5. Interface Definition

5.1 10/100/1000Base-TX Ethernet interface:

This switch provides MDI/MDI-X self-identification with cable support

on all 10/100/1000Base-TX ports. In use, the Ethernet port of the

switch can be connected with other Ethernet terminal devices through

network cables (direct or cross). Please use Class 5 shielded twisted

pair. The Ethernet port pin definition is shown in the following figure:

RJ45 port supports automatic MDI/MDI-X operation, you can use a

straight line to connect to the PC or server, connect to other switches

or hubs. In the through line (MDI), pins 1, 2, 3, 4, 5, 6, 7, 8 correspond

to the connection;

For the MDI-X port of a switch or hub, cross lines are used: 1-3, 2-6,

3-1, 6-2, 4-7, 5-8, 7-4, 8-5.10Base-T/100Base-T (X) pins are defined as

follows:

5.2 1000base-FX Ehernet interface

This device provides 1000Base single-mode dual-

fiber SC module, and multi-mode like LC, ST as optional.

5.2.1 Patch cord classification

According to the transmission mode of light in the fiber, it can be

divided into multi-mode fiber and single-mode fiber. Multimode fiber

has a thick glass core (50 or 62.5μm), which can transmit light in

various modes. However, the high inter-mode dispersion limits the

frequency at which digital signals can be transmitted, so multimode

fibers can be transmitted over relatively close distances (typically only

a few kilometers).

The single-mode fiber has a very thin glass core (core diameter, usually

9 or 10μm) and can transmit only one mode of light. Therefore, it’s

inter – module dispersion is very small, and it is suitable for remote

communication. Under normal circumstances, the skin is orange for

multi-mode, yellow for single mode.

5.2.2 SFP module (Optional, not included)

LC connector, Gigabit, 20km Single mode, dual fiber (DN-81011)

7. Installation caution

7.1 Installation precautions

In order to avoid damage to equipment and personal injury caused

by improper use, please follow the following precautions:

In order to avoid damage caused by falling of the equipment,

please put the equipment in a stable environment.

When supplying power to the equipment, pay attention to confirm

the range of power supply voltage, as well as the positive and

negative poles of the power supply, so as not to damage the

equipment by wrong operation.

In order to reduce the risk of electric shock, ensure that the

equipment is well grounded in the working environment.

No matter when, please do not arbitrarily remove

the equipment shell.

When placing the switch, please avoid the area with dust and

strong electromagnetic interference

7.2 Din rail installation:

The first step is to check the grounding and

stability of the guide rail: the guide rail slot of the

switch is clamped into the guide rail; The second

step: from the center to both sides of the guide

rail positioning screws in order. Step 3: Use

screws to fix the mounting rail card slot on the

fixed guide groove at both ends of the guide rail

to ensure that the guide rail and the switch are

fixed on the guide rail vertically and stably.

7.3 grounding

Fix the grounding wire to the grounding screw

above the switch, and ensure good reliable

connection of the grounding system.

7.4 Power Connection

Insert the power cord into the specified position of the 6-core terminal,

and insert the terminal into the standard power supply inlet (P+1 and

P-1 input corresponding to the first power supply P1, and P+2 and P-2

input corresponding to the second power supply P2). The available

voltage standard of the power supply is supported from 12VDC to

52VDC
