Abstract

The utility model discloses a PoE (Power Over Ethernet) switch, comprising a built-in switching module, a PSE module, a power module and a clock module, wherein the PSE module is connected with the power module and the clock module, respectively; and the PSE module, the power module and the clock module are connected with the switching module, respectively. The PoE switch further comprises an external AC (Alternating Current) power converter connected with the power module. The PoE switch provided by the utility model has the characteristics of small volume, easy installation, reduction of production cost and the like.

Description

A kind of PoE switch

Technical field

The utility model relates to network communication field, is specifically related to a kind of network switch with the PoE function of supplying power.

Background technology

PoE (Power Over Ethernet, Power over Ethernet) be also referred to as electric power system (PoL based on local area network (LAN), Power over LAN) or active Ethernet (Active Ethernet), sometimes also be called Power over Ethernet for short, this is the newest standards standard that transmits data and electrical power when utilizing existing standard ethernet transmission cable, and has kept the compatibility with existing Ethernet system and user.The IEEE802.3af standard is based on the new standard of Power over Ethernet system POE, and it has increased the relevant criterion of by netting twine, directly powering on the basis of IEEE802.3, is the expansion of existing ethernet standard, is also first international standard about power distribution.

As shown in Figure 1, traditional PoE switch comprises Switching Module, CPU module, PSE module, power module, clock module, AC power supplies transducer, power interface, network interface etc.

Yet above-mentioned PoE switch technology is complicated, and CPU is with high costs, and built-in AC power supplies transducer has increased small product size, causes this series products oversize (being generally 19 inches).Be unfavorable for on-the-spot the installation.

Along with popularizing of IP power supply, wireless aps, IP camera, NAS etc., market increases rapidly the demand of PoE switch, and is also more and more higher to the demand of product cost simultaneously.

The utility model content

, in order to address the above problem, be necessary to provide the PoE switch of a kind of low cost, small size.

The technical scheme that the utility model technical solution problem provides is:

A kind of PoE switch, it comprises built-in Switching Module, PSE module, power module and clock module, the PSE module is connected with clock module with power module respectively, PSE module, power module, clock module are connected with Switching Module respectively, wherein, described PoE switch further comprises the external AC power supplies transducer that is connected with power module.

Wherein, described PoE switch further comprises the network interface that is connected with Switching Module.

Wherein, described PoE switch further comprises for the power interface that connects power module and AC power supplies transducer.

Compared with prior art, POE switch of the present utility model built-in AC power supplies transducer has originally changed external AC power supplies transducer into, has greatly reduced the complexity of product, has reduced the cost of product, dwindled the size of product, be convenient in the installation without in the networking application.

Description of drawings

Fig. 1 is the system block diagram of the PoE switch of prior art.

Fig. 2 is the system block diagram of PoE switch of the present utility model.

Embodiment

As shown in Figure 2, PoE switch of the present utility model it comprise Switching Module, PSE module, power module, clock module, power interface, network interface and external AC power supplies transducer.The PSE module is connected with clock module with power module respectively.PSE module, power module, clock module are connected with Switching Module respectively.Switching Module further is connected to network interface.The PSE module is used for the PoE power supply management, the work such as power division, and Switching Module is used for the exchange to data and manages.POE switch of the present utility model built-in AC power supplies transducer has originally changed external AC power supplies transducer into, has greatly reduced the complexity of product, has reduced the cost of product, has dwindled the size of product.

The AC220V civil power is converted to direct current 48V power supply by external AC power supplies transducer, by power interface, inputs, and by power module, is converted to each module required voltage.Simultaneously by the PSE module, the power supply of direct current 48V is added on Switching Module, export the ethernet signal that also has direct current 48V by network interface, realize the PoE Remote feeding.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
