In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Description of drawings

Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.

In the accompanying drawing,

Fig. 1 is the module diagram of the utility model gigabit switch internal structure;

Fig. 2 is the schematic diagram of the utility model gigabit switch main panel.

Embodiment

For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

As shown in Figure 1, the utility model provides a kind of gigabit switch, it comprises: casing, and be installed on motherboard circuit (not shown) in the casing, this casing comprises a main panel 10, and around common several side panels of forming casing of this main panel 10 and its, an end is provided with LED Unit 12 on this main panel 10, the other end is provided with the fiber port 14 that three yi word patterns are arranged, and this motherboard circuit comprises processor 20, this processor 20 be located at around it for centering ring and with the power module 21 of its electric connection, lamp shows 22, and PHY group 23, and be located at PHY group's 23 1 ends and with the optical fiber port module 24 of its electric connection.Described processor 20 is used to realize the data operation function, power module 21 provides electric device for this gigabit switch, lamp shows the operating state of 22 corresponding each fiber ports 14, PHY group 23 is used to finish the conversion between fiber-optic signal and the processor signal, three fiber ports, 14 corresponding electric connections on this optical fiber port module 24 and the main panel 10 are used for plugging the usefulness of interface.LED Unit 12 on lamp demonstration 26 and the main panel 10 electrically connects.
