Introduction
Chapter 1 Introduction
1.1 Product Overview
TL-R480T+ is a product designed for small business. It features three free changeable
ports that can be set to either LAN or WAN, allowing the router to support up to four
WAN ports to satisfy various Internet access requirements through one device. At the
same time, network traffic is managed to ensure that data is properly distributed to
each port. TP-Link TL-R480T+ will provide you consistent network uptime and reliable
Ethernet connectivity.

2.2 Safety Precautions
To avoid any device damage and bodily injury caused by improper use, please observe
the following rules.
■Safety Precautions
■Keep the power off during the installation.
■Wear an ESD-preventive wrist strap, and make sure that the wrist strap has a good skin
contact and is well grounded.
■Use only the power cord provided with the router.
■Make sure that the supply voltage matches the specifications indicated on the rear
panel of the router.
■Ensure the vent hole is well ventilated and unblocked.
■Do not open or remove the cover of the router.
■Before cleaning the device, cut off the power supply. Do not clean it by the waterish
cloth, and never use any other liquid cleaning method.
■Site Requirements
To ensure normal operation and long service life of the device, please install it in an
environment that meets the requirements described in the following subsection.

Temperature/Humidity
ȭ
ȭ
Please keep a proper temperature and humidity in the equipment room. Too high/low
humidity may lead to bad insulation, electricity leakage, mechanical property changes
and corrosions. Too high temperature may accelerate aging of the insulation materials
and can thus significantly shorten the service life of the device. For normal temperature
and humidity of the device, please check the following table.
Environment Temperature Humidity
Operating 0℃to 40℃10% to 90%RH Non-condensing
Storage -40℃to 70℃5% to 90%RH Non-condensing
Clearness
The dust accumulated on the router can be absorbed by static electricity and result
in poor contact of metal contact points. Some measures have been taken for the
device to prevent static electricity, but too strong static electricity can cause deadly
damage to the electronic elements on the internal circuit board. To avoid the effect of
static electricity on the operation of the router, please attach much importance to the
following items:
■Dust the device regularly, and keep the indoor air clean.
■Keep the device well grounded and ensure static electricity has been transferred.
Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be
affected by external interferences, such as conducted emission by capacitance
coupling, inductance coupling, and impedance coupling. To decrease the interferences,
please make sure to take the following measures:
■Use the power supply that can effectively filter interference from the power grid.
■Keep the device far from high-frequency, strong-current devices, such as radio
transmitting station.
■Use electromagnetic shielding when necessary.

05

Lightening Protection
Extremely high voltage currents can be produced instantly when lightning occurs and
the air in the electric discharge path can be instantly heated up to 20,000℃.As this
instant current is strong enough to damage electronic devices, more effective lightning
protection measures should be taken.
■Ensure the rack and device are well earthed.
■Make sure the power socket has a good contact with the ground.
■Keep a reasonable cabling system and avoid induced lightning.
■Use the signal SPD (Surge Protective Device) when wiring outdoor.
Note:
For detailed lightning protection measures, please refer to Chapter 3 Lightning
Protection.
Installation Site
When installing the device on a rack or a flat workbench, please note the following
items:
■The rack or workbench is flat and stable, and sturdy enough to support the weight of
5.5kg at least.
■The rack or workbench has a good ventilation system. The equipment room is well
ventilated.
■The rack is well grounded. Keep the power socket less than 1.5 meters away from the
device.
2.3 Installation Tools
■Phillips screwdriver
■ESD-preventive wrist wrap
■Cables
