Introduction
Chapter 1 Introduction
1.1 Product Overview
TP-Link JetStream L2 Managed Switch, designed for workgroups and departments,
provides wire-speed performance and abundant layer 2 management features.
It provides a variety of service features and multiple powerful functions with high
security.
The EIA-standardized framework and smart configuration capacity can provide
flexible solutions for a variable scale of networks. ACL, 802.1x and Dynamic ARP
Inspection provide robust security strategies. QoS and IGMP snooping/filtering
optimize voice and video application. Link aggregation (LACP) increases aggregated
bandwidth, optimizing the transport of business critical data. SNMP, RMON, WEB/
CLI/Telnet Log-in bring abundant management policies. TP-Link JetStream L2
Managed Switch integrates multiple functions with excellent performance, and is
friendly to manage, which can fully meet the need of the users demanding higher
networking performance.

Introduction
Note: The port 25–28 of the switch are “Combo” ports. A “Combo” port consists of a
RJ45 port and an SFP port, and the two ports share the same LED.

Designed to connect with the serial port of a computer or terminal for monitoring
and configuring the switch.
10/100Mbps Port
Designed to connect to the device with a bandwidth of 10Mbps or 100Mbps.
Each has a corresponding 10/100M LED.
10/100/1000Mbps Port
Designed to connect to the device with a bandwidth of 10Mbps, 100Mbps or
1000Mbps. Each has a corresponding 1000M LED.
SFP Port
Designed to install the SFP module. The switch features some SFP transceiver
slots that are shared with the associated RJ45 ports. The associated two ports
are referred as a “Combo” port, which means they cannot be used simultaneously,
otherwise only SFP port works.

Grounding Terminal
The switch already comes with lightning protection mechanism. You can also
ground the switch through the PE (Protecting Earth) cable of AC cord or with
Ground Cable. For detailed information, please refer to Chapter 3 Lightning
Protection.
Power Socket
Connect the female connector of the power cord here, and the male connector to
the AC power outlet. Please make sure the voltage of the power supply meets the
requirement of the input voltage (100-240V~ 50/60Hz).
Caution: Please use the provided power cord.

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 switch.
■Make sure that the supply voltage matches the specifications indicated on the
rear panel of the switch.
■Ensure the vent hole is well ventilated and unblocked.
■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.
■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
40℃
0℃

04
L2 Managed Switch
Installation
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 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, strong-current devices, such as radio
transmitting station.
■Use electromagnetic shielding when necessary.
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

05
L2 Managed Switch
Installation
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
Note: These tools are not provided with our product. If needed, please purchase
them.
