     DETAILED DESCRIPTION 
       [0013]    A computer connector and/or port is a device which may join together various peripheral components to the computer. As such, an electrical component may regulate the connector and/or port to determine when a peripheral electrical device is present in a connector housing. Such peripheral devices include, by way of example, a cable, transceiver, or other type of electrical device. However the electrical component may not be able to detect if a blank insert, such as a plug, is present. Additionally, without detecting the presence of the plug, the computing system may continue to power up and operate hardware components, such as networking switches, which produce much heat. When these networking switches produce heat, the heated airflow may continue to flow out of the computer connector and/or port. As such, fans within the computing system may pull this heated airflow through an open computer connector and/or port, thus producing in an inefficient cooling system. For example, the connector may have a previously installed transceiver, thus when the transceiver is removed, this creates an inefficient airflow by leaving the connector housing open for pulling in heated air. Further, if the hardware components within the computing system are in operation, this may create an electromagnetic field which may produce leakage which may interfere with other components near the open connector. 
         [0014]    To address these issues, examples disclosed herein provide a plug with an electrical contact. The electrical contact interfaces with a connector pin in a connector housing in such a manner that a closed circuit is created upon the interface between the electrical contact and the connector pin. This closed circuit signals to a processor a presence and/or installation of the plug with the connector housing. In this manner, the processor detects the presence of the plug prior to powering up a networking switch. The presence of this plug prior to powering op the networking switch ensures an efficient mechanism in which to cool the networking switch. The plug provides a closed connector in the sense a heated airflow may not he drawn hack through the connector housing to cool the networking switch. Rather, a fan associated with the connector housing may pull air from elsewhere thus enabling cooler air to provided across the networking switch. Installing the plug enables the cooler airflow which helps remedy the heated airflow situation when the transceiver may be removed. 
         [0015]    Additionally, the plug may be installed with the connector housing in such a manner which provides a sealant against the airflow coming in through an open connector housing. This further ensures a proper airflow occurs for cooling the networking switch and other electrical components associated with the connector housing. 
         [0016]    In another example discussed herein, the plug supports an electromagnetic interference (EMI) shield to prevent leaking of an EMI field to other electrical components. In this example, the EMI shield is located on the plug such that when the plug is installed with the connector housing, the EMI shield also aligns with a grounding clip located on the connector housing. The EMI shield, by way of example, consists of a strip of conductive material which connects or interfaces with the grounding clip within the connector housing. The grounding clip may also consist of conductive material which carries the electromagnetic field within the connector housing to ground. As such, placement of the EMI shield in connection with the grounding clip prevents the leakage of the electromagnetic interference which may interfere with other hardware components surrounding the connector housing. 
         [0017]    Referring now to the figures,  FIGS. 1A-1C  illustrate a plug  104  from various perspectives and a connector housing  108  to receive the plug  104 . The plug  104  supports an electrical contact  102  to interface with a connector pin  110  located in a connector housing  108 . The electrical contact  102  interfaces with the connector pin  110  in such a manner that the electrical contact  102  is coupled to the connector pin  110  to create a closed. electrical connection. Creating this closed electrical connection, a processor (not illustrated) electrically connected to the connector housing  108  detects a presence of the plug  104  in the connector housing  108 . The presence of the plug  104  in the connector housing  108  includes an installation of the plug  104  into the connector housing  108  which allows the electrical contact  102  to couple to the connector pin  110 . 
         [0018]      FIG. 1A  illustrates the plug  104  supporting the electrical contact  102  from a rear perspective. The plug  104  is a mechanical structure which supports the electrical contacts  102  and the plug enclosure  106 . In one implementation, the plug  104  supports these components  102  and  106  in such a manner that when the plug  104  is installed in the connector housing  108 , the plug  104  may provide a seal against airflow into an open connector housing  108 . In another implementation, the plug  104  may consist of non-conductive material. The non-conductive material provides an electrical insulation between the connector housing  108  and the environment In this implementation, providing the plug  104  as consisting of non-conductive material enables the plug  104  to couple to the connector housing  108  in such a manner that does not create a flow of power between the connector housing  108  and the plug  104 . This further enables the plug  104  to provide a sealant when coupled with the connector housing  108 . The non-conductive material may include, by way of example, rubber, plastic, glass, composite polymer materials, porcelain, or other type of non-conductive material. Additionally, although  FIGS. 1A-1C  illustrate the plug  104  as supporting the electrical contact  102  and the plug enclosure  106 , this was done for illustrations purposes as the plug  104  may also support an electromagnetic interference (EMI) shield for preventing leakage of electromagnetic fields. 
         [0019]    The electrical contact  102  is a strip of conductive material supported by the plug  104 . The electrical contact  102  couples to the connector pin  110  on the connector housing  108  which creates the closed circuit between the electrical contact  102  and the connector pin  110 . The electrical contact  102  consists of conductive material which enables a flow of current from the connector pin  110  through the electrical contact  102 . In one implementation, upon providing the closed circuit between the electrical contact  102  and the connector pin  110  provides a signal to the processor (not illustrated). This signal indicates the presence and/or installation of the plug  104  with the connector housing  108 . This implementation may be discussed in a later figure. Although  FIGS. 1A-1C  illustrate the electrical contact.  102  as strip of conductive material, this was done for illustration purposes as the electrical contact  102  may include multiple points of conductive material for connecting to the connector pin  110 . 
         [0020]    The plug enclosure  106  provides an overlap of non-conductive material. This overlap may create a sealant so when the plug enclosure  106  is coupled with the connector housing  108 , this prevents a heated airflow from being drawn through the connector housing  108 . This implementation may be discussed in detail in later figures. 
         [0021]      FIG. 1B  illustrates a front perspective of the plug  104  prior to installation into the connector housing  108 . In one implementation, the plug  104  may additionally support a handle  112  which provides control for coupling the plug  104  with the connector housing  108 . 
         [0022]    The handle  112  consists of non-conductive material and is a grip attached to the plug  104  for moving the plug  104  to the connector housing  108 . In one implementation, the handle  112  may consist of a different material than the conductive material from the plug  104 . For example, the plug  104  may consist of rubber while the handle  112  may consist of plastic. 
         [0023]      FIG. 1C  illustrates a front perspective of the connector housing  108 . The connector housing  108  includes the connector pin  110  which interacts with the electrical contact  102  on the backside of the plug  104  as in  FIG. 1 . This interaction enables the processor (not illustrated) electrically connected to the connector pin  110  to detect the presence of the plug  104  with the connector housing  108 . In another implementation, the processor may detect when the plug  104  is absent and/or partially coupled with the connector housing  108 . In this implementation, the plug  104  may he partially installed in the sense the electrical contact  102  does not create the electrical contact with the connector pin  110 . 
         [0024]    The connector housing  108  is an electro-mechanical device which represents a connector and/or port. The connector housing  108  may bring together multiple devices. As such, the connector housing  108  includes the connector and/or port, the structure to support that connector and/or port, and the various electrical connections to other electrical components. The connector housing  108  is considered part of an interconnect module which provides multiple networking switches. In this implementation, the connector housing  108  may be part of a networking system. In another implementation, the connector housing  108  may serve as providing an interface between the networking system and various electrical components, such as transceivers, cables, etc. Additionally, the connector housing  108  may consist of a male-ended or female-ended type of connection. 
         [0025]    The connector pin  110  consists of conductive material which provides the electrical connection between the electrical contact  102  and the networking system. The connector pin  110  serves as sensor pin within the connector housing  108  to indicate to the processor when the plug  104  is installed. Although.  FIG. 1C  illustrates the connector pin  110  as two different pins, this was done for illustration purposes as the connector pin  110  may include a single connector pin and/or multiple connector pins  110 . 
         [0026]      FIGS. 2A-2B  are illustrations from various perspectives of a circuit board  212  and an interconnect module enclosure  214  for supporting multiple connector housings  108 . The interconnect module enclosure  214  is an enclosure over an interconnect module and various networking switches supported by the interconnect module. The multiple connector housings  108  may receive a plug  104  including an electrical contact  102  and an electromagnetic interference (EMI) shield  210 . 
         [0027]      FIG. 2A  illustrates the plug  104  prior to installation into one of the connector housings  108 . Specifically,  FIG. 2A  illustrates a back side perspective of the circuit board  212  including multiple connector housings  108  which may receive the plug  104 . The connector housing  108  may include an air vent opening  209  to expose the heat sink of a transceiver module (not illustrated) when it is installed in the connector housing  108 . The ping  104  includes an electromagnetic interface (EMI) shield  210  and an electrical contact  102  to couple with a connector pin in one of the connector housings  108 . 
         [0028]    The circuit board  212  is a mechanical structure attached to the interconnect module enclosure  214  which supports the multiple connector housings  108  and electrically connects the multiple connector housings  108  to other components. These electrical connections may be illustrated in a later figure. The circuit board  212  is considered part of an interconnect module which provides networking switches for a server. As such, although  FIG. 2A-2B  represents the circuit hoard  212  with the multiple connector housings  108 , this was done for illustration purposes. For example, the circuit board  212  may include a networking switch, a fan in which to cool the networking switch, a processor, a server which responds to various requests across a computer network, and/or other type of networking components. 
         [0029]    The interconnect module enclosure  214  is a mechanical structure which encompasses networking switches which are connected to the multiple connector housings  108 . Although  FIGS. 2A-2B  illustrate part of the interconnect module enclosure  214 , this was done for illustration purposes as the interconnect module enclosure  214  may fully enclose the circuit board  212  and other networking components. 
         [0030]    The EMI shield  210  interacts with a grounding pin as in  FIG. 2B . The grounding clip is located on the connector housing  108  and when coupled with the EMI shield  210 , this prevents an electromagnetic interface (EMI) field leakage. When the grounding clip and the EMI shield  210  are aligned in such a manner that enables these components  210  to ground the EMI field. The EMI field leakage may be generated by the various networking components on the circuit board  212 . As such, the EMI field may cause interference with other networking components. Thus, to prevent much of this interference, the EMI shield and the grounding clip ground the EMI field to prevent much of the EMI field leakage through the multiple connector housings  108 . The EMI shield  210  is a strip of conductive material behind a lip of the plug  104 . Locating the EMI shield  210  on the plug  104  enables the alignment of the EMI shield  210  with the grounding clip when the plug  104  is installed in the connector housing  108 . 
         [0031]      FIG. 2B  illustrates the circuit board  212  with the multiple connector housings  108  from a front perspective.  FIG. 2B  represents a post-installation of the plug  104  as in  FIG. 2A  in one of the multiple connector housings  108 . 
         [0032]      FIGS. 3A-3C  illustrate various perspectives of an example plug  104  installed into a connector housing  108 .  FIGS. 3A-3C  illustrate the example plug  104  as coupled to the connector housing  108  in such a manner an electrical contact  102  located on the plug  104  provides a connection to a connector pin  110  within the connector housing  108 . 
         [0033]      FIG. 3A  is an illustration from a front perspective of the plug  104  as installed in the connector housing  108  while another connector housing  108  remains uncoupled to another plug. For example, the plug  104  is installed in the connector housing  108  on the left hand side; however, the plug  104  is coupled to the connector housing in such a manner that the connector housing  108  is not illustrated from the front perspective. The connector housing  108  in the right hand side of the  FIG. 3A  represents the connector housing  108  without the plug  104 . In this illustration, the connector housing  108  represents an open connector housing. 
         [0034]      FIG. 3B  is an illustration from a side perspective of a cross-sectional view of the plug  104  supporting the electrical contact  102  for alignment with the connector pin  110  in the connector housing  108 . The electrical contact  102  is aligned to the connector pin  110 , upon the installation of the plug  104  into the connector housing  108 . 
         [0035]      FIG. 3C  is an illustration from a top perspective of a cross-sectional view of the plug  104  installed in the connector housing  108  in such a manner that the electrical contact  102  connects to the connector pins  110  within the connector housing  108 . Additionally,  FIG. 3C  includes an identification chip  306  which enables a processor (not illustrated) to identify a type of plug  104  installed in the connector housing  108 . The identification chip  306  provides specific identifying information of the plug  104  to the processor. Such identifying, information may include, by way of example, universally unique identifier (UUID), a number of electrical contacts, material of the plug  104 , a number of rows within the plug  104 , shape of the plug  104 , whether the plug  104  supports the EMI shield, or other type of identifying information distinguishing the plug  104  among multiple plugs. 
         [0036]      FIG. 4  illustrates an example system of an interconnect module  418  within a blade server enclosure (not illustrated). The interconnect module consists of a faceplate  416 , where two connector housings  108  are disposed,  FIG. 4  also illustrates a plug  104  before installation and post-installation in a connector housing  108 . Prior to installation of the plug  104 , a heated airflow  426  enters an interconnect module  418  through an open connector housing  108 . Post installation of the plug  104 , prevents the heated airflow  426  from entering the interconnect module  418  by scaling the opening connector housing  108 . Additionally, post-installation of the plug  104  enables a cooler airflow  427  to be directed across a networking switch  422 . Upon installation of the plug  104  within the connector housing  108 , an electrical contact  102  connects with a connector pin  110  within the connector housing  108  creating a closed circuit for a processor  420  to detect a presence of the plug  104  through installation of the plug  104  and as such transmits a signal indication to power up and/or change operational states of the networking switch  422 . The networking switch  422  connects to a blade server through a switch port connector  424 . The switch port connectors  424  provide a connection between the networking switch  422  and the blade servers (not illustrated). 
         [0037]    When the plug  104  is installed in the connector housing  108  through an alignment of an electrical contact  102  and a connector pin  110 , the plug  104  installation prevents the heated airflow  426  through the connector housing  108 . In this instance, when the plug  104  is installed in the connector housing  108 , the installation seals against the heated airflow  426  through the connector housing  108 . Sealing the housings  108  allows cool air to he pulled through the interconnect module  418  via the airflow paths  427 . Blade server enclosures (not illustrated including the fans (not illustrated) to create the airflow paths  427 . 
         [0038]    The faceplate  416  supports openings to provide the housing connectors  108 . The faceplate  416  is considered a front panel to the interconnect module  418 . This front panel may provide protection to the components within the interconnect module  418  from environmental aspects. Additionally, the faceplate  416  supports the connector housing  108  allowing the installation of the plug  104  into the interconnect module  418 . The faceplate  416  is part of the interconnect module chassis for enclosing the hardware components in  FIG. 4 . 
         [0039]    The interconnect module  413  contains a circuit board  417  which in turns contains the networking switch  422 . The networking switch  422  provides packet switching to blade servers which are connected to the networking switch  422  through the switch port connectors  424 . Each switch port connector  424  couples to a server blade in a blade enclosure (not illustrated). The interconnect module  418  may include, by way of example, a fan (not illustrated) which operates to cool the networking switch  422 , the processor  420 , and other components within the interconnect module  418  when in operation by creating the cooler airflow paths  427 . 
         [0040]    The processor  420  detects the closed circuit between the electrical contact  102  and the connector pin  110 . Detecting the connection between the electrical contact  102  and the connector pin  110  indicates to the processor  420  the installation or presence of the plug  104  within the connector housing  108 . Implementations of the processor  420  include, by way of example, a processing unit, host processor, microprocessor, semiconductor, integrated circuit, or other type of electronic device capable of detecting the installation of the plug  104  in the connector housing  108 . 
         [0041]    The networking switch  422  is a component which provides routing of the multiple networking packets from, or to, the switch port connectors  424 . The networking switch  422  is a computer networking device which routes network packets from server blades (not illustrated) coupled via the switch port connectors  424 . The server blade(s) may be located on the other side (not illustrated) of the multiple switch port connectors  424 . In one implementation, when the processor  420  detects a presence or installation of the plug  104  in the connector housing  108 , it transmits a signal to the networking switch  422  to power up. Powering up includes increase an amount of power drawn by the switch  422 , thus enabling the networking switch  422  to receive and route packets accordingly. In another implementation, if the processor  420  detects an absence (e.g., non-installation) of the plug  104  from the connector housing  108 , the processor  420  transmits the signal to the networking switch  422  to remain powered down. In this implementation, the processor  420  transmits a signal to a component within the interconnect module  418 . This signal indicates to the networking switch  422  to change in operating state. For example, if the networking switch  422  is in a lower powered mode, the signal indicates the installation of the plug  104  and thus the networking switch  422  change, operating state to power up. This implementation is discussed in a later figure. In another example if the networking switch  422  has been powered down, then if the plug  104  is not installed, the networking switch  422  may remain powered down ensuring minimal heat is generated. 
         [0042]    The processor  420  detects the installation of the plug  104  within the connector housing  108  through detecting a closed circuit connection between the electrical contact  102  on the plug  104  and the connector pin  110  on the connector housing  108 . After detecting the installation of the plug  104 , the processor  420  transmits a communication signal to the networking switch  422  to be powered up and start routing network packets from multiple switch port connectors  424 . Implementations of the networking switch  422  include chipset, silicon chip, microchip, controller, or other type of networking switch component capable of routing the network packets from multiple switch port connectors  424 . 
         [0043]    The heated airflow  426 , represents a heated airflow through the connector housing  108  when the plug  104  is not installed or prior to installation of the plug  104 . The heated airflow  426  may enter the interconnect module  418  via vent opening  209 . Having an uninstalled plug  104  leaves the connector housing  108  open which means heated air may be drawn by the fan (not illustrated) from the interconnect module  418  to cool the components within the interconnect module  418 , such as the networking switch  422 . Leaving the connector housing  108  open without the installation of the plug  104 , provides an inefficient cooling system as the heated airflow  426  drawn through the connector housing MS may not be adequate to cool the networking switch  422  when this switch  422  is powered on. Installing the plug  104  in the connector housing  108 , provides the seal which prevents the heated airflow  426  from entering the interconnect module  418  through the open connector housing  108 . Preventing the heated airflow  426  upon the installation of the plug  104  in the connector housing  108 , enables the fan (not illustrated) to pull cooler air from a side of the interconnect module  418  via the cooler airflow paths  427 . Pulling in the cooler airflow  427  ensures a more efficient mechanism for cooling the switch  422  within the interconnect module  418 . 
         [0044]      FIG. 5  is flowchart of an example method to detect, upon a coupling of a plug with a connector housing, a connection between an electrical contact supported by the plug and connector pin supported by the connector housing. Based upon this connection, the method detects a presence of the plug. The presence of the plug, indicates an installation of the plug within the connector housing. In discussing  FIG. 5 , references may be made to the components in  FIGS. 1-4  to provide contextual examples. For example, the processor  420  as in  FIG. 4  executes operations  502 - 506  for detecting the presence of the plug in connection with the connector housing. In another example, a computing device executes operations  502 - 506 . In one implementation, the computing device may include the interconnect module  418  as in  FIG. 4  and as such, the interconnect module  418  may execute operations  502 - 506 . Further, although.  FIG. 5  is described as implemented by the processor, it may be executed on other suitable components. For example,  FIG. 5  may be implemented in the form of executable instructions on a machine-readable storage medium. 
         [0045]    At operation  502 , the processor detects whether the connection between the electrical contact and the contact pin has been established. Operation  502  occurs upon the coupling of the plug to the connector housing. Coupling the plug to the connector housing includes, by way of example, bringing together the plug and the computing system in such a manner the connection may be established. The connection includes joining together a circuit on the plug with the circuit on the connector housing when bringing the plug together with the connector housing. If the processor determines the connection between the electrical contact and the connector pin has not been established, the processor may proceed to operation  504  and does not detect a presence of the plug with the connector housing. If the processor determines the connection between the electrical contact and the connector pin is established, the processor proceeds to operation  506  to detect the presence of the plug with the connector housing. 
         [0046]    At operation  504 , if the connection between the plug and the connector pin is not established at operation  502 , the processor does not proceed to detect the presence of the plug. In one implementation operation  504  includes detecting the absence of the plug with the connector housing. 
         [0047]    At operation  506 , the processor detects the presence of the plug. The presence of the plug indicates the installation of the plug with the connector housing. In this implementation, the plug is coupled with the connector housing in such a manner that the electrical contact and the connector pin have formed a closed circuit indicating to the processor the presence of the plug. In another implementation of operation  506 , the presence of the plug with the connector housing means the plug has been joined together with the computing system supporting the connector housing in such a manner that it prevents a flow of air from coming through the connector. The presence of the plug may include, by way of example, sealing the connector from an environment outside of the computing system. 
         [0048]      FIG. 6  is a flowchart of an example method to detect a connection between an electrical contact supported by a plug and a connector pin supported by a connector housing. Based on whether this connection is detected, the method may proceed to align an electromagnetic interface (EMI) shield located on the plug with a grounding clip located in the connector housing. Aligning the EMI shield includes, by way of example, creating an electrical connection with the grounding clip in such a manner to prevent EMI leakage through an open connector housing. Preventing the EMI leakage minimizes the EMI fields which may interfere with other various hardware components. Additionally, the method further detects whether the plug is present in the connector housing. Based on this detected presence, the method may proceed to transmit a signal. The signal indicates to change operational states and/or change power states for a networking switch. If the plug is not detected, the networking switch may remain powered down. The connector housing is attached to a computing system and serves as a connector for interfacing with other various components. The computing system includes, by way of example, a server and/or interconnect module which houses a networking switch. Thus detecting the presence and of installation of the plug prior to changing the operational state of the networking switch ensures a more efficient mechanism for cooling the networking switch within the interconnect module. In discussing  FIG. 6 , references may be made to the components in  FIGS. 1-4  to provide contextual examples. For example, the processor  420  as in  FIG. 4  executes operations  602 - 614  for detecting the presence of the plug in connection with the connector housing. In another example, a computing device executes operations  602 - 614 . In one implementation, the computing device may include the interconnect module  418  as in  FIG. 4  and as such, the interconnect module  418  may execute operations  602 - 614 . Further, although  FIG. 6  is described as implemented by the processor, it may be executed on other suitable components. For example,  FIG. 6  may be implemented in the form of executable instructions on a machine-readable storage medium. 
         [0049]    At operation  602 , the processor detects whether the connection between the electrical contact and the connector pin has been established. If the processor does not detect the establishment of the connection between the electrical contact and the connector pin, the method may proceed to operation  604 . If the processor detects the connection between the electrical contact and the connector pin has been established, the processor may proceed to operation  606  to align the EMI shield on the plug with the grounding clip in the connector housing. Operation  602  may be similar in functionality to operation  502  as in  FIG. 5 . 
         [0050]    At operation  604 , the EMI shield on the plug is not connected with the grounding clip in the connector housing. Determining the connection has not been established at operation  602 , the EMI shield is not aligned with the EMI shield. Determining the connection has not been established indicates the connector housing may be in the situation of an open connector. Having an open connector potentially means heated air being drawing through the open connector thus not efficiently cooling the networking switch in the interconnect: module of the computing system. Further, determining the connection has not been established may indicate the plug has not been brought together with the connector of the computing system in such a manner that prevents the flow of air through the connector. The absence of the connection indicates the plug is absent and/or partially coupled with the connector housing. 
         [0051]    At operation  606 , upon the establishment of the connection at operation  602 , the EMI shield is aligned with the grounding clip in the connector housing. The EMI shield is connected to the plug in such a manner that when the connection is established at operation  602 , the EMI shield may also be connected with the grounding dip. The EMI shield, by way of example, consists of a strip of conductive material which connects or interfaces with the grounding clip within the connector housing. The grounding clip may also consist of conductive material which carries the electromagnetic field within the connector housing to ground. As such, placement of the EMI shield in connection with the grounding clip prevents the leakage of the electromagnetic interference which may interfere with other hardware components surrounding the connector housing. 
         [0052]    At operation  608 , the electromagnetic field is grounded for preventing interface with other components. Operation  608  may occur simultaneously as the alignment of the EMI shield with the grounding clip at operation  606 . 
         [0053]    At operation  610 , the processor detects whether the plug is present in the connector housing. In one implementation, the connection between the electrical contact and the connector pin creates a closed circuit signaling to the processor the presence of the plug in the connector housing. This implementation may be discussed in the next figure. Operation  610  may be similar in functionality to operation  506  as in  FIG. 5 . 
         [0054]    At operation  612 , upon detecting the absence of the plug from the connector housing, the processor transmits the signal for the networking switch to remain powered down. Transmitting the signal for the networking switch to remain powered down ensures the networking switch may not be generating excess heat. This ensures a minimal amount of heat is generated for the cooling system in the situation of an open connector that may draw in a heated airflow. Operation  612  may include, by way of example, transmitting the signal to the networking switch to remain in a standby state, power state, or other type of lower powered state. 
         [0055]    At operation  614 , upon detecting the presence of the plug with the connector housing, the processor transmits the signal to the networking switch or another component which manages the networking switch. The signal indicates for the networking switch to change operational state. For example, if the networking switch is in a low-powered state, the signal may indicate to power up the networking switch so the switch may route packets accordingly. As such in this example, the signal may include increasing the power drawn by the networking switch. Transmitting the signal for powering up the switch to power up may include instructing the networking switch to begin receiving packets and routing the packets accordingly. 
         [0056]      FIG. 7  is a flowchart of an example method, upon a coupling of a plug with a connector housing, to detect a connection between an electrical contact supported by the plug and a connector pin supported by the connector housing. If the method detects this connection, the method may proceed to detect a presence of the plug with the connector housing. Otherwise, if the method does not detect the connection, the method does not detect the presence of the plug with the connector housing. The presence of the plug with the connector includes closing a circuit between the electrical contact and the connector pin. The closed circuit allows a processor to detect the closed circuit which indicates the presence of the plug. Upon dosing the circuit between the electrical contact and the connector pin, the processor transmits a signal indicating to a networking switch to power up or change operational state. Waiting to power up and/or change operation state of the networking switch until detecting the installation of the plug with the connector housing, provides a more efficient mechanism for cooling the networking switch. For example, when the networking switch is powered up, it may generate more heat, thus the presence of the plug prevents the heated airflow back through the connector housing and enables a more efficient cooler airflow. In discussing  FIG. 7 , references may be made to the components in  FIGS. 1-4  to provide contextual examples. For example, the processor  420  as in  FIG. 4  executes operations  702 - 712  for detecting the presence of the plug in connection with the connector housing. In another example, a computing device executes operations  702 - 712 . In one implementation, the computing device may include the interconnect module  418  as in  FIG. 4  and as such, the interconnect module  418  may execute operations  702 - 712 . Further, although  FIG. 7  is described as implemented by the processor, it may be executed on other suitable components. For example,  FIG. 7  may be implemented in the form of executable instructions on a machine-readable storage medium. 
         [0057]    At operation  702 , the plug is coupled with the connector housing. Coupling the plug with the connector housing includes bringing together the two components (i.e., the plug and the connector housing). Bringing together these components, allows the plug and the connector housing to interface with each other. The plug and connector housing interface with each other by connecting the electrical contact on the plug with the connector pin on the connector housing. Operation  702  may include aligning the electrical contact with the connector pin for the processor to detect the connection at operation  704 . Upon coupling the plug with the connector housing, the processor detects whether the connection was produced between the electrical contact and the connector pin as at operation  704 . 
         [0058]    At operation  704 , the processor may detect whether the connection between the electrical contact supported by the plug and the connector pin supported by the connector housing is established. If the processor detects the absence of the connection between the electrical contact and the connector pin, the processor may proceed to operation  706  and does not detect the presence of the plug with the connector housing. The reason for this is the absence of connection indicates the plug is absent from the connector housing. Thus, the processor will be unable to detect the presence of the plug with the connector housing. If the processor is successful in detecting the connection between the electrical contact and the connector pin, the processor proceeds to operation  708  to detect the presence of the plug with the connector housing. 
         [0059]    At operation  706 , the processor does not detect the presence of the plug with the connector housing. As explained in connection with operation  704 , the absence of the connection between the electrical contact and the switch pin indicates the absence of the plug with the connector housing. The absence of the plug may include, by way of example, the plug and the connector housing were not joined together in such a manner to allow the connection at operation  704 . For example, the plug may be partially coupled with the connector housing, which may not enable the connection between the electrical contact and the connector housing. 
         [0060]    At operation  708 , the processor detects the presence of the plug with the connector housing. In one implementation, the processor detects the presence of the plug through a closed circuit between the electrical contact and the connector pin supported by the connector housing as at operation  710 . Operation  708  may be similar in functionality to operations  506  and  610  as in  FIGS. 5-6 . 
         [0061]    At operation  710 , the processor receives a signal indicating the closed circuit between the electrical contact and the connector pin. Enabling the processor to receive the signal of the dosed circuit indicates the presence of the plug with the connector housing. In one implementation, operation  710  occurs simultaneously with operation  708 . For example, the processor detects the presence of the plug through the signal of the closed circuit. In another implementation, operation  710  occurs prior to detecting the presence of the plug. The connector pin serves as a type of sensing pin which signals to the processor the closed circuit between the connector pin and the electrical contact. The connection of the closed circuit signifies to the processor the plug is present. 
         [0062]    At operation  712 , upon detecting the presence of the plug with the connector housing at operation  708 , the processor transmits the signal to the networking switch or another component which manages the networking switch. The signal indicates for the networking switch to power up and/or change operational state. In one implementation, the networking switch may be operating with minimal power such as in a standby state. Thus to increase functioning, the networking switch may pull additional power to enable the additional functioning. In another implementation, the networking switch may be in an off-state drawing no power, thus upon powering up, the networking switch may be pulling the increase of power to increase functionality Operation  712  may be similar in functionality to operation  614  as in  FIG. 6 .
