Switch Panel
ET4222Pp-S-DR Side panel: P1 and P2 are the number of connecting terminals, P+1 and P-1 are
respectively to the positive and negative poles to be connected; Earthing screw, used for earthing
equipment.
ET4222Pp-S-DR 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.
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-
1, 6-2, 4-7, 5-8, 7-4, 8-5.1000Base-T (X) pins are defined as follows:

Installation caution
⚫Installation precautions
In order to avoid damage to equipment and personal injury caused by improper use, please
follow the following precautions:
a) In order to avoid damage caused by falling of the equipment, please put the equipment in
a stable environment.
b) 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.
c) In order to reduce the risk of electric shock, ensure that the equipment is well grounded in
the working environment.
d) No matter when, please do not arbitrarily remove the equipment shell.
When placing the switch, please avoid the area with dust and strong electromagnetic

Quick Installation Guide
ET4222Pp-S-DR / version 2.3
⚫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.
⚫Grounding
Fix the grounding wire to the grounding screw above the switch, and ensure
good reliable connection of the grounding system.
⚫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
To ensure trouble free transportation and storage, all OT Systems products must be thoroughly
inspected, tested and properly packed before delivery. Check the product upon receipt for any
visible damage which may have been caused during shipment.
