  Tenth, the PoE function control unit includes a PoE board controller that acquires a PoE setting value from the PoE configuration controller and changes the setting.

  Eleventh, the PoE function control unit includes a PoE status monitor that acquires a current status of the PoE board from the PoE board controller.

  Twelfth, the PoE function control unit includes an LED controller that controls the LED by acquiring the current state and setting state of the PoE board from the PoE state monitor and the PoE configuration controller, respectively.

  According to the present invention having the features as described above, it is possible to change the setting very easily by providing a mechanical switch that can be manually set. Compared with a conventional switching hub that can be controlled by software. A cheaper PoE feeding side switching hub is provided.

  FIG. 1 is a schematic external view showing an embodiment of a PoE power supply side switching hub of the present invention.

  As shown in FIG. 1, the PoE power supply side switching hub of the present embodiment has a mechanical switch, and various settings can be manually performed by the mechanical switch.

  Functions that can be set include PoE power supply priority and PoE supply power amount class.

  The PoE power supply priority can be set to four levels of DISABLE / LOW / HIGH / CRITICAL for each port.

  The PoE power supply class can set the PoE power supply class for each port in four levels of Class 0/1/2/3.

  The mechanical switches that enable these settings to be changed manually are: Mode Select Switch (LED Mode Select Switch) 1, Port Select / Set Push Switch (Configuration Push Switch) 2, Set Value Select Dip Switch (Configuration Select Dip Switch) ) 3.

  The mode selection push switch 1 selects the display mode of the port status / setting value confirmation LED (FE / PoE Port Status LED) 4 that displays the status of the FE / PoE port for each port, that is, the port status / setting value. This is a push switch for selecting information to be displayed on the confirmation LED 4. In the present embodiment, the following four types of modes can be selected.

Mode 1. Link status display (initial value)
Mode 2. 2. Power supply status display mode Priority setting value display mode 4. Supply power amount class setting display When the mode selection push switch 1 is pressed while the mode 1 is displayed on the port state / setting value confirmation LED 4, the mode 2 is displayed. Each time the button is pressed, mode 2 to mode 3, mode 3 to mode 4 are displayed, and mode 1 is displayed from the state in which mode 4 is displayed. The currently selected mode can be confirmed by a mode display LED (LED Mode LED) 5 for sequentially displaying modes 1 to 4 as shown in FIG. 2, for example.

  The port selection / setting push switch 2 is a push switch for selecting and setting a PoE port # whose setting is to be changed. The port selection / setting push switch 2 operates only when the mode 3 or the mode 4 is selected.

  A port whose setting is to be changed can be selected by performing a short push, which is a press within one second, to the port selection / setting push switch 2. As with the mode selection push switch 1, the ports can be selected in order each time the number 1 to number N are pressed. The port status / setting value confirmation LED 4 of the selected port displays the setting value in a blinking manner, for example, as shown in FIG. In the initial state, port 1 is in the selected state.

  On the other hand, the setting value selected by the setting value selection DIP switch 3 described below can be reflected by performing a long push that is a press for one second or longer. For example, as shown in FIG. 4, when the setting value selected by the setting value selection DIP switch 3 is different from the current setting value, the blinking speed increases (middle diagram in FIG. 4). When the setting is reflected, the blinking speed is restored (the bottom diagram in FIG. 4). If the short push is performed without executing the long push, the setting of the next port is changed without reflecting the selected setting value.

  The set value selection DIP switch 3 is a DIP switch for selecting setting change contents. This set value selection DIP switch 3 also operates only when the mode 3 or mode 4 is selected. In FIGS. 5A to 5D, the priority order LOW or the power supply class 1 is selected, the priority order HIGH or the power supply class 2 is selected, and the priority order CRITICAL or the power supply class 3 is selected in order. It indicates that the priority is DISABLE or the power supply class 0 is being selected.

  Hereinafter, an example of a procedure for setting the PoE power supply priority will be described with reference to FIGS. In this example, the procedure for changing the PoE priority of port 5 from LOW to CRITICAL is shown. The procedure for setting the PoE power supply energy class is changed in the same procedure, and thus the description thereof is omitted.

  First, the mode selection push switch 1 is short-pushed twice to switch the mode 1 in the initial state set for the port 1 (see FIG. 6A) to the mode 3 (FIG. 6B). reference). At this time, as shown in FIG. 6B, the port state / setting value confirmation LED 4 corresponding to port 1 blinks slowly.

  Next, the port selection / setting push switch 2 is short-pushed four times to select the port 5 (see FIG. 6C). At this time, as shown in FIG. 6C, the port state / setting value confirmation LED 4 corresponding to the port 5 blinks slowly.

  Subsequently, the set value selection DIP switch 3 is set to the set value CRITICAL (see FIGS. 6D and 5C). When the selected value is a selection value different from the current state, as shown in FIG. 6D, the slow blinking of the port state / setting value confirmation LED 4 corresponding to the port 5 is changed to the fast blinking.

  Then, the port selection / setting push switch 2 is pushed long once (see FIG. 6E). When the setting is reflected, as shown in FIG. 6E, the port state / setting value confirmation LED 4 rapidly blinks slowly to slowly blink.

  The embodiment of FIG. 1 in which the above-described mechanical switch enables manual setting of the PoE power supply priority order and the PoE supply power amount class as described above further includes a reset switch (Reset Switch) 6, a Power / Fault LED 7, and a PoE meter LED. (PoE Meter LED) 8, PoE FE Port (PoE FE Port) 9, GbE T Status LED (GbE T Status LED) 10, Uplink GbE Combo Port (Up-Link GbE Combo Port) 11, GbE SFP Status LED (GbE SFP Status LED) 12 is provided.

  The reset switch 6 is a push switch that executes a system reset.

  The Power / Fault LED 7 is an LED that displays a power supply state and a system state.

  The PoE meter LED 8 is an LED that displays the PoE power supply state of the entire system.

  The PoE FE port 9 is a 10/100 RJ45 port.

  The GbET state LED 10 is an LED that displays a link state when the link is up at 10/100/1000.

  The uplink GbE combo port 11 is a GbE port in which either 10/100/1000 RJ45 or SFP is enabled.

  The GbE SFP status LED 12 is an LED that displays a link status when the SFP is linked up.

  As for the internal configuration of the switching hub of the present embodiment including these various switches and LEDs, for example, as illustrated in FIG. 7, an FPGA (Field Programmable Gate Array) or Micro-Controller is provided, and a PoE function control unit ( PoE Function Management Block) is built in.

  The PoE function control unit executes functions performed by the CPU in a conventional switching hub with an FPGA or a one-chip microcomputer, and includes a mechanical switch monitor, a PoE configuration controller, A PoE board controller, a PoE status monitor, and an LED controller are provided.

  The mechanical switch monitor detects a change in the state of the mechanical switch and notifies the PoE configuration controller.

  The PoE configuration controller acquires the state of the mechanical switch from the mechanical switch monitor and updates the PoE setting value. Also, after the setting is changed, the setting status is notified to the PoE board controller.

  The PoE board controller acquires the PoE setting value from the PoE configuration controller and changes the setting. Also, the current state is acquired from the PoE board and notified to the PoE state monitor.

  The PoE status monitor acquires the current status of the PoE board from the PoE board controller and notifies the LED controller.

  The LED controller obtains the current status and setting status of the PoE board from the PoE status monitor and PoE configuration controller, and turns on, blinks, and turns off the LED.

  The PoE power supply side switching hub of the present embodiment as described above can change the PoE setting even by a user who cannot operate the PC by realizing a manual setting change function.

  In addition, since the CPU, FlashROM, SDROM, and PLD (Programmable Logic Device) used in the conventional switching hub become an FPGA or a one-chip microcomputer, it leads to a reduction in component costs and a reduction in power consumption.

  Furthermore, since there is no OS intervention, real-time performance from confirmation of the current state to display can be improved.
