Description

Switch

Technical field

The utility model relates to a kind of switch.

Background technology

At present, the unit of industry gigabit ethernet switch is supported 48 electricity mouths at most, and this is because the size of the overall dimension of standard PC case and connector (as RJ45) has limited the port number of rack switch unit on physical space.Switch more than 48 mouthfuls all adopts frame structure to come Extended Capabilities Port by backboard, make complex structure, cost an arm and a leg, thereby be not suitable for building the application of middle and small scale Network of Workstation.

Fig. 1 is the schematic diagram that the existing switch configuring ports is shown.

The ES64 switch is the rack switch, must be installed in the rack of standard, and because the restriction of 19 inches width of rack, a row can only place 48 mouthfuls (adopting the 2X4RJ45 mode), thereby has limited the environment for use of switch.

Therefore, needs are a kind of can Extended Capabilities Port number and switch simple in structure, that cost is low

Summary of the invention

Consider the problems referred to above and make the utility model.

Main purpose of the present utility model is to provide a kind of switch, comprises a plurality of ports, also comprises: a plurality of expansion subcards are connected to the port that position in a plurality of ports is in the first half; And a plurality of connectors, a plurality of number of connectors are identical with the quantity of a plurality of expansion subcards, connect to concern one to one, are used for a plurality of expansion subcards are connected to the mainboard of switch.

Wherein, the width of switch is 19 inches, highly is 2U.

Preferably, the height of a plurality of connectors is greater than the height of the port of switch, and a plurality of connector comprises many to differential lines.Four times of the quantity that many quantity to differential lines are the port that the position is in the first half in a plurality of ports.

In addition, realize the gigabit Ethernet Routing Protocol by the process chip in the mainboard, many to control to differential lines.

Preferably, the model of a plurality of ports is RJ45, and the set-up mode that is adopted is 2X4RJ45.

Preferably, the quantity of a plurality of ports can reach 96 at most.

By the technical solution of the utility model, can be easily the port of switch be expanded to 96 mouthfuls, and simple in structure, cost is low.

Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:

Fig. 1 is the schematic diagram that the existing switch configuring ports is shown;

Fig. 2 is the schematic diagram that illustrates according to the integral layout of the switch of the utility model embodiment; And

Fig. 3 is the schematic diagram that illustrates according to the port layout of the switch of the utility model embodiment.

Embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 2 is the schematic diagram that illustrates according to the integral layout of the switch of the utility model embodiment.

With reference to Fig. 2, front panel place at switch is provided with a plurality of ports, and two expansions subcards and two connectors are set in cabinet, wherein, the expansion subcard is connected to port that position in a plurality of ports is in the first half (promptly, the port of the row of going up shown in Fig. 2), connector is connected to concern one to one with the expansion subcard, and will expand the mainboard that subcard is connected to switch.

The represented part of chain-dotted line is the expansion subcard among Fig. 2, and connector is arranged on the pcb board, and connector is connected to port (that is, the port of the row of going up shown in Fig. 2) after the expansion by the expansion daughter board then, thereby realizes being connected of the port expanded and PCB.

In this embodiment, be provided with two expansions subcards and two connectors, but should be appreciated that expansion subcard and number of connectors are not limited to two, but can be one, three, four or the like.

The width of this switch is 19 inches, highly is 2U.Because the size restrictions of standard cabinet, width is identical with the width of existing switch, but highly becomes 2U, comes Extended Capabilities Port with this.

Note, to connector is conditional: its height should be higher than the height of port (as RJ45), otherwise can't realize and being connected of upper port, and a plurality of connectors need comprise many to differential lines, and many quantity to differential lines are four times of upper port (port that expansion just increases) quantity.That is,, then need 48 * 4=192 to differential lines if increased by 48 mouths.

In addition, realize the gigabit Ethernet Routing Protocol by the process chip in the mainboard, many to control to differential lines, because original mainboard can only be controlled 48 ports, therefore need to increase the internal logic resource of mainboard process chip, to control the differential lines that increase more.This process chip is not the problem that the utility model will be paid close attention to, and therefore omits the description to it.

In embodiment of the present utility model, the model of port is RJ45, and the set-up mode that is adopted is 2X4RJ45.But should be appreciated that the model and the set-up mode of port are not limited to this, but can adopt other any feasible model and modes.

Fig. 3 is the schematic diagram that illustrates according to the port layout of the switch of the utility model embodiment.For convenience of description, the port shown in Fig. 3 also adopts the set-up mode of 2X4RJ45.By embodiment of the present utility model, consider the upgrading of exchange from now on, the quantity of port can reach 96 at most.

As mentioned above, by the technical solution of the utility model, as long as by a plurality of connectors and a plurality of expansion daughter boards corresponding with it, just 48 mouths of switch can be expanded to 96 mouths, compare with the existing mode of backboard mode Extended Capabilities Port that adopts, structure is simpler, and cost is lower.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
