Chapter 2 Installation
2.1 Installation Precautions
Note: To avoid improper use of equipment damage and personal injury, please observe the
following precautions
◼Installation safety precautions
•The power should be kept off during the installation, while wearing anti-static wrist,
and to ensure well touch between anti-static wrist and skin to avoid potential safety
hazard;
•The switch just works normally when it is powered by the correct power supply.
Make sure that the power supply voltage matches the voltage indicated by the switch
•Before powering on the switch, make sure that the power circuit is not overloaded,
which may affect the normal operation of the switch and even cause unnecessary
damage
•To avoid the risk of electric shock, do not open the case while the switch is working.
Do not open the case even when it is not powered
•Before cleaning the switch, unplug the switch from the power cord and do not wipe it
with wet cloth. Do not wash it with liquid
◼Temperature and humidity
To ensure the long-term stability working of the switch, please maintain a certain temperature
and humidity environment. High or low humidity easily led to leakage of insulation materials,
deformation and even the corrosion of metal parts, the temperature is too high will accelerate
the aging process of insulating materials, seriously affecting the service life of equipment. The
normal operation of this series of switches and storage temperature / humidity are as follows
Environmental description

◼Altitude
Products with this logo are only for safe use in areas below 2000m altitude
◼Dust-proof
Dust on the switch surface will cause electrostatic adsorption, poor contact of the metal
contacts. Although the device itself has done some measures in anti-static, but when the static
electricity exceeds a certain intensity, it will still cause fatal damage to the electronic
components on the internal circuit board. In order to prevent static electricity from affecting
the normal operation of the equipment, please note the following:
1. Regular dust, keep the indoor air clean;
2. Make sure the equipment is well grounded to ensure smooth transfer of static electricity
◼Electromagnetic interference
Electromagnetic interference has an impact on the device capacitance, inductance and other
electronic components by capacitive, inductive coupling, impedance coupling and other
conductive, in order to reduce the adverse effects caused by electromagnetic interference,
please note the following：
1. Power supply system to take the necessary anti-grid interference measures;
2. Switches should be far away from high-frequency high-power, high-current devices, such
as wireless transmitters;
3. If necessary, take electromagnetic shielding measures
◼Lightning protection
When a lightning strike occurs, a strong current will be generated in an instant cause fatal
damage to electronic equipment. To achieve better lightning protection, please note the
following：
1. Make sure the rack and the ground to maintain good contact;
2. Make sure the power outlet is in good contact with the earth;
3. Reasonable wiring, to avoid the internal sense ray;
4. Outdoor wiring, it is recommended to use the signal lightning protection device

◼Installation desk requirement
Regardless of whether the switch is installed in a rack or on another horizontal workbench,
be aware of the following:
1. Make sure the rack or workbench is stable, strong, and can withstand at least 5.5Kg
weight;
2. Make sure the rack has a good cooling system, or maintain good indoor ventilation;
3. Make sure the rack is well grounded, the power outlet and switch are within 1.5 meters
◼Prepare tools for installation
You may need to use a screwdriver during installation, electrostatic wrist strap, fiber optic
cable and other tools to prepare your own
2.2 Product installation
19-inch standard rack installation
SL-224-H-P300 is designed according to the standard 19-inch rack size, you can easily install
to the rack, the specific installation steps are as follows:

Page13
Third, place the switch in an appropriate place in the rack and be supported by the bracket.
Screw the L-shaped bracket to the guide groove fixed on both ends of the rack to ensure that
the switch is stable and horizontally installed on the rack
Note：
Good grounding rack is anti-static equipment, anti-leakage, lightning protection, anti-
jamming important guarantee, so to ensure that the rack ground wire properly installed;
Installation equipment within the rack from the bottom up, to avoid overload installation;
Avoid placing other heavy objects on switch to avoid accidents;
Ensure heat dissipation and air circulation.

Chapter 3: Hardware connection
3.1 RJ45 port connection
Connect the RJ45 port of the switch and the corresponding network device via cables, the PoE
power supply function of the switch is default enabled on the downlink port of the switch,
which can be used for IEEE802.3af or IEEE802.3at standards powered devices such as APs,
bridges, and network cameras
Note：When the switch connected workstations, servers, routers or other ethernet devices the
cable length should be within 100 meters;
The Auto-MDI / MDIX ethernet interface is enabled by default. Category 5, the standard
network cable or crossover cable can be used for Ethernet connection.
Do not connect the RJ45 port to the phone line
3.2 SFP Port connection
SL-224-H-P300 SFP port only support Gigabit fiber module. Recommended use of standard
SFP module products
The process of installing a fiber module on a switch is as follows:
First, grasp the optic fiber module from the side, insert it smoothly along the SFP port slot until
the optic fiber module and switch are in close contact;

SL-224-H-P300
Tel:[phone] , Fax:[phone]
Www.techs.is , [e-mail]
Page15
Second, confirm the Rx and Tx ports of the fiber module when connecting, insert one end of
the fiber into the Rx and Tx ports correspondingly, ensure that the Tx and Rx ends of the
interface are connected correctly and the other end of the fiber is connected to another device;
Third, please check the corresponding indicator light status after power on. If the light blinking
that the link is properly connected, if the light is off, the link is failure, please check the line to
confirm that the corresponding equipment is enabled.
Note：Does not allow excessive bending fiber, the radius of curvature should not be
less than 10cm;
Ensure the cleanliness of the fiber surface;
Please do not look directly into the optical fiber connector with your eyes as this may cause
eye injury
3.3 Check before power on
1. Check whether the outlet power supply meets the switch specifications;
2. Check the power, switches, racks and other equipment have been properly grounded;
3. Check whether the switch and other network devices are connected properly .
3.4 Device initialization
The switch automatically initializes when the power switch is turned on.
Indicator will appear the following situation:
After the power is turned on, the power indicator remains on, the other indicator is off at this
time;
After about 1 second, all lights except for the power light turn on for about 35 seconds and
then turn off; when the SYS light goes flashing, the system runs normally
Port LEDs indicates the connection status of each port, indicating that the switch has started
to work normally
