Interface Definition
10/100/1000Base-TX ethernet interface:
This series of switches provides MDI/MDI-X self-identification with cable support on all
10/100/1000Base-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-

l 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.
l Grounding
Fix the grounding wire to the grounding screw above the switch, and ensure
good reliable connection of the grounding system.
l 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 48VDC to 57VDC.
General
