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.

Interface Description
Interface Description
WAN The WAN port is designed to connect the Router to the interface provided
by ISP via the RJ45 cable
LAN The LAN port is designed to connect the Router to the local PCs or
switches by the RJ45 cable
Console
The Console port is designed to connect with the serial port of a computer
or terminal to check and monitor some simple system information of the
Router
Reset
With the Router powered on, use a pin to press and hold the Reset button (about 5
seconds) until the SYS LED ashes quickly. Then release the button and wait for the
Router rebooting to its factory default settings.

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

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℃~ 40℃10% ~ 90%RH Non-condensing
Storage -40℃~ 70℃5% ~ 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.

Installation

05
Load Balance Broadband Router
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
S
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.
