CHAPTER 2 INSTALLATION
Before installing the switch, make sure that the following the "packing list" listed OK. If
any part is lost and damaged, please contact your local agent immediately. In addition,
make sure that you have the tools install switches and cables by your hands.
One Switch
One power cord
This User Guide
Mounting screws with two “L” planks
Note: This switch can be placed on a flat surface.
The site where you place the switch may greatly affects its performance. When
installing, take the following into your consideration.
2.1 Installation method
Follow the below guide to install the switch.
Please install the switch in a fairy cool and dry place. See the Technical
Specification for the acceptable temperature and humidity operation ranges.
Installing the switch on a sturdy, level surface that can support its weight
(at least 5KG).
Connect the power cord to the switch and the power outlet. The distance is less
than 150cm.
Leave at least 10cm (about 4 inches) of space at the front and rear of the switch
for ventilation.
2.2 Rack-mountable Installation
The switch is rack-mountable and can be installed on an EIA-11 inch equipment rack.
To do this, first, please install the mounting brackets on the switch’s side panels(one
on each side), secure them with the included screws, and then use the screws
provided with the equipment rack to mount the switch on the 11 inch rack.

Step 2
2.3 Turn on the switch
Please plug the power supply into the switch, the internal power system of the switch
can
auto-regulate the working power according to the actual input power. When the switch
is power on, the power indicator will be light on on the front panel of the switch shines.
Note:
Please confirm the voltage is correct before power on, otherwise the switch will be
damaged.
There is a power supply socket on the back panel of the 8 port PoE switch.
The power input is: 110V-240V.

2.5Network Connection
Connect your devices (computer, router, switch, etc.) to the ports with a
CAT-5/CAT-5e/CAT-6 network cable. Since the switch supports Auto MDI/MDI-X you
can use either a straight or crossed network cable.

2.6Switch connection to the PD
All ports of switch have POE power supply function, the maximum output power up to
30W each port, it can make PD devices, such as internet phone, network camera,
wireless access point work, provide five levels of 3.84 ~ 25.5W electric power request.
You only need to connect the switch POE port directly connected to the PD port by
network cable
CHAPTER 3 TROUBLE SHOOTING
The Switch can be easily monitored through panel indicators to assist you identify
some problems. This section describes common problems you may encounter and
where you can find possible solutions.
3.1Indicators
If Link indicator does not light up after making a connection, you may check whether
network interface (e.g., a network adapter card on the attached device), network cable,
or switch port is defective or not. Be sure the cable is plugged into both the Switch and
corresponding device. Verified the proper cable type is used and its length does not
exceed specified limits.
3.2Power
If the power indicator does not turn on when the power cord is plugged in, you may
have a problem with power outlet, or power cord. However, if the switch powers off
after running for a while, check for loose power connection, power loses or surges at
power outlet. If you still cannot resolve the problem, contact your local dealer for
assistance.
3.3Cable
RJ-45 Ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for
RJ-45 connections:
1. CAT-3/CAT-5/CAT-5e UTP cable when the switch connect with a 10-Base TX
device
2. CAT-5/CAT-5e/CAT-6 UTP cable when the switch connect with a 100-Base TX
device
3. Be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).

Appendix: The standard RJ-45 Introduction
Please note that cable-making methods, because cable which does not meet
the standards of the sequence data will make the data transmission speed
slow, unstable and even be blocked, the following chart represents that the
