Chapter 2 Installation
2.1 Cautions
Similar to other electronic products, the semiconductor chip easily gets damaged if you power on and
off abruptly and frequently. To restart up the switch of DS-3T3512P, you have to open the power
on-off three or five seconds after the power is cut off.
Avoid severe collision or falling down from the height to protect the parts in the switch.
Use correct outside ports to connect the switch of DS-3T3512P. Do not insert the Ethernet plug into
the console port (RJ45 8-line socket). Similarly, do not insert the console cable into the console port
(RJ45 8-line socket).
Note:
1) When you plug or dial out the power line, keep the power line horizontal with the power socket.
2) When the lifetime of our products ends, handle them according to national laws and regulations,
or send these products to our company for collective processing.
3) When using the product, please use the chassis that meets the fire protection requirements
2.2 Safety Advice
2.2.1 Safety Principles
Keep dustless and clean during or after the installation.
Put the cover at the safe place.
Put tools at the right place where they are not easily falling down.
Put on relatively tight clothes, fasten the tie or scarf well and roll up
the sleeve, avoiding stumbling the chassis.
Put on the protective glasses if the environment may cause damage
to your eyes.
Avoid incorrect operations that may cause damage to human or
devices.
2.2.2 Safety Notices
The safety notices mentioned here means that improper operation may lead to body damage.
Read the installation guide carefully before you operate the system.
Only professionals are allowed to install or replace the switch.

Pull out the AC power socket and close the direct-current power
before operating on the chassis or working beside the power source.
The final configuration of products must comply with relative
national laws and regulations.
2.2.3 Safety Principles for Live Working
When you work under electricity, following the following principles:
Put off ornaments, such as ring, necklace and watch, before you
operate under live working. When metal articles connect the power
to the ground, short circuit happens and components may be
damaged.
Pull out the AC power socket and close the direct-current power
before operating on the chassis or working beside the power source.
When the power is on, do not touch the power.
Correctly connect the device and the power socket.
Only professionals are allowed to operate and maintain the device.
Read the installation guide carefully before the system is powered
on.
Note:
1) Check potential dangers, such as the humid floor, ungrounded
extensible power line and tatty power line.
2) Install the emergent on-off at the working room for turning off the
power when trouble happens.
3) Turn off the power on-off of the switch and plug off the power line
before installing or uninstalling the chassis or working beside the
power.
4) Do not work alone if potential dangers exist.
5) Cut off the power before checkout.
6) If trouble happens, take the following measures:
A. Cut off the system’s power.
B. Alarm
C. Take proper measures to help persons who are hit by the
disaster. Artificial respiration is needed if necessary.
D. Seek for medical help, or judge the loss and seek for available
help.

2.2.4 Electrostatic Discharge Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may cause the switch to
malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge prevention, ensuring
the chassis connects the ground. Another measure is to wear the static-proof hand ring. If there is no
hand ring, use the metal clip with the metal cable to clip the unpainted metal part of the chassis. In
this case, the static is discharged to the ground through the metal cable of the clip. You can also
discharge the static to the ground through your body.
2.3 Requirements for Common Locations
This part describes the requirements for the installation locations.
2.3.1 Environment
The switch can be installed on the desk or the cabinet. The location of the chassis, cabinet planning
and indoor cabling are very important for normal system’s function. Short distance between devices,
bad ventilation and untouchable control plate will cause maintenance problems, systematic faulty and
breakdown.
For location planning and device locating, refer to section 2.3.2 “Location Configuration Prevention”.
2.3.2 Location Configuration Prevention
The following preventive measures assist you to design the proper environment for the switch.
Make sure that the workshop is well-ventilated, the heat of
electrical devices is well-discharged and sufficient air circulation is
provided for device cooling.
Avoid to damage devices by following the electrostatic discharge
prevention procedure.
Put the chassis at the place where cool air can blow off the heat
inside the chassis. Make sure the chassis is sealed because the
opened chassis will reverse the cool air flow.
2.3.3 Power Requirements
Make sure that the power supply has nice grounding and the power at the input side of the switch is
reliable. The voltage control can be installed if necessary. At least a 240 V, 10A fuse or a breaker is
provided in the phase line if you prepare the short-circuit prevention measures for a building.
Caution:

If the power supply system does not have good grounding, or the input power disturbs too
much and excessive pulses exist, the error code rate of communication devices increases and
even the hardware system will be damaged.
Chapter 3 Grounding
3.1 Connecting the Grounding Cable
Grounding is used to quickly release overvoltage and overcurrent induced by lightening for switch, and
to protect personal safety. Select the appropriate grounding method according to your needs.
3.1.1 With Grounding Bar
If a grounding bar is available at the installation site, follow the steps below.
Steps
1. Connect one end of the grounding cable to the binding post on the grounding bar.
2. Connect the other end of the grounding cable to the grounding terminal of the device and fix the
screw.
Figure 3-1 Grounding with Grounding Bar

3.1.2 Without Grounding Bar
If there is no grounding bar but the earth is nearby and the grounding body is allowed to be buried,
follow the steps below.
Steps
1. Bury an angle steel or steel pipe (≥ 0.5 m) into the mud land.
2. Weld one end of the grounding cable to the angle steel or steel pipe and embalm the welding point
via electroplating or coating.
3. Connect the other end of the grounding cable to the grounding terminal.
Figure 3-2 Grounding with Angle Steel

3.2 Connecting RJ45 Port
Use a network cable to connect the device to the RJ45 port of a peer device such as network camera,
NVR, switch, etc.
Figure 3-3 RJ45 Port Connection
3.3 Connecting SFP Optical Module
Connecting SFP optical module is supported when the device has a fiber optic port or a combo.
When connected to a network cable, the combo is a RJ45 port. When plugged into with an optical
module and connected to an optical fiber, the combo functions as a fiber optic port.
When connected to both the network cable and optical fiber at the same time, the port works as a
fiber optic port.
Steps
Caution
●Single-Mode optical module needs to be paired.
●Do not bend fiber optic (curvature radius ≥ 10 cm) overly.
●Do not look directly at fiber optic connector because the laser is harmful to eyes.
1. Connect the two paired SFP optical modules with an optical fiber.
2. Hold the SFP optical module from one side, and smoothly plug it into the device along with the SFP
port slot until the optical module and the device are closely attached.

3. After powering on the device, check the status of LINK/ACT indicator. If the indicator is lit, the link is
connected. If the indicator is unlit, the link is disconnected. Check the line, and make sure peer
devices have been started.
Chapter 4 Powering on the Device
Before powering your switch, make sure that:
●The operating power supply is compliant with rated input standard.
●Port cables and grounding cables are correctly connected.
●If there is outdoor cabling, connect a lightning rod and lightening arrester to the cable.
Caution
PoE power supply line and strong wire cannot be wired together, otherwise PD equipment or switch
ports will be burnt.
