Chapter 2 Hardware Connection
2.1 Connecting RJ45 port
Connect the switch and the RJ45 port of the peer network device with a network
cable.
2.2 Connecting SFP Ports
The SFP port of the SE-4048-PoE supports only 10 Gigabit fiber modules. It is
recommended to use standard SFP module products.
The process of installing a fiber module on a switch is as follows:
1. Grasp the fiber module from the side and insert it smoothly along the SFP port
slot of the switch until the fiber module is in close contact with the switch;
2. Confirm the Rx and Tx ports of the fiber module when connecting. Insert one
end of the fiber into the Rx and Tx ports to ensure that the Tx and Rx ends of the
interface are correctly connected, and the other end of the fiber is connected to
another device.
3. After power-on, check the status of the corresponding indicator. If the indicator
is on, the link is up. If the indicator is off, the link is down. Check the line and
confirm that the peer device is enabled.

Note:
It is not allowed to excessively bend the fiber, and its radius of curvature should be no less than 10
cm;
Ensure the cleanliness of the fiber end face;
Please do not look directly into the fiber optic connector with your eyes, as this may cause eye
damage.
2.3 Check before power-on
Check that the power supply of the power outlet meets the switch specifications.
Check that the power supply, switch, and rack are properly grounded.
Check whether the switch is connected to other network devices.
2.4 device initialization
The switch will automatically initialize after the power is turned on and the power switch is turned
on.
The indicator light will appear as follows:
1. After the power is turned on, the power indicator remains steady. When SYS enters the
flashing state, the system runs normally.
2. The indicator of each port indicates the connection status of each port, indicating that the
switch has started to work normally.

Chapter 3: Product Installation
3.1Installation Precautions
Note: To avoid damage to the equipment and personal injury caused by improper use,
please observe the following precautions.
safety precautions
❖power supply remains off during the installation process. Wear an ESD-preventive wrist
strap and ensure that the ESD-preventive wrist strap is in good contact with the skin to
avoid potential safety hazards.
❖Switch only can work normally under the correct power supply. Please confirm that the
power supply voltage matches the voltage indicated by the switch.
❖Before powering on the switch, please make sure that the power circuit is not overloaded,
so as not to affect the normal operation of the switch and cause unnecessary damage.
❖To avoid the risk of electric shock, do not open the case while the switch is working, even
if it is not charged, do not open it yourself;
❖Before cleaning the switch, first pull out the power plug of the switch. Do not wipe with a
moist fabric. Do not use liquid to clean.
humidity
In order to ensure long-term stable operation of the switch and prolong its service life, please
maintain a certain temperature and humidity in the environment. Too high or too low ambient
humidity is likely to cause leakage, deformation and even corrosion of metal parts. If the
temperature is too high, the aging process of the insulation material will be accelerated, which will
seriously affect the service life of the equipment. The normal operation and storage
temperature / humidity of this series of switches are as follows:
Environmental description

0℃~40℃
10%～90% RHNon-condensing

elevation
Products with this mark are only suitable for safe use in areas below 2000m above sea level.
dustproof
Dust falling on the surface of the switch can cause electrostatic adsorption and poor contact of the
metal contacts. Although the device itself has made certain measures in anti-static, when the static
electricity exceeds a certain intensity, it will still cause fatal damage to the electronic components
on the internal circuit board. To avoid the static electricity affecting the normal operation of the
device, please pay attention to the following:
1. Regular dust removal to keep indoor air clean;
2. Make sure that the equipment is well grounded to ensure the smooth transfer of static
electricity.
interference
Electromagnetic interference will affect the electronic components such as capacitors and
inductors inside the device by means of capacitive coupling, inductive coupling, impedance
coupling, etc. To reduce the adverse effects caused by electromagnetic interference, please pay
attention to the following:
1. The power supply system takes necessary measures against grid interference;
2. The switch should be away from high-frequency, high-power, high-current equipment,
such as wireless transmitters;
3. Take electromagnetic shielding measures when necessary.
lightning protection needs
When a lightning strike occurs, a strong cur rent is generated in an instant, and the air in the
discharge path is instantaneously heated to 20,000 degrees Celsius, and an instantaneous large
current is enough to cause fatal damage to the electronic device. For better lightning protection,
please note the following:
1. Confirm that the rack is in good contact with the ground;
2. Make sure the power outlet is in good contact with the ground;
3. Reasonable wiring to avoid internal induction lightning;
4. When using outdoor wiring, it is recommended to use a signal lightning arrester.

Installation rack requirements
Regardless of whether the switch is installed in a rack or other horizontal workbench, please note
the following:
1. Verify that the rack or table is stable, strong, and capable of withstanding a weight of at
least 5.5 kg;
2. Confirm that the rack itself has a good cooling system, or keep the room well ventilated;
3. Make sure the rack is well grounded, and the distance between the power socket and the
switch is less than 1.5 meters.
tool preparation
The Phillips screwdriver, electrostatic wrist strap, and cable fiber may be used during installation.
3.2 Product Installation
19inch standard rack mount
The SE-4048-PoE is designed to fit the standard 19-inch rack and can be easily mounted to the
rack. The specific installation steps are as follows:
1. Check the grounding and stability of the rack;
2. Install the two L-shaped brackets in the accessories on both sides of the switch panel and
fix them with the screws provided in the accessories.
3. Place the switch in the proper position in the rack and support it by the bracket. Fix the L-

bracket to the guide groove fixed at both ends of the rack with screws to ensure that the
switch is installed on the rack stably and horizontal.
Note:
Good grounding of the rack is an important guarantee for anti-static, anti-leakage, lightning
protection and anti-interference of the equipment. Therefore, ensure that the grounding wire of
the rack is properly installed.
The equipment installed in the rack is generally from bottom to top to avoid overload
installation;
Avoid placing other heavy objects on the surface of the switch to avoid accidents;
Ensure heat dissipation and air circulation.
