Unmanaged PoE+ Switch
Introduction
Chapter 1 Introduction
1.1 Product Overview
TL-SL1218P, TL-SL1218MP, and TL-SL1226P are Power Sourcing Equipment (PSE*) which require
no configurations. The 10/100 Mbps RJ45 ports on the switch support the Power over Ethernet
(PoE*) function, which can automatically detect and supply power to those powered devices (PDs*)
complying with IEEE 802.3af and IEEE 802.3at.
Note:
■*PSE is a device (switch or hub for instance) that will provide power in a PoE setup.
■*PoE is a technology that describes a system to transmit electrical power, along with data, to
remote devices over standard twisted-pair cable in an Ethernet network.
■*PD is a device powered by a PSE and thus consumes energy. Examples include powering
IP telephones, wireless LAN access points, network cameras, network hubs, embedded
computers and so on.

Unmanaged PoE+ Switch
Introduction
10/100 Mbps RJ45 Port (Port 1–16)
The ports are designed to connect to devices with a bandwidth of 10 Mbps or 100 Mbps. The ports
can provide power and transmit data for PDs. The maximum PoE power for each PoE port is 30 W. The
maximum PoE power for all PoE ports is 150 W (for TL-SL1218P)/250 W (for TL-SL1218MP). The ports
can also connect to non-PoE devices, but only transmit data.
10/100/1000 Mbps RJ45 Port (Port 17–18)
The ports are designed to connect to devices with a bandwidth of 10 Mbps, 100 Mbps or 1000 Mbps.
SFP Port (Port 18F for TL-SL1218P/Port 17F–18F for TL-SL1218MP)
The ports are designed to install the SFP module. An SFP Port (port 17F/port 18F) and the associated
10/100/1000 Mbps RJ45 Port (port 17/port 18) are called a “Combo” port, which means they cannot be
used simultaneously; otherwise, only the SFP port works.

2.2 Safety Precautions
To avoid any device damage and bodily injury caused by improper use, you should 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 switch.
■Make sure that the supply voltage matches the specifications indicated on the rear panel of the
switch.
■Ensure that the switch is installed in a well-ventilated environment and its ventilation hole is not
blocked.
■Do not open or remove the cover of the switch.
■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.
■Place the device with its bottom surface downward.

Unmanaged PoE+ Switch
Installation
Keep the equipment room at an appropriate level of temperature and humidity. Too much or too
little humidity may lead to bad insulation, leakage of electricity, mechanical property changes,
and corrosion. High temperatures may accelerate aging of the insulation materials, significantly
shortening the service life of the device. To find out the best temperature and humidity conditions
for the device, check the following table.
Environment Temperature Humidity
Operating 0 ℃to 50 ℃10% to 90%RH Non-condensing
Storage -40 ℃to 70 ℃5% to 90%RH Non-condensing
Clearness
The dust accumulated on the switch 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 switch, 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 and strong-current devices such as radio transmitting
station.
■Use electromagnetic shielding when necessary.
Lightning 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 that the rack and device are well earthed.

Unmanaged PoE+ Switch
Installation
■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, go to https://www.tp-link.com/support, search
the model number of your switch and go to the product Support web page, refer to the
Lightning Protection Guide from the Related Documents:
https://www.tp-link.com/us/conguration-guides/lightning_protection_guide/.
Installation Site
When installing the device on a rack or a flat workbench, attach much importance to the following
items:
■The rack or workbench is flat, stable, and sturdy enough to support the weight of 5.5 kg at least.
■The rack or workbench has a good ventilation system. The equipment room is well ventilated.
■The rack is well grounded. Keep the device less than 1.5 meters away from the power socket.

3.4 Power On
Plug the negative connector of the provided power cord into the power socket of the device and plug
the positive connector into a power outlet as the following figure shows.
Figure 3-3 Connecting to Power Supply
Note:
The gure is to illustrate the application and principle. The provided plug and the socket in
your region may dier from the gures above.
3.5 Initialization
After the device is powered on, it begins the Power-On Self-Test. A series of tests run automatically
to ensure the device functions properly. During this time, its LED indicators will respond as follows:
1. The PWR LED indicator will light up and keep on.
2. After the initialization, the Link/Act LED indicator for 10/100/1000 Mbps ports and SFP ports will
first turn green and then yellow momentarily, and finally turn off again.
3. After the initialization, the LED indicators for PoE status and PoE max will flash momentarily and
then turn off again.
Finally, all LED indicators will work normally.

12 Appendix A Troubleshooting
Unmanaged PoE/PoE+ Switch
Appendix A Troubleshooting
Q1. Why is the PWR LED not lit?
The PWR LED should be lit when the power system is working normally. If the PWR LED is not lit,
check as follows:
A1: Make sure the switch is connected to the power source with the AC power cord properly.
A2: Make sure the voltage of the power supply meets the requirements of the input voltage of the
switch.
A3: Make sure the power source is on.
Q2. Why is the Link/Act LED not lit when a device is connected to the corresponding
port?
It is recommended that you check the following items:
A1: Make sure that the cable connectors are firmly plugged into the switch and the device.
A2: Make sure the connected device is turned on and working well.
A3: The cable length should be less than 100 meters (328 feet). If Extend Mode is enabled, it
should be less than 250 meters (820 feet).
Q3. Why are some ports not supplying power for PoE devices?
If total power consumption of connected PoE devices exceeds the maximum PoE power,
the system will cut off the power to ports with larger serial numbers to compensate for the
overload. Therefore, port 5–16 (for TL-SL1218P), port 9–16 (for TL-SL1218MP) and port 9–24 (for
TL-SL1226P) may not supply power for connected PoE devices.
For example, on TL-SL1218MP, port 1–7 and port 9 are consuming 30 W respectively. If an
additional PoE device with 11 W is inserted to port 8, the system will cut off the power to port 9.
