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 work 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 lead 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

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:
Regular dust, keep the indoor air clean;
Make sure the equipment is well grounded to ensure smooth transfer of static electricity
Electromagnetic interference
Electromagnetic interference have an impact on the device capacitance, inductance and other
electronic components by capacitance, inductive coupling, impedance coupling and other
conductive, in order to reduce the adverse effects caused by electromagnetic interference,
please note the following：
Power supply system to take the necessary anti-grid interference measures;
Switches should be far away from high-frequency high-power, high-current devices, such as
wireless transmitters;
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：
Make sure the rack and the ground to maintain good contact;
Make sure the power outlet is in good contact with the earth;
Reasonable wiring, to avoid the internal sense ray;
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:
Make sure the rack or workbench is stable, strong, and can withstand at least 5.5Kg weight;
Make sure the rack has a good cooling system, or maintain good indoor ventilation;
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
Installation method
ELECTRA-T08 supports desktop mounting and rack mount.:
First, Check rack grounding and stability；
Second, Install the two L-brackets in the accessory on each side of the switch panel and
secure with the screws provided in the accessory
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.

Chapter3 Hardware connection
3.1RJ45 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
ELECTRA-T08 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;
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
Check whether the outlet power supply meets the switch specifications;
Check the power, switches, racks and other equipment have been properly grounded;
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
3.5 Web Login
Step1、In the normal operation of the device, connect the computer to the switch's RJ45 port by
network cables
Step 2、Manually changed the computer IP address to 192.168.254.X (X is 2 ~ 254), subnet mask is
255.255.255.0
Step3、Open computer's browser, type 192.168.254.1 in the address box, hit the Enter key

Step4、Enter the default username and password “admin” and then click Login
Step5、Entered the switch web management interface successfully when you see picture as below,
you can begin to configure the switch
