Description

Eight power port POE network interface card of gigabit

Technical field

The utility model relates to eight power port POE network interface cards of a kind of network transmission card more particularly to a kind of gigabit.

Background technique

The number of ports of general network interface card is single port, twoport or four mouthfuls currently on the market, and number of ports results in the need for being inserted into multiple less Network interface card is met the requirements.Multiple network interface cards just need multiple PCIe interfaces in corresponding server, and the PCIe interface number of server Again than relatively limited, certain server mainboard into only only one or two PCIe interfaces, when needing multiple interfaces due to PCIe interface not enough needs replacing mainboard, very troublesome, and Expenses Cost.

Therefore, the prior art is defective, needs to improve.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of eight power port POE network interface card of gigabit.

The technical solution of the utility model is as follows: providing a kind of eight power port POE network interface card of gigabit, comprising: PCIe bridging chip, What the first network card chip being electrically connected with the PCIe bridging chip downlink and the PCIe bridging chip downlink were electrically connected Second network card chip, four the first power port connectors being electrically connected with the first network card chip electrically connect with the second network card chip Four the second power port connectors connect, the POE electricity being electrically connected with the first power port connector and the second power port connector Source control chip, the first boost module being connect with POE power management chip, connect with POE power management chip second liter Die block, the ATX power interface being electrically connected with the first boost module and the second boost module.

Further, the model PI7C9X2G312 of the PCIe bridging chip.

Further, the model INTEL I350 of first network card chip and the second network card chip.

Further, the first power port connector and the second power port connector are gigabit RJ45 connector, the RJ45 Connector is equipped with POE filter.

Further, the model IC+IP808 of the power management chip.

Further, first boost module and the second boost module use chip LM5022.

Using the above scheme, the utility model has the following beneficial effects:

(1) the case where the utility model is for more mouthfuls of network interface cards are lacked on existing market, a kind of eight power port network interface card of gigabit is designed To fill up market demand vacancy, it is possible to reduce replacement server master board is removed in the dependence to PCIe interface on server master board from Trouble, and the utility model structure is simple, and compared to the network interface card for using two four ports, cost is cheaper；

(2) the utility model has the function of POE power supply, this network interface card can be connected by cable and is supplied to other load equipments Electricity thus no longer needs to that power supply is provided separately to load equipment.

Detailed description of the invention

Fig. 1 is the system structure diagram of the utility model.

Fig. 2 is the circuit diagram of the utility model the first boost module and the second boost module.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to Fig. 1, the utility model provides a kind of eight power port POE network interface card of gigabit, comprising: PCIe bridging chip and institute Second for stating the first network card chip of PCIe bridging chip downlink electric connection, being electrically connected with the PCIe bridging chip downlink What network card chip, four the first power port connectors being electrically connected with the first network card chip and the second network card chip were electrically connected Four the second power port connectors, the POE power supply pipe being electrically connected with the first power port connector and the second power port connector Reason chip, the first boost module being connect with POE power management chip, the second boosting mould being connect with POE power management chip Block, the ATX power interface being electrically connected with the first boost module and the second boost module.

The PCIe bridging chip carries out data by the golden finger and server master board of the PCIe X4 width of standard and leads to News, PCIe bridging chip downstream end Qiao contact the PCIe X4 interface of two standards, and the base for the 100MHZ for simultaneously providing mainboard Clock signal is extended to two, and two expanded PCIe signal and two reference clock signals connect the first network card chip respectively With the second network card chip, the first network card chip and the second network card chip respectively connect one group of 4 power port connector, to be extended to eight Power port.

Referring to Fig. 2, first boost module is identical as the second boost module structure, use chip LM5022 and Metal-oxide-semiconductor CSD19537Q3 realizes boosting, and it is required to be that the first boost module and the second boost module provide by ATX power interface Voltage.Realize that the POE of 8 power ports powers by the first boost module and the second boost module, while by POE power management chip Carry out the management of power supply, the model IC+IP808 of the power management chip.

The model PI7C9X2G312 of the PCIe bridging chip.

The model INTEL I350 of first network card chip and the second network card chip.

The first power port connector and the second power port connector are gigabit RJ45 connector, which is equipped with POE filter.
