connecting terminals, P+1 and P-1 are respectively to the

positive and negative poles to be connected; Earthing screw,

used for earthing equipment.

DN-652120 Front panel: The yellow light on the port is the

LINK light, which is on when the connection is established,

and the data transmission is flashing. The green light is PoE

light, which is only on when the switch port is supplying

power to the PD devices. Power indicator light is on when

connecting with Power.

6. Interface Definition

10/100/1000Base-TX ethernet interface:

This series of switches provides MDI/MDI-X self-identification

with cable support on all 10/100/1000 Base-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, 8-5.1000Base-T (X) pins are defined as follows:

Pin No.

8. Installation caution

8.1 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

8.2 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.

8.3 grounding

Fix the grounding wire to the grounding screw above the

switch and ensure good reliable connection of the grounding

system.

8.4 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
