10/100/1000Mbps Port
Designed to connect to the device with a bandwidth of 10Mbps, 100Mbps or 1000Mbps. Each has a
corresponding Link/Act LED.
SFP Port
Designed to install the SFP transceiver. These four SFP transceiver slots 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 RJ45 port works. The SFP ports support 1000M SFP module connection
only.
SFP+ Port
Designed to install the 10Gbps SFP+ transceiver or SFP+ cables. T3700G-28TQ/T3700G-52TQ also
provides an interface card slot on the rear panel to install the expansion card (TX432 of TP-Link for
example). If TX432 is installed, you get another two 10Gbps SFP+ ports.
Console Port (USB/RJ45)
Designed to connect with the USB port of a computer for monitoring and conguring the switch. The
switch has an RJ45 console port and a micro-USB console port available. Console input is active on
only one console port at a time. By default, the micro-USB connector takes precedence over the RJ45
connector.
USB 2.0 Interface
USB 2.0 interface is used to connect peripheral equipment.
Management Port
Designed to connect the device with a bandwidth of 10Mbps, 100Mbps or 1000Mbps. It has a
corresponding MGMT LED on the front panel. You need assign an IP address for the port to manage the
switch.
Unit ID LED
Designed to display the stack Unit ID of the switch. For the switch that does not join any stack system, it
displays its default Unit ID. To modify the default unit number, please logon to the GUI of the switch and
go to Stack→Stack Management→Switch Renumber page.

JetStream L3 Stackable Managed Switch
04 Introduction
Interface Card Slot
Designed to extend the interfaces. You can select a TP-Link Interface Card (TX432 for example) for your
switch if needed. For how to install an Interface Card, please refer to 3.4 Installing and Removing the
Interface Card.
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 the Lightning Protection Guide from the training center of our website
http://www.tp-link.com/en/conguration-guides.html.
Power Supply Module
The AC Power Supply Module PSM150-AC is installled in the switch. The malfunctioned PSM150-AC
can be replaced with a TP-Link power supply module of the same model. Its input voltage is 100-240V~
50/60Hz.
The AC Power Supply Module is fully hot swappable, helping to ensure no system interruption during
installation or replacement. For how to install or remove the Power Supply Module, please refer to 3.3
Installing and Removing the Power Supply Module.
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.
■Place the device with its bottom surface downward.

06 Preparing for 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 this instant current is strong
