86 A and 86 B are coupled to respective center taps 80 A and 80 B of transformers 78 A and 78 B. Lines 86 A and 86 B are operable to carry inline power for jack 74 without going through transformer set 78 so that inline power may be available for communications devices 20 , which may be plugged into jack 74 .
- lines 86 A and 86 B are terminated by a termination 94 prior to reaching jack 74 .
- a termination 94 is a load that is positioned within housing 70 and used to minimize common node noise.
- termination 94 may comprise one or more DC blocking capacitors 98 . In one embodiment, three or fewer DC blocking capacitors 98 may be used.
- a BOB SMITH termination may be used as termination 94 ; however, any other suitable termination may be used as termination 94 .
- a power controller 100 is positioned in housing 70 of power mag jack 30 to provide inline power.
- power controller 100 is coupled to center tap 80 A through a power switch 102 and line 86 A; however, in some embodiments, power controller 100 may be coupled to center tap 80 B through power switch 102 and line 86 B.
- Positioning power controller 100 in housing 70 of power mag jack 30 rather than on motherboard 110 of switch 14 (shown in FIG. 1 ) is advantageous in some embodiments of the invention for the following reason. Because power controller 100 is inside of housing 70 , power controller 100 is not physically prevented by housing 70 from physically coupling to one or more of jack side lines 86 A or 86 B.
- power controller 100 may provide inline power to jack 74 .
- manufacturing power controller 100 as a part of power mag jack 30 allows a designer to benefit from the advantages of integrating isolation transformers into a jack unit and the advantages of providing inline power to communications device 20 .
- isolation transformer set 78 may not be included in housing 70 .
- Power controller 100 may be positioned within housing 70 that does not include isolation transformer set 78 . This is advantageous in some embodiments because, regardless of the type of jack unit, a printed circuit board receiving the jack unit may be manufactured using a same design because the circuitry for controlling inline power, if any, would be in the jack unit and not on the printed circuit board.
- Power mag jack 30 may be coupled to PCB 110 by soldering connectors 104 to their corresponding apertures 114 (shown in FIG. 2B ) of PCB 110 .
- Connectors 104 are also referred to herein as pins 104 .
- a “pin” refers to any type of connector, such as an edge connector or a mating connector.

- physical device 118 is an ethernet physical layer transceiver 118 .
- Physical device 118 may be operable to perform a variety of functions associated with communication depending on the network standard being used. For example, if physical device 118 were an ethernet physical device 118 , ethernet physical device 118 may perform some or all of the layer one functions, such as packeting TCP/IP packets received from communications device 20 over isolation transformer set 78 into ethernet packets.
- PCB 110 may also include a power converter 120 that may be coupled to a power source 124 .

Description
- This application is a continuation of U.S. application Ser. No. 10/326,236 filed Dec. 20, 2002 and entitled “Integrated Connector Unit”, now U.S. Pat. No. 7,026,730.
- This invention relates generally to the field of communications and more particularly to an integrated connector unit.
- A communications switch, such as an ethernet switch, allows a plurality of communications devices to communicate with one another. To establish a conduit for data between the communications switch and the communications device, a connector may be coupled to the printed circuit board (“PCB”) of the communications switch so that the communications device may plug into the connector. A connector is also referred to as a “jack.” Where possible, the communication device may also receive power from the jack. Providing power through the jack eliminates the need for the communications device to have a separate power source, such as an AC/DC power source. Power provided through the jack is referred to as “inline power.”
- Jacks are sometimes manufactured as a jack unit that includes in its housing one or more jacks and some of the components for carrying data. For example, isolation transformers for the data lines may be included in the housing of a jack unit. The pins of a jack unit may be soldered onto the PCB to electrically couple the data components in the housing of jack unit to the appropriate components of the PCB. Including some of the components for carrying data in the housing saves board space on the PCB. However, positioning the isolation transformers in the housing of the jack unit may not allow inline power to be provided to the communications devices that plug into the jack unit. This is because the jack side of the isolation transformer, which must be accessible to provide inline power, is blocked by the housing of the jack unit. Thus, inline power may not be available where the isolation transformers are included in a jack unit.
- According to one embodiment of the invention, an integrated jack unit is provided. The integrated jack unit includes a housing. The integrated jack unit also includes a jack positioned at least in part in the housing. The integrated jack unit also includes a power controller positioned in the housing and coupled to the jack by a line. The line is designated for coupling with a transformer. The integrated jack unit also includes a pin protruding outwardly from the housing. The pin is electrically coupled to the jack through the power controller and the line. The pin is positioned to receive power for the jack from a printed circuit board.
- Some embodiments of the invention provide numerous technical advantages. Some embodiments may benefit from some, none, or all of these advantages. For example, according to one embodiment, inline power may be provided through integrated jack units. According to another embodiment, the design of a main printed circuit board is simplified without substantially complicating the design of the jack unit. According to another embodiment, the overall manufacturing process of networking equipment is simplified because jack units having integrated isolation transformers may be used for both Ethernet, non-Ethernet, standard Ethernet, and inline Ethernet applications. According to another embodiment, a same printed circuit board design may be used for both standard and inline powered systems because the inline power circuitry is in the jack unit.
- Other technical advantages may be readily ascertained by one of skill in the art.
- Reference is now made to the following description taken in conjunction with the accompanying drawings, wherein like reference numbers represent like parts, in which:
-
FIG. 1 is a schematic diagram illustrating one embodiment of a communications system that may benefit from the teachings of the present invention; -

FIG. 3 is a bottom view of one embodiment of the integrated jack unit ofFIG. 2B ; and -
FIG. 4 is a flow chart illustrating one embodiment of a method of providing inline power through one embodiment of the integrated jack unit ofFIG. 2A . - Embodiments of the invention are best understood by referring to
FIGS. 1 through 4 of the drawings, like numerals being used for like and corresponding parts of the various drawings. -
FIG. 1 is a schematic diagram illustrating one embodiment of acommunications system 10 that may benefit from the teachings of the present invention.System 10 comprisesnetwork segments 18A through 18C that are coupled to each other over acommunications network 24 and/or acommunications switch 14.Network segments 18A through 18C are jointly referred to asnetwork segments 18. As shown inFIG. 1 ,network segment 18A is coupled tonetwork segment 18B overcommunications switch 14.Network segment 18C is coupled tonetwork segments communications network 24 andcommunications switch 14. More orless network segments 18 may be coupled to each other overcommunications network 24 andcommunications switch 14. -
Network segments 18A through 18C each comprises one ormore communications devices 20. Ajack unit 30 is coupled tocommunications switch 14 to provide one or more ports (not explicitly shown) that may be used to physically connectcommunications devices 20. For example, a cable having plugs may be used to plug incommunications devices 20 tojack unit 30. In some embodiments,switch 14 andnetwork segments 18 may be devices that are capable of operating according to the ethernet network standard. -
Communications switch 14 may be operable to send and receive packets to and fromcommunications devices 20 according to the addresses of the packets. Upon receiving one or more packets fromdevice 20,switch 14 sends the received packets to aparticular communications device 20 that is identified by the included address. Switch 14 may send and receive the packets overnetwork 24,jack unit 30, or any other suitable conduit or a combination of conduits that couples switch 14 tocommunications devices 20. In some examples, a hub, a router, or any other suitable device may be used instead of switch 14.Communications device 20 may be any communications device that is operable to communicate with other communications devices over a network architecture. Examples ofcommunications device 20 include a Voice over Internet Protocol (“VoIP”) phone and a computer. -
Jack unit 30 may comprise one or more RJ-45 jacks; however,jack unit 30 may comprise other types of jacks. Wherejack unit 30 comprises RJ-45 jacks,communications devices 20 may plug intojack unit 30 using cables having plugs that are adaptable to a RJ-45 jack.Jack unit 30 may also comprise one or more isolation transformers within its housing. A jack unit having isolation transformers within its housing is referred to as a “mag jack.” Thus,jack unit 30 may also be referred to asmag jack 30. An isolation transformer is a transformer that is operable to protect the components ofswitch 14, such as integrated circuit chips, against excessive common mode voltages fromcommunications devices 20 and/orcables attaching devices 20 to switch 14.Mag jack 30 generally includes outwardly disposed pins that may be soldered onto the appropriate apertures of a printed circuit board of communications switch 14, thereby electrically coupling the components ofmag jack 30 to the components of communications switch 14. The use ofmag jack 30 saves space on the main printed circuit board (“PCB”) ofswitch 14 because the isolation transformers are inmag jack 30 rather than on the PCB. - To send and receive packets from
switch 14,communications device 20 may establish a physical connection withswitch 14. To that end,communications device 20 may plug intomag jack 30. Along with a physical connection to switch 14,communications device 20 may also require access to power in order to send and receive packets to and fromswitch 14. Power may be provided tocommunications device 20 in a variety of ways. For example, alternating current (“AC”) power may be provided tocommunications device 20 by pluggingcommunications device 20 into a wall socket. In another example,communications device 20 may receive direct current (“DC”) power from a battery pack. Power may also be provided inline, which refers to transmitting power fromswitch 14 tocommunications device 20 over a jack unit and the physical cable that plugs into the jack unit. One advantage of providing inline power tocommunications device 20 is that it eliminates the need to provide a separate power source fordevice 20 at the physical location ofdevice 20. Providing inline power also simplifies the design and configuration ofcommunications device 20. - However, inline power is conventionally not provided for
communications devices 20 plugged into a mag jack because the housing of the mag jack that integrates the isolation transformers to the jack unit also prevents a designer from injecting power into the side of the transformer that is electrically coupled to a jack of the mag jack. If inline power is not provided to the jack-side of the isolation transformer, then DC power is required to travel across the isolation transformer to reach the jack and thus is blocked by the isolation transformer. Also, AC line power may not pass readily across the isolation transformer. In some situations, it may be difficult for a designer to simply add a pin to a mag jack to access the jack side of theisolation transformer 30 for power injection because the proximity of the pins may cause an arcing of the power current. Thus, conventionally, the benefits of inline power are not available for a mag jack. - According to some embodiments of the present invention, an apparatus and method are provided that allow inline power to be provided for a mag jack by positioning a power controller within the mag jack. Additional details of example embodiments of the invention are described in greater detail below in conjunction with portions of
FIG. 1 andFIGS. 2A through 4 . - Referring back to
FIG. 1 , in one embodiment of the invention, a power controller that controls inline power is positioned inmag jack 30 along with one or more isolation transformers. In another embodiment, a power converter that supplies the inline power is also positioned inmag jack 30. Because the power controller is in the housing ofmag jack 30, inline power may be injected into the jack side of the isolation transformer to provide inline power for the jacks ofmag jack 30. A mag jack having a power controller in its housing is referred to as an “integrated inline power mag jack” or an “power mag jack.” As such,mag jack 30 is referred to from hereinafter aspower mag jack 30. -
FIG. 2A is a schematic diagram illustrating one embodiment ofpower mag jack 30 ofFIG. 1 , andFIG. 2B is a perspective view of one embodiment ofpower mag jack 30 ofFIG. 2A .FIGS. 2A and 2B are described jointly.Power mag jack 30 comprises a housing 70 (shown onFIG. 2B as well).Housing 70 definespower mag jack 30 as a separate component separate from aPCB 110. As shown inFIG. 2B ,power mag jack 30 is a device that is separate fromPCB 110 that may be added or removed fromPCB 110 as a single component ofPCB 110.PCB 110 is also referred to asmotherboard 110. Referring back toFIG. 2A , ajack 74 defining a receivingcavity 76 is positioned at least in part inhousing 70. In one embodiment, an isolation transformer set 78 having at least twotransformers housing 70 and coupled to jack 74 throughlines lines lines lines jack 74 may be included inpower mag jack 30. In such embodiments, the number of components that supportjack 74, such as the number oftransformers jacks 74 inpower mag jack 30, all ofjacks 74 and their supporting components are packaged as a single component withinhousing 70. - In one embodiment, lines 82
couple transformer 78A to adata transmission portion 88 ofjack 74.Data transmission portion 88 is used for outgoing packets.Lines 84couple transformer 78B to a data receiveportion 90 ofjack 74. Data receiveportion 90 is used for incoming packets. In one embodiment,lines transformers Lines jack 74 without going through transformer set 78 so that inline power may be available forcommunications devices 20, which may be plugged intojack 74. In one embodiment,lines termination 94 prior to reachingjack 74. Atermination 94 is a load that is positioned withinhousing 70 and used to minimize common node noise. In one embodiment,termination 94 may comprise one or moreDC blocking capacitors 98. In one embodiment, three or fewerDC blocking capacitors 98 may be used. In some embodiments, a BOB SMITH termination may be used astermination 94; however, any other suitable termination may be used astermination 94. - According to the teachings of the invention, a
power controller 100 is positioned inhousing 70 ofpower mag jack 30 to provide inline power. In one embodiment,power controller 100 is coupled to center tap 80A through apower switch 102 andline 86A; however, in some embodiments,power controller 100 may be coupled tocenter tap 80B throughpower switch 102 andline 86B.Positioning power controller 100 inhousing 70 ofpower mag jack 30 rather than onmotherboard 110 of switch 14 (shown inFIG. 1 ) is advantageous in some embodiments of the invention for the following reason. Becausepower controller 100 is inside ofhousing 70,power controller 100 is not physically prevented by housing 70 from physically coupling to one or more ofjack side lines jack side lines power controller 100 may provide inline power to jack 74. Thus,manufacturing power controller 100 as a part ofpower mag jack 30 allows a designer to benefit from the advantages of integrating isolation transformers into a jack unit and the advantages of providing inline power tocommunications device 20. In some embodiments, isolation transformer set 78 may not be included inhousing 70.Power controller 100 may be positioned withinhousing 70 that does not include isolation transformer set 78. This is advantageous in some embodiments because, regardless of the type of jack unit, a printed circuit board receiving the jack unit may be manufactured using a same design because the circuitry for controlling inline power, if any, would be in the jack unit and not on the printed circuit board. -
Power mag jack 30 may be coupled toPCB 110 by solderingconnectors 104 to their corresponding apertures 114 (shown inFIG. 2B ) ofPCB 110.Connectors 104 are also referred to herein as pins 104. A “pin” refers to any type of connector, such as an edge connector or a mating connector. By couplingpins 104 to theircorresponding apertures 114, the various devices ofpower mag jack 30 are electrically coupled to the appropriate components ofPCB 110. For example, as shown inFIG. 2B , pin 104A may be inserted into aparticular aperture 114 that is connected to one or morephysical devices 118. Becausepin 104A is also coupled to isolation transformer set 78,pin 104A may be used as a data pin that carries data betweenphysical devices 118 ofPCB 110 and isolation transformer set 78. In one embodiment,physical device 118 is an ethernetphysical layer transceiver 118.Physical device 118 may be operable to perform a variety of functions associated with communication depending on the network standard being used. For example, ifphysical device 118 were an ethernetphysical device 118, ethernetphysical device 118 may perform some or all of the layer one functions, such as packeting TCP/IP packets received fromcommunications device 20 over isolation transformer set 78 into ethernet packets.PCB 110 may also include apower converter 120 that may be coupled to apower source 124. In one embodiment, pins 104M and 104N that are coupled to switch 102 andcenter tap 80B, respectively, may be inserted intoparticular apertures 114 that are connected topower converter 120 ofPCB 110. - In one embodiment, a
power converter 108 may also be positioned inpower mag jack 30. This is advantageous in some embodiments because of the resulting savings in board space onmotherboard 110. AlthoughFIG. 2A showspower converter 108 positioned inhousing 70,power converter 108 may also be position outside ofhousing 70 and onmotherboard 110 as a separate component. In such embodiments, DC power having 48 volts may be received from anoutside power converter 108 through one or more ofpins 104, such aspins power mag jack 30 is coupled tomotherboard 110,pin 104M may be used to receive power and carry that power topower switch 102 controlled bypower controller 100 or directly topower controller 100. In one embodiment,power switch 102 is a simple on/off switch; however, a variable resistance element may be used aspower switch 102. In one embodiment,power converter 108 is operable to receive AC power and provide DC power forpower switch 102. In one embodiment,power converter 108 is operable to provide DC power having a level of 48 volts. In one embodiment, somepins 104 may be used to couple different devices inpower mag jack 30 to other appropriate portions ofmotherboard 110. In one embodiment, power may be provided to ethernet unused pairs (not explicitly shown) . Such an embodiment does not require isolation transformers. -
FIG. 3 is a bottom view of portions of thepower mag jack 30 illustrated inFIGS. 2A and 2B , showing the placement ofpins 104. As shown inFIG. 3 , one embodiment ofpower mag jack 30 comprisespins 104A through 104N (jointly referred to as pins 104) that are protruding outwardly fromhousing 70 ofpower mag jack 30. In one embodiment,power mag jack 30 may comprisemore pins 104 than conventional jack units because inline power is provided topower mag jack 30. In some embodiments where an ethernet standard is used, pins 104 may serve the following functions:Pin 104A carries an ethernet TX negative pulse.Pin 104B carries an ethernet center tap TX bias.Pin 104C carries an ethernet TX positive pulse.Pins Pin 104F carries an ethernet RX center tap bias.Pin 104G carries an ethernet RX negative pulse.Pin 104H carries an ethernet RX positive pulse. Theextra pins 104 for providing inline power arepins 104I through 104N, in one embodiment.Pin 104I carries serial clock input signals.Pin 104J carries serial data input signals.Pin 104K carries serial clock output signals.Pin 104L carries serial data output signals.Pin 104M is for ethernet power main.Pin 104N is for ethernet power return. Although a particular arrangement ofpins 104 is shown inFIG. 3 , other arrangements ofpin 104 are possible in other embodiments. Further, more orless pins 104 may be used forpower mag jack 30 depending on the design specifications. In one embodiment, distances d1 and d2 referred to byreference numbers 160 and 162, respectively, may be sufficiently wide to lower the probability of arcing betweenpins 104A through 104L andpower pins 104M through 104N. In one embodiment,power converter 108 may comprise an isolation barrier (not explicitly shown) to reduce the distances referred to byreference numbers 160 and 162. Examples of an isolation barrier include a transformer, a capacitor, and an optocoupler. -
